What are clarinet overtones and how do you start? Clarinet overtones are the higher harmonic pitches that occur above a played fundamental. To start producing them: 1) warm up with long tones in the chalumeau register on low Bb or low E, 2) stabilize embouchure and air support, 3) sustain a low note and gently adjust air speed and embouchure until higher partials sound.
What are Clarinet Overtones? (acoustics & frequency multiples)
Clarinet overtones are higher pitches that vibrate above a fundamental note as whole-number multiples of its frequency. On clarinet, these overtones follow an odd-harmonic pattern because of the closed cylindrical bore. That pattern explains why low E can jump to B, F sharp and higher, and why overtone work feels different from flute or saxophone.
When you play low Bb or low E, you mostly hear the fundamental, but your air column also vibrates at 3x, 5x, 7x and higher frequency components. Good clarinet tone lets more of these upper harmonics ring clearly. Overtone practice teaches you to control which partial dominates without changing the written fingering.
The clarinet behaves acoustically like a cylindrical tube closed at one end by the reed. That design favors odd-numbered harmonics: 1st, 3rd, 5th, 7th, and so on. This is why the register key jumps you roughly a twelfth instead of an octave. Understanding that pattern helps you predict which overtones are realistic to target on each low note.
Overtones are not just a theory topic. They directly affect projection, color and pitch stability in orchestral and band playing. When you learn to hear and control them, you can match your sound more closely to players from ensembles like the Berlin Philharmonic or the Chicago Symphony, where harmonic richness is a key part of the section sound.
Why Overtones Matter for Tone, Intonation and Expression
Clarinet overtones matter because they shape how your sound carries, blends and responds. A tone with strong, balanced overtones projects easily without extra effort. That is why some players seem to play loudly while barely moving, while others work hard and still get a dull sound. Overtone control is the hidden difference.
For intonation, overtones act like internal tuning guides. When you practice matching a higher overtone to a normally fingered note, you learn how much to adjust voicing, embouchure and air to center the pitch. This skill translates directly to cleaner twelfths, better throat-tone tuning and more reliable altissimo entries.
Overtones also expand your expressive palette. By slightly changing tongue position and air speed, you can emphasize or soften certain harmonics. That lets you create darker, covered colors for Brahms or more brilliant, ringing colors for Copland or Bernstein without changing equipment. The same overtone awareness helps you shape vibrato on styles that call for it.
For advanced students, overtone fluency supports extended techniques like multiphonics and quarter-tone shading. Even if you never use those effects in performance, the underlying control over voicing and air makes normal repertoire feel easier and more predictable under pressure.
Anatomy of the Clarinet and How It Produces Overtones
The clarinet produces overtones through the interaction of reed, mouthpiece, bore and tone holes. The reed acts as a pressure-controlled valve, chopping the air into pulses. Those pulses travel into the cylindrical bore, reflect at the bell and tone holes, and set up standing waves that define the fundamental and its harmonics.
The cylindrical bore and closed-end behavior at the mouthpiece favor odd harmonics. That is why the clarinet overblows at the 12th instead of the octave, unlike the flute or oboe. The register key vents the air column near a pressure node of the 3rd harmonic, weakening the fundamental and allowing the higher partial to dominate.
The mouthpiece and reed combination shape how easily certain overtones respond. A more open tip and softer reed can make lower overtones easier but may destabilize higher partials. A more resistant setup can clarify higher overtones but demands stronger air support. Finding a balanced setup is important before serious overtone practice.
Body design matters too. The placement and size of tone holes, the taper of the upper joint, and the shape of the bell all influence harmonic balance. This is one reason different clarinet makes and models have distinct overtone profiles and why some instruments feel naturally “ringier” in the clarion register.
The chalumeau register, especially low Bb and low E, is the ideal starting point for overtone work because these notes sit on long, stable air columns with few open tone holes. That stability makes it easier to isolate and control higher partials without the interference of complex venting patterns found in higher notes.
Warm-ups and Pre-exercise Checklist (instrument & player)
Before overtone work, both clarinet and player must be stable. Start by assembling the instrument carefully and warming it for at least 5 minutes with gentle playing. Cold clarinets respond unpredictably, especially in the chalumeau register, which makes overtone training frustrating and inconsistent.
Check that all pads seal, particularly around low E, F and F sharp. Lightly press each key while blowing air to feel for leaks. Poor pad seal weakens the fundamental and makes overtones harder to control. If low E or low F feels stuffy or unreliable, have a technician check key height and regulation.
