Clarinet Extended Techniques: Multiphonics, Circular Breathing, Tonguing & More

Clarinet extended techniques are unconventional sound-production methods used to create colors beyond standard tone and articulation. Common examples include multiphonics, circular breathing, flutter-tonguing, slap-tonguing, key clicks, growling, microtones and altissimo harmonics. Each technique relies on specific embouchure, fingering, airflow and tongue adjustments that can be learned through slow, structured drills and careful equipment setup.

What are clarinet extended techniques?

Clarinet extended techniques are nontraditional ways of producing sound that go beyond standard tone, articulation and range. They include multiphonics, circular breathing, slap- and flutter-tonguing, extreme altissimo, microtones, key clicks and vocal effects. Composers and improvisers use these sounds to create new textures, rhythmic layers and expressive colors that traditional technique cannot supply.

For an intermediate or advanced player, extended techniques are not gimmicks. They are specific, repeatable skills that rely on clarinet acoustics, embouchure flexibility and detailed control of air and tongue. When practiced methodically, they become as reliable as normal articulation or register changes, and they significantly expand your repertoire options in contemporary, jazz and experimental music.

Multiphonics: fingerings, singing-while-playing, and practice progressions

Multiphonics are sounds where the clarinet produces more than one pitch at the same time. They arise from carefully chosen fingerings, subtle embouchure adjustments and very steady air. The clarinet's cylindrical bore and register vent normally favor a single harmonic, so multiphonics work by destabilizing that preference and allowing two or more partials to speak together.

There are two main multiphonic approaches for clarinetists: special fingerings that split the air column into multiple partials, and singing-while-playing, where the vocal folds add a second pitch. Both methods demand relaxed but stable embouchure and airstream. Excess tension or unsteady air usually collapses the sound back to a single pitch or produces squeaks.

Core multiphonic fingerings to start with

Many published fingering charts exist, but a few stable combinations work well for most B-flat clarinets. Always test on your own setup, since mouthpiece, reed and bore affect results. Start in the chalumeau and throat tones, where air demands are lower and pitch control is easier.

Try these commonly reliable multiphonic starting points (written pitches for B-flat clarinet):

• Low F multiphonic: Finger low F as usual, then add right-hand E/B key and half-hole the left index finger. Use mezzo-forte air and slightly looser embouchure.
• Low G multiphonic: Finger low G, add side F-sharp key and slightly vent the register key. Aim for a soft dynamic and very steady air.
• Throat A multiphonic: Finger A, add side keys 1 and 2, and half-hole the left index finger. Think warm, covered tone with minimal jaw pressure.

Each fingering typically produces a characteristic dyad or cluster. Use a tuner or piano to identify the pitches. Some players mark successful fingerings in their parts with small dyad labels (e.g., G/E) to remember target sounds.

Singing-while-playing multiphonics

Singing-while-playing creates multiphonics by combining the clarinet pitch with a sung pitch. This method is more flexible than special fingerings and works on almost any written note. The key is to separate throat and tongue tension from the vocal folds so both the sung pitch and clarinet tone remain clear.

Begin with a comfortable mid-register note, such as written G in the staff. Play the note softly, then hum the same pitch without stopping the air. Once that feels stable, gradually slide your sung pitch up or down a third or fifth while keeping the clarinet pitch steady. The interference between the two pitches creates beating and multiphonic textures.

Step-by-step multiphonic practice progression

A clear progression helps avoid frustration and random squeaks. Use a metronome and tuner when possible, and record short clips to track consistency. Aim for repeatable results on each fingering before moving on.

1. Long-tone foundation: Spend 3-5 minutes on soft, stable long tones in chalumeau and throat tones. Focus on relaxed embouchure and steady air.
2. Single fingering focus: Choose one multiphonic fingering. Start at piano, crescendo to mezzo-forte, then decrescendo, all in one breath.
3. Pitch identification: Use a tuner or piano to identify both pitches. Sing them separately, then imagine them while playing the multiphonic.
4. Dynamic control: Practice short swells (2 beats crescendo, 2 beats decrescendo) without losing both pitches.
5. Articulation tests: Add very light tonguing at the start of the sound. Avoid heavy attacks that collapse the multiphonic.

