Clarinet alternate fingerings are alternative key and pad combinations that produce the same pitch but improve transitions, intonation, or tone color. Use them to smooth technical passages, execute trills effectively, and fix tuning issues, such as using first+second+fifth fingers for a C to D trill or the side F/C key for low C/G transitions.
Understanding Clarinet Alternate Fingerings: What and Why
Clarinet alternate fingerings are different finger combinations that produce the same written pitch as the standard fingering. They change which keys and pads vibrate or vent, which affects response, tuning, and tone color. Skilled players keep several options ready for each problem note so they can choose the best solution for speed, intonation, or musical color.
Alternate fingerings matter most in three situations: fast technical passages, trills and tremolos, and intonation or tone problems. A passage that feels impossible with standard fingerings often becomes smooth when you change just one or two notes. Alternates also let you avoid large finger jumps that cause bumps or missed notes at high tempos.
Trills and tremolos rely heavily on alternates. Many written trills are awkward or nearly unplayable with basic fingerings. Using side keys, the alternate F/C key, or partial right-hand combinations can turn a clumsy shake into a clean, even trill. Alternates also let you match pitch with piano, strings, or other winds more precisely.
Intonation is another core reason to learn alternates. Some clarinet notes are naturally sharp or flat because of acoustics and bore design. Alternate fingerings can lengthen or shorten the air column or change venting to bring those notes into tune. Players often keep a small personal list of “tuning alternates” for their specific instrument.
Most intermediate clarinetists benefit from learning at least 15 to 25 core alternate fingerings and trill patterns that they can recall instantly in performance.
Alternate fingerings also expand tone color. For example, a throat B flat can sound brighter with the side key or darker with a resonance fingering. Advanced players choose alternates not only for ease but for phrasing, blending with section sound, and matching historical style in orchestral or chamber music.
Types of Trills and Common Trill Fingerings (whole-tone, half-tone, chromatic)
Clarinet trills fall into three main types: whole tone, half tone, and chromatic trills that cross larger intervals. Each type has favored alternate fingerings that keep motion small and even. Understanding which fingers should move and which should stay stable is the key to reliable, fast trills.
Whole tone trills move up a whole step, such as written C to D or F to G. These often use combinations of left-hand main fingers with right-hand helper keys. For example, a common C to D trill uses left-hand first and second fingers plus a partial touch of the right-hand B key to minimize motion and keep the hand relaxed.
Half tone trills move by a semitone, such as E to F or B to C. Many of these use side keys or small finger lifts instead of full finger changes. For instance, a written E to F trill in the staff often uses the E standard fingering with a right-hand side key, avoiding a full left-hand motion that would slow the trill and risk squeaks.
Chromatic trills or tremolos can span larger intervals, often in modern or virtuosic repertoire. These might connect notes like F sharp to G sharp or B to C sharp repeatedly. Players usually combine register key tricks, right-hand alternates, and side keys to keep the motion compact. Some of these patterns are very instrument specific and must be tested carefully.
For each trill, you want two things: minimal finger travel and stable anchor fingers. The best trill fingering usually keeps at least two or three fingers down as a base while one or two fingers move quickly. If both hands must jump, the trill will be uneven and likely to crack or miss notes at tempo.
A practical goal is to master clean, even trills at quarter note = 120 with at least 8 to 10 oscillations per beat for core intervals like C-D, D-E, and E-F.
Because clarinet systems and hand sizes vary, every player should test several trill options with a tuner and metronome. Mark the best choices directly in your part. Over time, you will build a personal trill vocabulary that you can apply quickly in new pieces without re-inventing solutions every time.
Instrument Anatomy: The Alternate F/C Key and Side Keys
Understanding key anatomy is important for using alternate fingerings correctly. The alternate F/C key and side keys are designed to give you extra options beyond the main finger holes. On most intermediate and professional clarinets, these keys sit where your fingers can reach them without major hand shifts.