Inspect your reed for chips, warping or waterlogging. Use a reed that is fully broken in but not worn out. The tip should respond easily to soft attacks without collapsing at louder dynamics. Align the reed evenly on the mouthpiece so that the tip follows the curve and both rails show a thin, even border.
Warm up your embouchure and air with long tones in the chalumeau register. Hold low E, F and G for 8 to 12 seconds each, focusing on a steady, centered sound with no wobble. Add simple crescendo and decrescendo patterns to test control. Do not move on until your tone feels predictable and squeak free.
Finally, check posture and breathing. Stand or sit tall, with relaxed shoulders and a natural curve in the lower back. Inhale silently through the mouth, feeling expansion in the ribs and abdomen. Overtone work demands fast, steady air, so any tension in the throat or chest will show up immediately as instability.
Core Overtone Exercises – Beginner to Advanced (start on low Bb / low E)
Start overtone practice on low E and low Bb because these notes offer the most stable fundamentals and clearest partials. Use a tuner and, if possible, a drone or piano to check pitch. Always begin softly, then increase air speed while keeping embouchure steady. The goal is control, not volume.
Beginner: Discovering the 2nd and 3rd partials
Begin with low E. Finger low E normally, then play it as a long tone. Without changing fingers, gradually increase air speed and slightly raise the back of your tongue, as if saying “ee”. Aim to let the sound jump to B above middle C, the 3rd harmonic. Hold that B as steadily as possible.
Alternate between the fundamental low E and the overtone B. Play 4 beats of E, then 4 beats of B, always with the same fingering. Rest briefly between attempts. Once B feels reliable, repeat the process on low F to reach C, and on low D to reach A. Keep the dynamic around mezzo forte to avoid forcing.
Next, explore low Bb. Finger low Bb and try to overblow to F in the staff. Use the same voicing motion and air increase. Some players find low Bb more resistant, so be patient. If it does not respond, return to low E until your control improves, then revisit low Bb every few days.
Intermediate: Matching overtones to normal fingerings
Once you can reliably produce the 3rd partials, begin matching them to normally fingered notes. For example, play B in the staff with standard fingering, then immediately play the same B as an overtone from low E. Listen for pitch and color. Adjust voicing until both versions match as closely as possible.
Create small patterns: B (normal) – B (overtone from E) – B (normal) – rest. Repeat 4 to 6 times. Do the same with C from low F, A from low D, and F from low Bb. This exercise connects overtone awareness directly to your everyday fingerings and improves intonation consistency.
Extend the range by aiming for the 5th harmonic. From low E, try to reach F sharp above the staff. This will require faster air and a higher tongue position, but embouchure pressure should stay stable. Do not bite. If the sound thins or becomes sharp, back off slightly and refocus on air support.
Advanced: Flexibility, patterns and altissimo preparation
For advanced players, practice rapid switches between partials on one fingering. On low E, alternate E – B – E – B in eighth notes at a slow tempo, then gradually increase speed. Keep the tone centered and avoid jaw movement. The change should come almost entirely from tongue position and air speed.
Next, add the 5th partial: E – B – F sharp – B – E in a slow, even pattern. Use a metronome and record yourself to check stability. If any note speaks late or cracks, slow down and reduce dynamic. The goal is even response across all partials, not maximum range.
Connect overtone work to altissimo by matching overtone-produced notes to high-register fingerings. For example, match the F sharp overtone from low E to a normally fingered altissimo F sharp. This builds a direct link between your voicing for overtones and the voicing needed for clean altissimo attacks.
Overtone Fingering Charts and How to Read Them
Overtone fingering charts show which fundamentals can produce specific higher partials. Typically, the chart lists the written low note on the left, with columns for 3rd, 5th, 7th and higher harmonics. Each cell indicates the target pitch you can aim for without changing the basic fingering.
For example, a chart might show low E with B in the 3rd harmonic column and F sharp in the 5th. Low F might show C and G, and low D might show A and E. These relationships come directly from the clarinet's acoustic behavior as a closed cylindrical tube favoring odd harmonics.
Some charts include suggested voicing cues or dynamic ranges for each overtone. Treat these as starting points, not strict rules. Your mouthpiece, reed and clarinet combination may respond slightly differently, especially if you play on a larger bore or a different cut of reed than the chart's author.
When using an overtone chart, practice one fundamental at a time. Circle the partials you can already produce and mark those that feel unstable. Revisit the unstable ones for short, focused sessions rather than forcing them for long periods. Over time, your chart becomes a record of your progress.