Repeat this process with each new fingering. For singing-while-playing, follow the same progression but vary the sung pitch while keeping the clarinet pitch stable. Over time, you will build a small, reliable vocabulary of multiphonic sounds.

Troubleshooting unstable multiphonics

Unstable multiphonics usually come from three sources: fingerings that do not suit your instrument, inconsistent air or embouchure that is too tight or too loose. Address each systematically rather than guessing. Small adjustments often make the difference between chaos and a controlled dyad.

• Symptom: Only one pitch sounds. Probable cause: Embouchure too tight or air too weak. Fix: Loosen jaw slightly, increase air speed, and try softer dynamic.
• Symptom: Random squeaks or jumps. Probable cause: Overblowing into higher partials. Fix: Reduce air pressure slightly and stabilize tongue position.
• Symptom: Sound collapses when adding articulation. Probable cause: Tongue attack too strong. Fix: Use breath attacks or very light tonguing at the reed tip.

Circular breathing: step-by-step method and drills

Circular breathing lets you maintain a continuous tone by using air stored in your cheeks while you inhale quickly through your nose. On clarinet, it is especially useful for long multiphonics, drones, minimalist passages and contemporary repertoire where breaks are not possible. The skill is mechanical and learnable with short, consistent drills.

The process has four phases: fill the cheeks, squeeze air out with cheek muscles while inhaling through the nose, reconnect lung air, and return to normal blowing. At first, the tone will wobble or thin out during the switch. Over time, you can make the transition almost inaudible, even in exposed solo passages.

Dry-land circular breathing drills (no clarinet)

Start without the instrument to isolate the cheek and nose coordination. Use water-straw drills and air-only exercises to build the basic motion. Aim for short, repeatable cycles before trying to sustain long phrases.

1. Cheek storage: Fill your cheeks with air, then close the back of your throat as if saying “ng.” Practice gently squeezing air out through pursed lips using only cheek muscles.
2. Nose inhale coordination: While squeezing air from your cheeks, inhale quickly through your nose for 1 second, then stop. Repeat 10 times.
3. Straw-in-water drill: Place a straw in a glass of water and blow bubbles. When cheeks are full, maintain bubbles by squeezing cheeks while inhaling through your nose.

Applying circular breathing to the clarinet

Once the basic motion is comfortable, transfer it to the clarinet on an easy mid-register note, such as written G or A in the staff. Use a comfortable dynamic (mezzo-piano) and a reed that responds easily. The goal is not volume but continuity of sound during the switch.

1. Cheek-fill on clarinet: Play a soft long tone, then briefly puff the cheeks while still blowing from the lungs. This stores a small air reserve.
2. Cheek-squeeze phase: Close the back of the throat, squeeze air from the cheeks to keep the tone going, and relax abdominal support briefly.
3. Nose inhale: While cheeks are squeezing, inhale through the nose for 1 second. Then reopen the throat and reconnect lung air smoothly.
4. Short cycles: Aim for 2-3 second cycles where the switch is audible but the tone does not stop. Gradually lengthen the overall note.

Step-by-step circular breathing practice plan

A structured plan helps you measure progress and avoid strain. Keep sessions short but frequent. Fatigue in the cheeks or throat is a sign to rest and reset your coordination rather than push harder.

• Week 1: 5 minutes per day on straw bubbles, 1-second nose inhales, 10-15 repetitions.
• Week 2: 5 minutes per day on clarinet long tones with 1-second cheek-squeeze cycles, aiming for 5-10 seconds of continuous sound.
• Week 3-4: Increase continuous tone to 20-30 seconds, add simple scale fragments while circular breathing.
• After 1 month: Integrate circular breathing into slow excerpts or drones in contemporary pieces.

