Understanding the clarinet fingering chart involves more than just memorizing a map of holes and keys. It requires a grasp of how air moves through the Boehm system and how different registers utilize the same fingerings to produce notes an octave and a fifth apart. The clarinet is a unique instrument in the woodwind family because it overblows at a twelfth rather than an octave. This means the fingerings used for the lowest notes are repeated with the addition of a register key to produce the middle register. Navigating this complexity is the foundation of becoming a proficient player.

The Fundamental Logic of the Boehm System

Modern clarinets primarily use the Boehm system, which was adapted from flute mechanics in the 19th century. This system utilizes a series of rings and levers that allow a human hand with only ten fingers to cover seventeen or more holes and operate multiple keys.

When looking at a standard clarinet fingering chart, the visual representation usually consists of two main stacks. The upper stack is operated by the left hand (thumb on the back, three fingers on the front), and the lower stack is operated by the right hand (three fingers on the front). Side keys and pinky keys extend the range and provide alternate paths for chromatic passages. The efficiency of your technique depends on keeping the fingers curved and close to the holes, a concept known as "economy of motion."

The Chalumeau Register: E3 to Bb4

The lowest register of the clarinet, known as the Chalumeau register, is characterized by a rich, dark, and woody timbre. The lowest note on a standard Bb clarinet is E3. To play this note, every single hole must be covered, and both pinky keys for E/B must be engaged.

The Low E, F, and G Sequence

  • Low E3: Left hand thumb, 1, 2, 3; Right hand 4, 5, 6; and the right-hand pinky key for E/B.
  • Low F3: The same as E3, but the right-hand pinky shifts to the F/C key.
  • Low G3: Lift the pinky and the third finger of the right hand. Only the thumb, 1, 2, 3, 4, and 5 remain down.

This register is excellent for developing air support because it requires the most air volume to vibrate the entire length of the instrument. New players often find that if the low E or F does not speak, it is almost always due to a tiny air leak in one of the upper holes or an improperly seated pinky key. It is recommended to check the seal of the rings periodically. If the skin of the finger does not create a perfect vacuum over the tone hole, the note will squeak or fail to sound.

The Throat Tones and the Problem of Resonance

As you move up the scale into the "Throat Tones" (G4 to Bb4), the amount of vibrating tubing decreases significantly. These notes use the keys located near the top of the clarinet, close to the mouthpiece. Because the air exits the instrument so high up, these notes can often sound thin or "stuffy."

  • G#4: Operated by the first finger of the left hand on the small key above the first hole.
  • A4: Operated by the left-hand index finger pressing the A key.
  • Bb4: This is often the most problematic note. It is played by pressing both the A key and the register key with the left-hand thumb simultaneously.

Technique enthusiasts often use "resonance fingerings" for these throat tones. By putting down some of the fingers of the right hand while playing G# or A, the player can change the internal tuning and add a bit of warmth to the sound. For example, when playing an A4, keeping the holes 4, 5, and 6 covered can sometimes improve the transition to the next register, though this varies depending on the specific bore of the instrument.

Crossing The Break: The Greatest Technical Hurdle

"The Break" refers to the transition between the throat tone Bb4 and the clarion register B4. This move is difficult because it requires going from pressing almost no keys to covering every single hole plus the register key in one smooth motion. It is the moment where many beginners feel frustrated, as the slightest misalignment of a finger results in a squeak.

To master this transition on the clarinet fingering chart, focus on the "Preparation Method." If a passage moves from a throat tone to a clarion note, the right-hand fingers (4, 5, and 6) can often remain down during the throat tone. This keeps the hand in place and ready to seal the holes the moment the thumb hits the register key for the B4.

The Clarion Register: B4 to C6

Once the register key is engaged, the clarinet enters the Clarion register. Because the clarinet overblows a twelfth, the fingering for B4 is exactly the same as the fingering for E3, plus the register key. This symmetry continues all the way up:

  • B4: Same as E3 + Register Key.
  • C5: Same as F3 + Register Key.
  • D5: Same as G3 + Register Key.
  • G5: Same as C4 + Register Key.

This register is where the clarinet is most famous for its lyrical, singing quality. The intonation here is generally more stable than in the Chalumeau register, but the higher notes (around A5 and B5) can sometimes run sharp. Adjusting the voicing—the position of the tongue and the speed of the air—is just as important as the fingering itself.

The Altissimo Register: C#6 and Beyond

The Altissimo register starts at C#6. These notes are produced by venting specific holes to encourage the air column to vibrate in even higher partials. These fingerings are significantly more complex and often have multiple variations depending on whether the player needs better intonation, a softer dynamic, or a faster technical connection.

  • High D6: Often played with the register key, the thumb hole (sometimes vented), and the 2nd and 3rd holes of the left hand, plus the 4th hole and the G# key in the right hand.
  • High E6: A common fingering involves the register key, left hand 1 and 2, and right hand 4 and 5, with the C#/G# pinky key.