Teachers can use overtone charts to design custom exercises. For instance, you might create a pattern that moves through the 3rd partials of low E, F, G and A, then returns through their fundamentals. This structured approach helps students see and hear the harmonic relationships more clearly.
Troubleshooting Common Problems (embouchure, air support, squeaks)
Many players struggle with squeaks, unstable partials or notes that will not speak at all. Start troubleshooting with a “no squeaks allowed” baseline: if you cannot play long tones on low E, F and G for 8 seconds without squeaks, fix that first before heavy overtone work.
Step 1: Check reed and mouthpiece. If the reed is too soft, it may collapse under the increased air needed for overtones. If it is too hard, you may bite to make it respond. Try a reed strength that lets you play mezzo forte in all registers without strain. Confirm that the reed is centered and not leaking at the tip.
Step 2: Adjust embouchure. If overtones are sharp or thin, you may be biting. Think of firm corners and a cushioned top lip, with the lower lip acting as a stable pad, not a clamp. If the sound is fuzzy or unfocused, increase firmness slightly at the corners while keeping the jaw relaxed.
Step 3: Vary air support. Overtones need faster, not necessarily louder, air. Imagine blowing warm air through a narrow straw. If the sound drops back to the fundamental unexpectedly, your air may be slowing down. Practice crescendo-decrescendo on the overtone while keeping pitch steady to train consistent support.
Step 4: Experiment with voicing and fingerings. Slightly raising the back of the tongue (“ee”) helps higher partials. If a particular overtone refuses to speak, try adding or releasing a right-hand finger to see if a tiny vent change stabilizes it. Once you find a stable response, gradually return to the original fingering.
If squeaks persist, slow everything down. Use very soft attacks, almost like a breath start, and avoid tongue pressure spikes. Some players benefit from practicing overtones on a neck and mouthpiece alone first, then adding the full clarinet once voicing control improves.
Practice Plan, Measurable Goals and Expected Player Outcomes
A clear practice plan turns overtone work into predictable progress. Divide your overtone time into discovery, stabilization and integration. Discovery is where you first find new partials. Stabilization is where you hold them steadily. Integration is where you connect them to normal fingerings and repertoire.
For most intermediate and advanced players, 5 to 10 minutes of overtone practice per day is enough to see benefits without fatigue. On busy days, even 3 focused minutes on low E and low F can maintain progress. Use a timer so the work stays intentional and does not expand to the point of embouchure strain.
Short-term goals might include: producing the 3rd partial on low E and matching it to a normal B, eliminating squeaks on overtone attempts for one full week, or expanding your range to include the 5th partial on at least one fundamental. Write these goals down and review them weekly.
Expected outcomes from consistent overtone practice include a more resonant tone in all registers, smoother transitions between chalumeau and clarion, better throat-tone intonation and more secure altissimo entries. Many players also notice that soft attacks become easier and that their sound carries better in ensemble settings.
Teachers can assess progress by listening for increased ring in the sound, more stable pitch on sustained notes and fewer embouchure adjustments during register shifts. Students should record themselves weekly on a simple scale and a short excerpt to hear how overtone work is changing their everyday playing.

FAQ
What is clarinet overtone?
A clarinet overtone is a higher harmonic pitch that sounds above a fundamental note without changing the written fingering. These overtones follow an odd-harmonic pattern because of the clarinet's closed cylindrical bore and are important for rich tone, accurate intonation and advanced control across all registers.
How do I produce overtones on clarinet?
To produce overtones, start on a stable low note like E or Bb. Play a steady long tone, then gradually increase air speed and raise the back of your tongue as if saying “ee” while keeping embouchure steady. The sound should jump to a higher pitch, such as B from low E, without changing your fingers.
Which fingerings help produce overtones?
The best fingerings for overtone practice are low E, F, D and Bb in the chalumeau register because they use long, stable air columns. Keep the standard fingering for each note and use voicing and air changes to reach higher partials like B, C, A and F. Overtone charts can show which partials are realistic for each fundamental.
Why are my overtones squeaky or unstable?
Squeaky or unstable overtones usually come from a combination of reed setup, embouchure tension and inconsistent air support. Check that your reed is balanced and not too soft or hard, relax the jaw while keeping firm corners, and focus on fast, steady air. If problems persist, return to squeak-free long tones before more overtone work.
How often should I practice overtone exercises and what progress should I expect?
Practice overtone exercises 5 to 10 minutes per day, after a proper warm up. Within 2 to 4 weeks, you can expect more reliable 3rd partials on low E and F, fewer squeaks, richer tone and smoother register transitions. Track your success rate and duration of held overtones to measure progress objectively.