Troubleshooting circular breathing problems

Circular breathing failures usually show up as sudden tone drops, nasal noise or dizziness. Each symptom points to a specific mechanical issue. Address the cause, then return to shorter cycles before attempting long phrases again.

• Symptom: Tone stops briefly during inhale. Probable cause: Gap between cheek air and lung air. Fix: Overlap cheek squeeze slightly longer before reopening the throat.
• Symptom: Audible “bump” or pitch change. Probable cause: Cheek pressure too weak or too strong. Fix: Practice 1-2 second cheek-only tones to find a stable pressure.
• Symptom: Dizziness or tension. Probable cause: Over-breathing or neck tension. Fix: Take smaller nose inhales and relax shoulders and jaw.

Tonguing techniques: flutter-tonguing, slap-tonguing, double & triple tonguing

Extended tonguing techniques add new textures, from buzzing rolls to percussive pops and rapid articulations. Clarinetists use flutter-tonguing for tremolo-like effects, slap-tonguing for sharp attacks, and double or triple tonguing for fast repeated notes. Each technique builds on basic articulation but changes tongue placement and air use.

Because the reed is sensitive, clarity depends on precise tongue contact and consistent air. Heavy pressure or uncontrolled motion can damage reeds or produce unwanted squeaks. Start softly, with short practice bursts, and use reeds that respond easily without excessive resistance.

Flutter-tonguing on clarinet

Flutter-tonguing creates a rapid rolling or growling effect by vibrating the tongue while blowing. There are two main methods: front-of-tongue roll (trill “r” like in Spanish) and uvular flutter (back-of-throat gargle). Many clarinetists find the uvular method more reliable, especially if they cannot roll an “r” naturally.

To practice uvular flutter, produce a soft gargling sound in the throat while blowing air without the clarinet. Then add the mouthpiece and barrel only, maintaining the flutter. Once that feels stable, assemble the clarinet and try flutter-tongue on long tones in the middle register, starting at piano and gradually increasing dynamic.

Slap-tonguing: percussive attacks

Slap-tonguing produces a sharp, popping attack as the tongue releases from the reed. On clarinet, it can be pitched (with clear note center) or unpitched (more like a click). The basic motion is similar to creating suction with the tongue on the reed, then releasing it quickly to let the reed snap back.

Begin by placing the tongue flat against the reed, creating a seal. Gently suck the reed onto the tongue, then pull the tongue away quickly to make a pop without blowing. Once you can create a consistent pop, add a small burst of air at the release to produce a pitched slap. Use soft reeds at first to reduce risk of chipping.

Double and triple tonguing for fast passages

Double and triple tonguing help with very fast repeated notes or articulation patterns that exceed your single-tongue speed. Clarinetists often use syllables like “ta-ka” or “da-ga” for double tonguing, and “ta-ka-ta” or “da-ga-da” for triple tonguing. The back syllable uses a slightly more rear tongue position but must still contact near the reed tip.

Practice away from the clarinet first, speaking the syllables in rhythm. Then tongue on the mouthpiece alone, aiming for even volume and tone between front and back syllables. Finally, apply to simple scale fragments in the middle register, starting slowly and increasing tempo only when clarity is consistent.

Step-by-step slap-tonguing drill sequence

Slap-tonguing benefits from a clear, repeatable progression. Overly aggressive attempts can damage reeds or cause jaw tension. Work in short sets and rotate reeds to avoid overuse.

1. Silent pops: 2 minutes of suction-release pops on the reed without blowing, focusing on consistent sound and tongue placement.
2. Soft air pops: Add a gentle puff of air at the release, aiming for a soft pitched slap on middle-register notes.
3. Single-note repetitions: Play 4 slaps followed by 4 normal tongued notes on the same pitch, alternating textures.
4. Scale fragments: Insert slaps on every other note of a simple scale, keeping tempo slow and tone centered.