The alternate F/C key is usually located on the right-hand side of the lower joint, near the right-hand ring finger. It connects to the same tone hole as the standard low F and C but through a different lever. This lets you choose whether the right-hand ring finger or another finger operates that pad, which can simplify many low-register patterns.
Side keys sit on the upper joint and are operated by the right-hand index finger or sometimes the left-hand index finger sliding slightly. These keys control small vent holes that adjust pitch and facilitate certain trills, such as E to F, F to G, and throat note alternates. They are critical for fast chromatic work and smooth trills in the clarion register.
The right-hand B key, sometimes called the side B or trill key, is another important part of the alternate system. It is typically pressed by the right-hand index finger on the side of the instrument. In patterns like C to D trills or certain clarion alternates, this key lets you add or remove a small vent without lifting large fingers.
Left-hand and right-hand interactions matter a lot for alternates. Many useful fingerings combine stable left-hand main fingers with right-hand side or trill keys. For example, you might keep left-hand first and second fingers down while the right-hand index taps a side key. This division of labor keeps the hand balanced and reduces strain.
When you study a fingering or trills chart, picture the clarinet in your hands. Imagine which finger touches each key and how far it must travel. If a suggested alternate requires a big stretch or awkward twist for your hand, look for another option that uses the same pitch but a more natural motion on your specific instrument.
Field note: Martin Freres archival catalogs from the early 20th century show how the addition of alternate F/C keys and refined side key placement on intermediate and professional clarinets was promoted as a major advance in playability and intonation control for advancing students.
Common Alternate Fingering Patterns and Specific Examples
Most clarinetists rely on a core set of alternate fingering patterns that solve recurring problems. These patterns fall into groups: throat note alternates, clarion register alternates, low-register alternates using the F/C key, and specialized trills. Learning these by pattern, not just note by note, speeds up your decision making in real music.
Throat B flat (written B flat just above open G) has several alternates. The standard A plus register key plus right-hand first finger can be sharp and stuffy. Many players use the side B flat key or an A fingering with a resonance fingering such as adding left-hand third finger. These alternates improve tone and pitch, especially in soft passages.
Throat A and G sharp also benefit from resonance alternates. For A, adding left-hand third finger or right-hand first finger can stabilize pitch and tone. For G sharp, combining the normal fingering with a right-hand finger down often darkens the sound and helps match neighboring clarion notes. These subtle changes are important in orchestral and chamber music.
In the clarion register, written B to C and C to D often use alternates for trills and fast runs. A common B to C trill uses the normal B fingering plus a side key or trill key instead of a full finger change. For C to D, many players keep left-hand first and second fingers down and tap the right-hand B key lightly to avoid a full left-hand lift.
Low-register alternates center on the F/C key. For example, in a passage moving from low C to low G, using the alternate F/C key can keep the right-hand ring finger stable while another finger moves. This reduces the risk of leaks and bumps. Similarly, in patterns like low E to F to G, the alternate F/C key can simplify the motion sequence.
Some alternates are primarily intonation tools. Written E in the staff might be sharp on some clarinets with the standard fingering. Adding a right-hand finger, such as the ring finger, can lower the pitch slightly. Written F sharp in the clarion register can sometimes be tamed by adding a low right-hand finger to darken and stabilize the sound.
Specialized trills, such as written F to G or G to A in the clarion register, often use side keys. For example, an F to G trill can be done by holding the F fingering and tapping a side key instead of fully changing to the G fingering. This keeps the hand relaxed and allows very fast, even oscillations without embouchure strain.
Many professional players regularly use at least 5 to 8 different alternates just for the throat tones alone, choosing among them based on dynamic, register, and surrounding notes.
As you learn these patterns, write them directly into your music where needed. Use small noteheads or symbols above the staff to remind yourself which alternate to use. Over time, these choices become automatic, and you will instinctively reach for the best fingering in each musical context.
Building and Reading a Clarinet Trills Chart
A clarinet trills chart is a visual map that shows the best fingerings for common trills and tremolos across the instrument. Instead of guessing in the middle of practice, you can consult the chart to find proven solutions. Learning how to read and customize such a chart saves time and prevents bad habits.