Altissimo fingerings can feel inconsistent between different brands of clarinets. A fingering that is perfectly in tune on a R13 might be flat on a Selmer or a Yamaha. It is beneficial to keep a personal notebook of which altissimo fingerings respond best to your specific setup (mouthpiece, reed strength, and instrument).

The Logic of Alternate Pinky Keys

One of the most confusing aspects of a clarinet fingering chart for intermediates is the redundancy of the pinky keys. There are four keys for the right pinky and four for the left (on most modern professional models). These keys control the low E, F, F#, and G# (and their Clarion equivalents B, C, C#, and D#).

The rule of thumb is: Never use the same pinky twice in a row if you can avoid it.

If you are playing a passage that goes from Low F to Low E, you should play the F with your left pinky and the E with your right pinky. If you try to slide your right pinky from the F key to the E key, there will be a "blip" or a gap in the sound. Learning to alternate these keys is essential for chromatic scales and complex technical etudes.

Common Alternate Fingerings

  1. The Long Bb: Instead of using the throat A and register key, you can play a Bb4 by fingering an A4 and using the side trill key (the third one down from the top). This is often used for fast chromatic runs or trills from A to Bb.
  2. Forked Eb/Bb: In the middle of the stacks, there are fingerings for Eb4/Bb5 that use a "forked" position (1 and 3 of the left hand). This is useful in certain key signatures like Eb major, though the tone quality is often slightly stuffy compared to the side-key fingering.
  3. Side Eb/Bb: Using the thumb, 1, 2, and the middle side key on the right hand. This is the preferred fingering for resonance and clarity when the tempo allows for it.

Chromatic Fingerings and Trills

Chromatic passages require a different mindset than diatonic ones. The clarinet fingering chart usually provides several options for sharps and flats. For example, F# can be played using the bottom right pinky key or by using the first finger of the right hand (the "side" F#).

Trills require fingerings that prioritize speed over perfect intonation. A trill from G5 to A5 using standard fingerings would be clunky. Instead, there are specific trill keys (the four keys operated by the side of the right-hand index finger) that allow for rapid oscillation. While these keys often make the note slightly out of tune, the speed of the trill masks the intonation issues, providing a shimmering effect that is central to classical and romantic repertoire.

Ergonomics and Hand Position

A fingering chart tells you which keys to press, but it doesn't always tell you how to press them. Proper ergonomics are vital to prevent long-term strain and to ensure that fingerings respond instantly.

  • The "C" Shape: The hands should maintain a relaxed "C" shape, as if holding a tennis ball. This allows the pads of the fingers to land squarely in the center of the tone holes.
  • The Thumb Angle: The right thumb should support the clarinet at the first joint. If the thumb is too far under the rest, it restricts the movement of the other four fingers.
  • The Left Thumb: The left thumb must be angled so it can easily cover the hole and press the register key with a slight upward rocking motion of the wrist, rather than a jump of the finger.

Intonation Adjustments Through Fingering

No clarinet is perfectly in tune across all registers. As a player, you must use the fingering chart as a starting point and adjust based on what you hear.

  • Sharpness in the Highs: If the high C6 is sharp, adding the low F/C pinky key can sometimes pull the pitch down.
  • Flatness in the Lows: If the low E3 is flat, opening the G# key slightly (if possible without losing the seal) can sometimes help, though this is a very advanced and rare adjustment.
  • The Bell Note: Low E and F are often the most out of tune because they use the full length of the instrument. Pulling out at the bell can help these specific notes without affecting the rest of the instrument as much as pulling at the barrel would.

Maintenance Affects Fingering Accuracy

If you find that certain fingerings on the chart are not working, it may not be your technique. The clarinet is a mechanical machine. Over time, the corks under the keys compress, and the pads can dry out or tear.

  • Key Height: If a key doesn't open far enough, the note will be flat and stuffy. If it opens too far, the note will be sharp and thin.
  • Spring Tension: If the springs are too light, the keys might not seal under the pressure of your air. If they are too heavy, your fingers will tire quickly, leading to sluggish technique.
  • Pivot Screws: If these are loose, the keys will "wiggle," making it impossible to get a clean seal on the holes.

Summary of Finger Placement for Success

To effectively use a clarinet fingering chart, one should memorize the notes in clusters. Start with the Chalumeau notes, then learn the Clarion equivalents. Once the relationship of the twelfth is understood, the chart becomes half as daunting.

Focus on the following priorities:

  1. Sealing the Holes: This is 90% of the battle for beginners.
  2. Coordinating the Register Key: Essential for "crossing the break."
  3. Left/Right Alternation: Essential for smooth chromaticism.
  4. Voicing and Air Speed: The secret to making the altissimo register speak.

As the date progresses into the mid-2020s, new innovations in clarinet design continue to appear, such as auxiliary low Eb keys on Bb clarinets or improved venting for throat tones. However, the core fingering chart remains the same as it has for over a century. Mastery comes from slow, deliberate practice of scales and chromatic runs, ensuring that every finger lands precisely and simultaneously. Whether playing a Mozart concerto or a jazz solo, the fingering chart is the map that allows the musician to navigate the instrument's complex topography.