Tonguing troubleshooting

Problems with extended tonguing usually involve tongue placement, air support or reed setup. Diagnose by isolating each variable. Record short clips to hear whether issues come from articulation or from tone production in general.

• Symptom: Flutter-tongue stops or becomes uneven. Probable cause: Air too weak or throat too tight. Fix: Increase air speed slightly and relax jaw and neck.
• Symptom: Slap-tongue does not pop. Probable cause: Incomplete suction or tongue too far back. Fix: Move tongue closer to reed tip and ensure full seal before release.
• Symptom: Double tonguing uneven. Probable cause: Back syllable weaker. Fix: Practice “ka” or “ga” alone on mouthpiece until tone matches “ta” or “da.”

Altissimo, harmonics and overblowing: embouchure, airflow and anatomy

Altissimo and harmonic techniques extend the clarinet's range and unlock special color effects. They rely on the instrument's harmonic series, controlled overblowing and precise embouchure adjustments. Understanding how the air column behaves makes high notes more predictable and reduces squeaks and fatigue.

The clarinet overblows at the twelfth because of its cylindrical bore and closed-bottom design. Altissimo notes above written C6 use higher harmonics and special fingerings that stabilize those partials. Small changes in voicing, tongue position and jaw angle can shift which harmonic speaks, so body awareness is important.

Embouchure and voicing for altissimo

Altissimo requires a focused, fast airstream and a firm but not biting embouchure. Think of lifting the tongue slightly toward an “ee” or “ih” vowel while keeping the throat open. The jaw should support the reed from below without clamping. Excess pressure usually causes sharp pitch or squeaks into unwanted partials.

Practice voicing by playing a mid-register note, then slowly raising the tongue position without changing fingers. Notice how the pitch wants to jump to a higher partial. This awareness helps you control which harmonic speaks when using altissimo fingerings.

Harmonic exercises and overblowing drills

Harmonic exercises train your embouchure and air to select specific partials. Start on low notes with simple fingerings, then overblow to higher harmonics using only air and voicing changes. This builds the foundation for reliable altissimo entries and smooth register transitions.

1. Low F harmonic ladder: Finger low F and overblow to the corresponding C and A using increased air speed and higher tongue position, without changing fingers.
2. Long-tone harmonics: Sustain each harmonic for 4 beats, focusing on stable pitch and centered tone.
3. Slurred leaps: Slur between the fundamental and its harmonic, aiming for clean, squeak-free jumps.

Common altissimo fingerings and stability tips

Altissimo fingerings vary by instrument, mouthpiece and reed. Use a reliable fingering chart as a starting point, then adjust based on intonation and response. Focus first on a few target notes, such as written G6, A6 and B-flat6, before expanding the range.

• Choose 2-3 fingerings per pitch: One for intonation, one for response, and possibly one for special color or multiphonics.
• Mark successful fingerings in your music with small diagrams or note names.
• Practice altissimo notes in soft dynamics first, then add crescendos and articulations.

Troubleshooting squeaks and missed altissimo entries

Altissimo squeaks are a major pain point. They usually result from reed-mouthpiece mismatch, excessive embouchure pressure, or unstable voicing. Systematically adjust one variable at a time so you can identify the real cause instead of guessing.

• Symptom: Altissimo squeaks or cracks down. Probable cause: Embouchure too tight or tongue too low. Fix: Slightly relax jaw, raise tongue toward “ee,” and support with faster air.
• Symptom: Note will not speak at all. Probable cause: Reed too hard or tip opening too closed for your air. Fix: Try a slightly softer reed or more open mouthpiece.
• Symptom: Pitch wildly sharp. Probable cause: Over-biting. Fix: Roll lower lip slightly over teeth and think of blowing “through” the note rather than “at” it.

Percussive & textural effects: key clicks, growling, microtones

Percussive and textural extended techniques give clarinetists a wide palette of nontraditional sounds. Key clicks, growling, breath tones and microtones appear frequently in contemporary scores and improvisation. These effects depend on how you use the keys, voice and air, often with little or no normal reed vibration.