Most trills charts are organized by written note and interval. One axis lists the starting note, such as written C, D, or E, and the other axis lists the target trill note, such as D, E flat, or F. Each cell shows a recommended fingering pair or a description of which key to tap, such as “add right-hand side key” or “use alternate F/C key.”
When you read a chart, focus on which fingers move, not just which keys are named. Mark which fingers stay down as anchors. For example, if the chart says to trill from C to D by adding the right-hand B key, you know that the left-hand fingers remain stable while the right-hand index moves. This helps you visualize the motion before trying it.
Building your own chart can be even more powerful. Start with a printed or digital base chart from a reliable source, then test each trill on your own clarinet. Use a tuner and metronome. If a suggested fingering is out of tune or feels awkward, note an alternative that works better for you and write it into your personal chart.
Include notes about context on your chart. Some alternates are ideal for soft dynamics but unstable when loud. Others are perfect for fast tempos but slightly out of tune when held. You might mark “best for pp” or “only for fast trill” next to specific entries. This turns your chart into a practical performance tool, not just a static reference.
Digital charts can be stored on a tablet or laptop and updated over time. You can add images or diagrams showing finger positions, highlight problem areas, and group trills by key signature or repertoire. For example, you might create a special section for trills commonly found in Mozart, Weber, or Debussy clarinet works.
Teachers can build studio charts that reflect the instruments their students use. A chart that works well on one brand or bore design may need small adjustments on another. Encourage students to compare the studio chart with their own experiments, so they learn to think critically about fingerings instead of memorizing blindly.
Practice Exercises and Routines (scales, chromatic trills, mirror work)
Effective practice routines turn alternate fingerings from theoretical knowledge into reliable reflexes. The goal is to integrate alternates into scales, arpeggios, and real musical phrases so they feel as natural as standard fingerings. Structured drills with a metronome and tuner help you track progress objectively.
Start with slow scale work that includes planned alternates. For example, play a B flat major scale in the staff and decide in advance which throat note alternates you will use. Practice at a slow tempo, such as quarter note = 60, focusing on smooth finger motion and even tone. Gradually increase speed while keeping the same alternates.
Chromatic scales are ideal for trill preparation. Play a one-octave chromatic scale using standard fingerings, then repeat using alternates where possible, such as side keys for E to F or F to G transitions. This helps your fingers learn the geography of the side keys and the alternate F/C key in a predictable pattern.
Dedicated trill drills are important. Choose one trill, such as C to D, and practice it in rhythmic patterns: two notes per beat, then four, then eight. Start slowly, focusing on relaxed fingers and stable embouchure. Use a metronome and increase tempo only when the trill sounds even and clean, with no extra notes or squeaks.
Mirror work helps you monitor finger height and tension. Practice in front of a mirror and watch that your fingers stay close to the keys, especially when using side keys and the F/C key. High finger lifts slow you down and cause uneven trills. Aim for minimal motion that still seals the keys completely.
Integrate alternates into real repertoire excerpts. Take a difficult passage from a solo, etude, or orchestral part and mark all potential alternates. Practice the passage slowly with each option, then choose the one that gives the best combination of speed, tone, and intonation. Record yourself to compare results objectively.
Finally, schedule short daily sessions focused only on alternates and trills. Even 5 to 10 minutes of targeted work can produce big gains over a few weeks. Rotate focus: one day on throat alternates, another on clarion trills, another on low-register work with the F/C key. Consistency matters more than long, infrequent sessions.
Troubleshooting: Squeaks, Intonation and Uneven Trills
When alternate fingerings misbehave, the symptoms usually fall into three categories: squeaks, tuning problems, and uneven or slow trills. A step-by-step troubleshooting process helps you isolate whether the issue comes from fingerings, embouchure, air support, or mechanical problems with the instrument.
If a trill squeaks or cracks, first slow it down. Play the two notes alternately in quarter notes, listening for clean attacks and stable tone. Check that your fingers fully cover the tone holes and that side keys are pressed firmly but not slammed. Watch in a mirror to ensure fingers are not lifting too high between notes.
