C3 Bassoon Fingering
How to play C3 on the bassoon: Whisper key · left hand 1-2-3.
Filled keys and holes in the diagram are the ones you press or cover, and a part-filled first hole is partly covered — a quarter, a half or three quarters, exactly as the fingering states. The column down the left is the left thumb’s nine keys: the whisper key at the top, then the C♯ key, the three flick keys and the four low keys; a dashed flick key is touched only as the note starts, then released. Below them sit the left pinky’s E♭ and C♯ keys — drawn as two keys, because on the instrument they are two. The columns on the right are the right thumb’s four keys and the right pinky’s three, and the narrow key between the right hand’s second and third holes is the sliver B♭ key.

The C3 fingering, step by step
- Press the whisper key with your left thumb and keep it down for the whole note. It is the bassoon’s register vent: it helps this register speak cleanly, but unlike a clarinet register key it does not choose the register for you — the fingering does that.
- Cover hole 1 with your left index finger.
- Cover hole 2 with your left middle finger.
- Cover hole 3 with your left ring finger. The third left-hand hole is closed by a ring key rather than a plain hole — your finger presses the ring and the pad seals the hole.
In short: whisper key · left hand 1-2-3.
About C3 on the bassoon
The first octave is the bassoon’s foundation, and it is built from the left thumb upwards. The five lowest notes keep both hands fully down while the thumb’s low keys let go one at a time; the whisper key joins at E2 and stays; and the register tops out at F3, the whisper-key-only note with every finger raised. Almost everything above is one of these shapes with a vent changed — a partial hole, a flick, a pinky key — so this register repays slow, exact learning.
C3 is note 15 of the 37 in the full bassoon fingering chart, sitting between B2 below it and C♯3 above it.
Like every fingering on this site, it was checked against Yamaha’s Musical Instrument Guide bassoon chart, the Woodwind Fingering Guide’s bassoon charts and the First 5 Notes bassoon chart before publishing.
Practising C3
Low bassoon notes need slow, supported air and sealed pads. Practise the B♭1-to-D2 ladder as a thumb exercise: hands still, thumb releasing one low key at a time, listening for each note to speak without a bump. If a note will not start, check the reed and the boot-joint pads before blaming your fingers.