Because these sounds can stress pads and mechanisms if overused without care, it is important to balance creative exploration with good maintenance habits. Always listen for mechanical noise, pad slaps and spring behavior as you work on these techniques.

Key clicks and mechanical sounds

Key clicks use the sound of the keys hitting the tone holes or body as a rhythmic or textural element. They can be produced with or without air. Notation often uses “x” noteheads or stems without heads, with instructions such as “key clicks only” or “percussive keys.”

To practice, finger a simple scale without blowing and exaggerate the finger motion so the keys click audibly. Then add a small puff of air to blend the mechanical sound with a faint pitch. Vary dynamics by changing how firmly you close the keys and how much air you add.

Growling and vocal effects

Growling combines a low vocal sound with normal clarinet tone, creating a rough, distorted texture. It is similar to singing-while-playing multiphonics but uses a looser, more guttural vocalization. This effect appears in jazz, rock-influenced works and some contemporary classical pieces.

Start by humming or growling a low pitch while blowing air without the clarinet. Then add the mouthpiece and barrel, keeping the vocal sound relaxed and continuous. Finally, assemble the clarinet and try growling on long tones in the chalumeau register, adjusting vocal pitch to shape the color.

Microtones and quarter tones

Microtones are intervals smaller than a semitone, such as quarter tones. The clarinet is well suited for microtonal work because of its flexible embouchure and many alternate fingerings. Composers often notate quarter tones with arrows or special accidentals indicating pitch raised or lowered by a quarter step.

To produce microtones, use a combination of half-holing, alternate fingerings and subtle embouchure adjustments. For example, to lower a written A by a quarter tone, slightly open the left-hand index finger hole or use an alternate fingering that vents less. Always check with a tuner and record yourself to ensure consistent intonation.

Troubleshooting percussive and textural techniques

Issues with percussive and textural techniques often involve clarity, volume or instrument wear. Address clarity and volume with practice; address wear with maintenance and mindful use. Avoid practicing heavy key clicks for long periods without breaks.

• Symptom: Key clicks too soft. Probable cause: Finger motion too gentle. Fix: Lift fingers slightly higher and close keys with firmer but controlled motion.
• Symptom: Growl overwhelms pitch. Probable cause: Vocal sound too loud relative to air. Fix: Reduce vocal volume and increase clarinet air support.
• Symptom: Microtones inconsistent. Probable cause: Overreliance on embouchure. Fix: Use more stable alternate fingerings and minimal lip adjustments.

Instrument setup & anatomy for extended techniques (reed, mouthpiece, bore, keys)

Instrument setup has a major impact on extended technique success. Reed strength, mouthpiece design, bore dimensions and keywork precision all influence how easily multiphonics, altissimo, slap-tongue and percussive effects respond. Understanding this anatomy helps you choose equipment that supports your goals instead of fighting your technique.

The clarinet's cylindrical bore, register vent and tone-hole layout shape its harmonic behavior. Small changes in mouthpiece facing, reed cut or ligature placement can shift response, stability and color. Extended techniques magnify these differences, so a setup that feels fine for standard playing might struggle with multiphonics or circular breathing.

Reed strength and cut for extended techniques

Reed choice is central for extended techniques. A reed that is too hard can make multiphonics and altissimo unreliable, while a reed that is too soft may collapse under heavy slap-tonguing or loud growling. Many players prefer a slightly softer reed than usual when first learning extended techniques, then adjust as control improves.

French-filed reeds often respond quickly and help with subtle attacks and multiphonics. Unfiled reeds may offer more core for loud altissimo and slap-tongue. Experiment with strengths within a half-strength range (for example, 3.0 to 3.5) and keep notes about which combinations work best for specific techniques.