Next, test the same two notes using standard fingerings, without the alternate. If they still squeak, the issue may be embouchure or air support rather than the alternate fingering. Focus on steady air, relaxed jaw, and a firm but not biting embouchure. Once the standard pair is stable, reintroduce the alternate trill motion.
For intonation problems, use a tuner to compare standard and alternate fingerings for the same note. Sustain each note for at least four beats and note whether the alternate is sharp or flat compared to the standard. Some alternates are intentionally slightly off and should only be used in fast passages, not for long held notes.
If a note is consistently out of tune with both standard and alternate fingerings, check for mechanical issues. A leaking pad, bent key, or misaligned ring can affect pitch and response. Test the note at different dynamics and with different finger pressures. If the problem persists, consult a qualified repair technician.
Uneven trills often result from unbalanced finger motion. One finger may be traveling farther or faster than the other. Practice the trill motion in slow motion, exaggerating the smaller movement and minimizing the larger one. Focus on keeping both fingers close to the keys and moving with the same rhythm and amplitude.
Room acoustics can also affect how alternates sound. A bright, reflective room may exaggerate sharpness or harshness in certain fingerings, while a dry room may hide subtle intonation differences. When possible, test your alternates in the same type of space where you will perform, such as a concert hall or band room.
Maintenance and Key Care for Reliable Alternate Fingerings
Reliable alternate fingerings depend on responsive keys and well-sealing pads. Even a small leak or sluggish spring can ruin a trill or make an alternate unusable. Simple, regular maintenance keeps the alternate F/C key, side keys, and trill keys working smoothly so your technique is not fighting the instrument.
After every practice session, swab the clarinet thoroughly to remove moisture from the bore and pads. Pay special attention to the lower joint, where the F/C key pad sits, and to the upper joint side key area. Moisture left on pads can cause swelling, sticking, or slow response, which directly affects alternate fingerings.
Inspect pads and key motion weekly. Gently press each side key and the F/C key while watching the pad close. Look for uneven closure, slow return, or any sign of sticking. If a pad hesitates or does not seal fully, it will compromise trills and alternates that rely on that key. A small amount of pad cleaning paper can sometimes help with minor stickiness.
Key rods and linkages for side keys and the F/C key should be lightly lubricated at regular intervals, typically every 6 to 12 months depending on playing frequency. This work is best done by a repair technician, who can apply the correct oil sparingly and check for wear. Over-oiling can attract dirt and cause more problems.
Key height and spring tension affect how alternates feel. If a side key sits too high or too low, your finger must travel farther or may not seal the pad properly. If a spring is too weak, the key may not return quickly enough for fast trills. Ask a technician to check and adjust these settings if alternates feel sluggish or inconsistent.
Store the clarinet in its case when not in use, and avoid placing heavy objects on top of the case. Pressure can bend keys slightly, especially delicate side keys and the F/C key mechanism. Even a small bend can change pad alignment and cause leaks that only show up in certain alternates or trills.
If you notice sudden changes in how an alternate responds, such as a trill that used to be easy now feeling resistant, schedule a checkup. Describe the specific fingerings and notes involved so the technician can test those areas. Regular professional maintenance, at least once a year for active players, keeps your alternate system dependable.
Historical Context and Martin Freres' Role in Clarinet Key Design
Alternate fingerings on the clarinet grew out of centuries of key design evolution. Early clarinets had few keys and limited options for trills and chromatic notes. As music by composers like Mozart, Weber, and later Brahms demanded more agility and color, makers added keys to give players alternate routes between pitches.
The development of the Boehm system and its adaptations for clarinet standardized many modern key placements, including side keys and trill keys. These additions allowed for smoother chromatic scales, more reliable trills, and better intonation across the instrument. The alternate F/C key became a hallmark of more advanced instruments, aimed at serious students and professionals.
