Understanding the layout of a clarinet fingering chart is the first step toward technical proficiency. The modern Boehm system, which features 17 keys and 6 rings, offers a logical but sometimes complex series of combinations. Mastery of these fingerings determines not just the notes played, but the fluid connection between registers and the overall intonation of the instrument.

Understanding the Anatomy of a Clarinet Fingering Chart

Most clarinet fingering charts utilize a standardized visual representation of the instrument. To use these charts effectively, one must recognize the symbols for the left and right hands.

The top section of a diagram usually represents the left hand. The thumb hole on the back is labeled 'T', and the register key just above it is 'R'. The three main holes on the front for the left hand are numbered 1, 2, and 3. Beside these are side keys: the G# key, the A key, and the various trill keys.

The bottom section represents the right hand, with holes 4, 5, and 6. Below these are the pinky keys used for the lowest notes of the instrument and their corresponding clarion counterparts. When a circle is filled, the hole is covered; when it is empty, the hole remains open. Lines or specific shapes outside the main vertical line represent the auxiliary keys, such as the E-flat/B-flat side key or the 'fork' Eb fingering.

The Chalumeau Register: E3 to Bb4

The lowest register of the clarinet, the Chalumeau, is known for its rich, dark timbre. Fingering these notes involves a cumulative process of adding fingers.

Starting at the bottom, low E (E3) requires all six main holes to be covered, plus the left-hand thumb hole and the specific pinky keys (usually the bottom-most keys on both the left and right stacks). As you move up to F, F#, and G, you gradually lift the pinky keys and then the fingers of the right hand.

  • Low G (G3): This is often the first note beginners learn. It requires the thumb and the first three fingers of the left hand.
  • The Throat Tones: As you reach G4, G#4, A4, and Bb4, the fingerings become 'shorter.' These notes use keys located at the top of the upper joint. The G#4 is played with the first finger on the side key, A4 adds the top front key, and Bb4 is produced by adding the register key to the A4 fingering.

Because throat tones involve a very short vibrating column of air, they can often sound 'thin' or 'fuzzy.' A common professional recommendation is to use 'resonance fingerings'—keeping some right-hand fingers down while playing G# or A to add depth to the sound and stabilize the pitch.

Crossing the Break: The Transition from Bb4 to B4

The 'break' is the most challenging technical hurdle for clarinetists. It occurs when moving from the throat tone Bb4 (a short-tube note) to B4 (a long-tube note using almost all fingers). This jump requires the addition of the register key and a complete change in hand position.

To master this transition on your fingering chart, focus on the 'preparatory' fingering. For a smooth B4, the fingers of the right hand should ideally already be in place or 'hovering' close to the holes while playing the preceding Bb. This minimizes the physical movement required at the exact moment of the register shift.

The Clarion Register: B4 to C6

By pressing the register key (R), the clarinet skips a perfect twelfth. This means the fingering for low E3, when the register key is added, produces B4. This consistency makes the Clarion register relatively easy to memorize if the Chalumeau fingerings are already secure.

  • C5 to G5: These notes follow the same sequence as F3 to C4, but with the register key depressed.
  • High A5 and B5: These utilize the top fingers of the left hand.

In the Clarion register, intonation becomes a primary concern. Depending on the specific make of the clarinet (such as R13 or Selmer models), certain notes like high C6 might run sharp. Many players adjust the fingering by slightly opening or closing specific lower keys to find the center of the pitch.

The Altissimo Register: C#6 and Beyond

The Altissimo register is where the clarinet fingering chart becomes most varied. These notes are produced by manipulating overtones, meaning there are often multiple fingerings for a single note, each with different benefits for intonation or ease of connection.

  • High D6: A standard fingering involves the register key, the thumb, the 2nd and 3rd holes of the left hand, and the 4th, 5th, and 6th holes of the right hand, often leaving the first hole (index finger) open to act as a vent.
  • High G6: This note often requires the use of the 'preceding' fingerings plus specific side keys to encourage the air to vibrate at a higher partial.

When exploring Altissimo fingerings, air support and voicing (the position of the tongue) are as important as the finger combination. A fingering that works perfectly for one player might sound flat for another due to differences in mouthpiece setup and embouchure.

Chromatic and Alternate Fingerings

A comprehensive fingering chart is incomplete without alternate (or 'enharmonic') fingerings. These are essential for playing fast passages where standard fingerings would cause 'finger twisting.'

The Pinky Key Rules

Most professional clarinets have redundant keys for E, F, F#, and G in the low register (and B, C, C#, D in the Clarion). The general rule is to alternate hands. If you play a low F with your left pinky, the next note (like E or G) should ideally be played with the right pinky. This prevents a 'sliding' motion which is noisy and slow.

The Forked Eb/Bb

In the middle of the staff, B-flat (and low E-flat) can be played using the side key or a 'forked' fingering (1st and 3rd fingers of the left hand). The side key is generally preferred for its superior tone and pitch, while the forked version is used in specific chromatic sequences where the side key is physically unreachable.

Trill Fingerings

Trills require specific, non-standard fingerings to allow for rapid oscillation between two notes. These often sacrifice tone quality for speed. For example, a trill from F5 to G5 might use a side key rather than the standard G5 fingering to minimize the distance the fingers must travel.

Technical Tips for Fluid Fingering

Simply knowing where to put your fingers is only half the battle. The physical execution determines the quality of the transition.

  1. Hand Position: Keep fingers curved, as if holding a tennis ball. This allows the pads of the fingers to cover the holes securely with minimal pressure.
  2. Finger Height: Fingers should stay within a centimeter of the holes. Excessive lifting slows down technique and creates 'thumping' sounds.
  3. The Right Thumb: The thumb rest should sit between the nail and the first joint of the right thumb. This supports the weight of the instrument and allows the other fingers to move freely.
  4. Pinky Independence: Practice moving the left and right pinkies independently without tensing the rest of the hand. Tension in the palm is the leading cause of missed notes in the low register.

Ergonomics and Instrument Care

If certain fingerings on your chart aren't speaking correctly, it might not be your technique. The clarinet is a precision instrument where a leak of even a fraction of a millimeter can prevent a note from sounding.

  • Pad Sealing: Periodically check that your pads are sealing. If low E is difficult to play even with firm pressure, a pad in the upper joint might be leaking.
  • Bridge Key Alignment: When assembling the clarinet, ensure the bridge key (the piece connecting the upper and lower joints) is perfectly aligned. If it is misaligned, the rings on the bottom joint will not close the pads on the top joint, making the middle-register notes impossible to play.

Conclusion: Building Muscle Memory

The ultimate goal of studying a clarinet fingering chart is to move beyond it. Through scales, arpeggios, and slow technical exercises, these combinations become part of your muscle memory. Start by mastering the Chalumeau register, then gradually work through the Clarion and Altissimo ranges.

When encountered with a difficult passage in your repertoire, refer back to the chart to see if an alternate fingering exists. Often, the 'hard' way is only hard because the most efficient fingering hasn't been discovered yet. Consistent practice with a focus on hand relaxation and precise finger placement will eventually make the most complex charts feel like second nature.