Mouthpiece and ligature considerations

Mouthpiece tip opening and facing length affect how easily the reed vibrates and how flexible the response feels. A more open tip with a slightly softer reed can aid altissimo and multiphonics by allowing greater vibration at lower pressure. A more closed tip with a slightly harder reed may favor focused, stable standard tone but feel less flexible for extreme effects.

The ligature should hold the reed securely without choking vibration. Metal, fabric and string ligatures can all work; the key is even pressure and consistent placement. Slightly lower ligature placement sometimes increases reed flexibility, which can help with multiphonics and slap-tonguing.

Bore, barrel and keywork anatomy

The clarinet's cylindrical bore and undercut tone holes determine intonation tendencies and harmonic behavior. Barrels with different tapers can subtly change resistance and altissimo stability. A slightly more resistant setup may help control high harmonics, while a freer-blowing setup can ease circular breathing and soft multiphonics.

Keywork precision matters for percussive and microtonal techniques. Even pad seating and balanced spring tension produce clearer key clicks and more predictable half-holing. Leaks or uneven springs can sabotage multiphonics and microtones by destabilizing the air column.

Choosing a setup for your extended technique goals

Match your equipment to your primary extended technique needs. If you focus on contemporary classical repertoire with many multiphonics and microtones, prioritize flexible reeds and a mouthpiece that allows subtle dynamic control. If your work emphasizes loud altissimo and slap-tongue in jazz or amplified settings, choose a setup that supports projection and durability.

• For multiphonics and circular breathing: Slightly softer reed, responsive mouthpiece, comfortable resistance.
• For altissimo and slap-tongue: Balanced reed strength, stable mouthpiece, reliable keywork and pads.
• For percussive effects: Well-regulated mechanism, durable pads, and regular technician checks.

Maintenance steps & troubleshooting for extended-technique playing

Extended techniques place unique stresses on reeds, pads and mechanisms. Regular maintenance keeps your clarinet responsive and prevents small issues from undermining your progress. A simple checklist for daily, weekly and seasonal care is especially important if you practice key clicks, slap-tonguing or heavy growling.

Because many extended techniques use extreme dynamics, unusual fingerings and percussive actions, leaks and misalignments show up quickly as unreliable multiphonics, squeaky altissimo or muffled key clicks. Systematic maintenance and troubleshooting save practice time and reduce frustration.

Daily care for extended-technique players

Daily habits protect your instrument from moisture, reed fatigue and mechanical wear. After sessions that include heavy percussive work or growling, pay extra attention to swabbing and pad checks. Moisture and debris can accumulate faster than in standard practice.

• Swab after every session, including barrel and upper joint, to prevent moisture damage.
• Wipe keys and touchpoints to remove condensation and oils.
• Inspect reed for chips or warping, especially after slap-tonguing drills.

Weekly reed rotation and setup checks

Rotating reeds extends their life and keeps response consistent. Extended techniques can wear reeds faster, especially at the tip and rails. A simple rotation system and weekly setup check prevent sudden failures in performance or lessons.

1. Keep 4-6 reeds in active rotation, labeled by date or number.
2. Play each reed briefly every few days to monitor response for multiphonics and altissimo.
3. Retire reeds that chip, warp or lose clarity on extended techniques, even if they still work for basic playing.

Monthly leak checks and lubrication

Leaks and sticky keys undermine extended techniques more than standard playing. Monthly checks catch problems early. You can do basic tests yourself, but schedule professional service at least annually or when issues persist.

• Use a leak light or feel test to check for leaks around critical tone holes, especially in the upper joint.
• Apply key oil sparingly to pivot points if you are trained to do so, or ask a technician.
• Check corks and tenons for dryness or compression, which can affect alignment and tuning.

Extended-technique troubleshooting: symptom to fix

When extended techniques suddenly stop working, rule out equipment issues before blaming your technique. A small leak or reed change can completely alter multiphonic fingerings or altissimo response. Use a simple symptom-cause-fix approach.