Martin Freres, active in the late 19th and early 20th centuries, contributed to this evolution by offering clarinets with refined keywork that emphasized playability and intonation. Archival catalogs highlight models with improved side key placement and alternate F/C keys on intermediate and professional instruments, marketed as important for advanced technique and orchestral playing.
As clarinet pedagogy matured, method books by authors such as Klose and Baermann began to include discussions of alternate fingerings and trills. These resources helped standardize which alternates were considered reliable and musical. Over time, a shared vocabulary of alternates emerged among teachers and performers, though individual preferences still vary.
Today, modern clarinet design continues to refine key shapes, spring tensions, and ergonomics to support alternate fingerings. Makers experiment with ring placement, vent sizes, and lever geometry to improve the feel and response of side keys and the F/C key. Serious players benefit from this history every time they choose an alternate that simply works.
Expected Player Outcomes and How to Measure Progress
Learning clarinet alternate fingerings should lead to clear, measurable improvements in your playing. You can track progress in several areas: technical speed, trill quality, intonation control, tone color flexibility, and confidence in difficult passages. Setting specific goals and metrics keeps your practice focused and motivating.
For technical speed, choose a scale or etude that uses several alternates and record your top clean tempo. Aim to increase this tempo gradually over weeks, while keeping tone and rhythm steady. A realistic target might be to raise your comfortable tempo by 10 to 20 beats per minute over a month of consistent practice.
Trill quality can be measured by evenness and clarity at a given tempo. Use a metronome and count how many oscillations you can play per beat while keeping the trill smooth. Track this number in a practice journal for key trills like C-D, D-E, and E-F. As your alternates become more automatic, you should see both speed and control improve.
Intonation control is best monitored with a tuner and recordings. Compare standard and alternate fingerings for problem notes and note how many cents each option deviates from center. Over time, you should learn which alternates reliably bring notes closer to pitch and how to adjust your embouchure and air to fine tune them in context.
Tone color flexibility shows up in your ability to match sound across registers and dynamics. Record yourself playing the same phrase using different alternates for throat tones or clarion notes. Listen for smoothness of color and the absence of sudden brightness or dullness. Improved control here translates directly into more expressive phrasing.
Confidence in difficult passages is perhaps the most satisfying outcome. Pieces that once felt risky because of awkward fingerings or unreliable trills should start to feel secure. You will notice fewer missed notes in performance and less tension in your hands. Teachers often see this in students as a shift from “hoping” a passage works to knowing it will.
Finally, evaluate your progress in real musical contexts. Perform for peers, teachers, or in ensembles and pay attention to comments about tone, tuning, and clarity. When conductors stop mentioning certain problem spots, it is a strong sign that your alternate fingering work is paying off in practical, musical ways.

FAQ
What is clarinet alternate fingerings?
Clarinet alternate fingerings are different combinations of keys and pads that produce the same written pitch as the standard fingering. Players use them to improve technical ease, execute trills more cleanly, adjust intonation, and shape tone color in specific musical contexts.
How do I choose the right alternate fingering for a trill or fast passage?
Choose the alternate that keeps finger motion smallest and most balanced while staying in tune. Test several options from a reliable trills chart, practice each slowly with a tuner and metronome, then select the one that feels secure and sounds clean at your target tempo.
When and how should I use the alternate F/C key?
Use the alternate F/C key in low-register passages where the standard F or C fingering creates awkward finger jumps or instability. It is especially helpful in patterns like low C to G or E to F to G, where keeping the right-hand ring finger stable simplifies motion and improves reliability.
What are common practice routines to master trills using alternate fingerings?
Common routines include slow trill drills with rhythmic patterns, chromatic scales using side-key alternates, and focused work on one or two trills per session. Practice with a metronome, start at a comfortable tempo, and increase speed only when the trill remains even, clean, and in tune.
Why does a note sound out of tune with standard fingering and how can an alternate fix it?
Some clarinet notes are acoustically sharp or flat due to bore design and venting. An alternate fingering changes the effective length or vent pattern of the air column, which can raise or lower the pitch. Testing alternates with a tuner helps you find options that bring specific notes closer to center.