• Symptom: Multiphonics that used to work are unstable. Probable cause: Reed change or new leak. Fix: Test with a different reed and perform a quick leak check.
• Symptom: Key clicks sound muffled. Probable cause: Soft or swollen pads. Fix: Let the instrument dry fully and consult a technician if problem persists.
• Symptom: Circular breathing tone breaks at the switch. Probable cause: Fatigue or reed too resistant. Fix: Shorten practice cycles and try a slightly softer reed.

Historical context and the Martin Freres legacy (18th-20th century evolution)

Extended techniques might feel modern, but their roots lie in the clarinet's 18th-century evolution and later experiments in the 19th and 20th centuries. Early clarinets already exploited overblowing, cross-fingerings and color contrasts that foreshadowed contemporary multiphonics and microtones. As the instrument developed, so did the appetite for new sounds.

By the late 19th century, composers such as Richard Strauss and Claude Debussy were pushing clarinet range and color. In the 20th century, figures like Igor Stravinsky, Olivier Messiaen and Luciano Berio encouraged performers to explore extreme dynamics, altissimo and unusual articulations. This environment paved the way for systematic extended technique research and notation.

Throughout the 20th century, clarinetists and composers documented new sounds in method books and treatises. Experimental works from the 1960s onward integrated circular breathing, key clicks, slap-tonguing and vocalization directly into scores. The clarinet's flexible acoustics and evolving keywork made it a favorite instrument for avant-garde exploration, connecting modern practice to a long heritage of innovation.

Practice routines, repertoire applications and measurable player outcomes

Extended techniques become reliable only when integrated into structured practice. Short, focused sessions are more effective than occasional long experiments. Clear goals and measurable outcomes help you track progress and apply new skills to real repertoire, auditions and improvisation.

A weekly plan should balance technique drills, musical application and maintenance. Rotate focus among multiphonics, circular breathing, tonguing and altissimo so you build a broad skill set without overloading your embouchure or equipment.

Sample weekly practice routine for extended techniques

This 6-day plan fits into a 60-minute daily practice schedule. Adjust times based on your level and repertoire demands. Always start with a short warm-up of standard tone and articulation before tackling extended work.

• Day 1: 10 minutes multiphonics, 10 minutes flutter- and slap-tongue, 5 minutes altissimo harmonics.
• Day 2: 10 minutes circular breathing drills, 10 minutes microtones and half-holing, 5 minutes key clicks.
• Day 3: 10 minutes altissimo scales, 10 minutes singing-while-playing multiphonics, 5 minutes growling textures.
• Day 4: Repeat Day 1 with different fingerings and excerpts.
• Day 5: Repeat Day 2, integrate into short etudes or improvisations.
• Day 6: Repertoire integration: 20-30 minutes applying techniques in actual pieces.

Repertoire and improvisation applications

Extended techniques appear in contemporary solo works, chamber music, jazz and free improvisation. Use etudes and short excerpts to bridge the gap between drills and full pieces. Many players also create their own exercises by re-composing fragments from existing repertoire with added multiphonics or microtones.

In improvisation, extended techniques can function as timbral variations, rhythmic layers or dramatic effects. For example, alternate between normal tone and growling on a repeated riff, or insert key-click ostinatos under a sustained multiphonic drone. The goal is musical integration, not just demonstration of special effects.

Measurable outcomes for extended-technique progress

Concrete benchmarks help you evaluate your development and prepare for auditions or performances that require extended techniques. Track these outcomes over weeks and months, and adjust your practice routine based on which goals lag behind.

• Multiphonics: Produce 3-5 stable multiphonics with consistent pitch and dynamic control for at least 4 seconds each.
• Circular breathing: Sustain a continuous tone for 30-60 seconds with minimal audible transition.
• Slap-tongue: Execute 8-12 clean slap-tongue attacks in a row at moderate tempo on a single pitch.
• Altissimo: Play 2-3 target altissimo notes with reliable response and accurate intonation in both soft and loud dynamics.

Musical outcomes include access to a wider range of contemporary repertoire, increased versatility in ensembles, and distinctive audition materials that showcase your command of modern clarinet language. Teachers can use these benchmarks to design curricula and evaluate student progress objectively.

Resources, notation tips and further learning (audio/video/fingering charts)

Reliable resources make learning extended techniques more efficient. Fingering charts, notation guides, recordings and videos provide concrete examples and references that support your practice. When possible, consult multiple sources, since fingerings and notation conventions can vary by region and composer.

Many contemporary clarinet methods include dedicated sections on multiphonics, microtones and altissimo. Academic articles and dissertations often provide detailed acoustic analysis and alternative fingering systems. Listening to recordings by specialist performers helps you internalize target sounds and musical contexts.

Notation tips for performers and teachers

Understanding notation conventions reduces confusion in rehearsal and lessons. Extended techniques often use special noteheads, text instructions and symbols. When in doubt, consult the composer's legend or performance notes, and do not hesitate to contact living composers for clarification.

• Multiphonics: Dyads or chord-like noteheads, sometimes with specific fingering diagrams above the staff.
• Circular breathing: Horizontal brackets or infinity symbols with text such as “circular breathe.”
• Slap-tongue: “Slap” markings, accent-like symbols, or noteheads with small “x” through the stem.
• Key clicks: “x” noteheads or stem-only notation with text “key clicks” or “percussive keys.”
• Microtones: Arrows or special accidentals indicating quarter-tone up or down.

Using audio, video and fingering charts effectively

Audio and video examples accelerate learning by giving you clear sonic targets and visual models of embouchure and fingerings. Combine passive listening with active imitation. Pause frequently, match short phrases or sounds, and record your attempts for comparison.

Fingering charts for multiphonics, altissimo and microtones are starting points, not absolute rules. Test each fingering on your own instrument, adjust for intonation and response, and mark your personal favorites. Teachers can compile custom charts for students based on shared setups, helping standardize results in studio settings.

Planning your next steps in extended techniques

After establishing basic control of a few techniques, choose a short piece or etude that uses them musically. Work with a teacher or ensemble to integrate extended sounds into phrasing, dynamics and form. Over time, extended techniques should feel like natural extensions of your musical vocabulary, not isolated tricks.

FAQ

What is clarinet extended techniques?

Clarinet extended techniques are nontraditional ways of producing sound, such as multiphonics, circular breathing, slap- and flutter-tonguing, key clicks, growling, microtones and extreme altissimo. They expand the instrument's expressive range beyond standard tone and articulation, and are used in contemporary classical music, jazz, improvisation and experimental genres.

How do I practice circular breathing step-by-step?

Start without the clarinet by filling your cheeks, squeezing air out with cheek muscles while inhaling through your nose, and repeating in short cycles. Then practice blowing bubbles through a straw while circular breathing. Finally, transfer the motion to soft long tones on the clarinet, aiming for 1-2 second cheek-squeeze cycles and gradually lengthening the sustained note.

Which fingerings help produce stable multiphonics?

Stable multiphonics often use special fingerings that partially vent the air column, such as low F with added right-hand E/B key and half-holed left index, low G with side F-sharp and slight register vent, or throat A with added side keys and half-holing. Use a reliable multiphonic fingering chart as a starting point, then test and adjust on your own instrument.

Why does my altissimo squeak and how can I fix it?

Altissimo squeaks usually come from embouchure that is too tight, tongue position that is too low, or a reed-mouthpiece setup that resists high harmonics. To fix this, slightly relax your jaw, raise your tongue toward an “ee” vowel, support with faster air, and consider trying a slightly softer reed or more open mouthpiece if response remains unreliable.

Do extended techniques damage my instrument or reed faster?

Extended techniques can wear reeds and pads faster, especially slap-tonguing, heavy key clicks and intense growling. With good habits, they do not inherently damage the instrument. Rotate reeds, swab and dry the clarinet after practice, limit very aggressive percussive work, and schedule regular technician checks to keep keywork and pads in good condition.
