C4 Bassoon Fingering
How to play C4 on the bassoon: Flick the B key as the note starts · 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 C4 fingering, step by step
- Flick the B key with your left thumb as the note starts: touch it for the attack, then let it go while the note keeps sounding. The flick vents the note so it starts cleanly instead of cracking — it is never held down for this note.
- 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: flick the B key as the note starts · left hand 1-2-3.
About C4 on the bassoon
The second octave is where the bassoon’s special techniques arrive together. It opens with the three partial-hole notes, where the left index finger covers a quarter, a half and three quarters of its hole; continues through the flick notes, where a thumb key is tapped at the attack and released; and closes with plainer fingerings in which the whisper key quietly retires and the thumb keys take over the work.
C4 — middle C — is the last of the flick notes: the B flick key starts it, and then the plain fingering (both hands’ top fingers, right hand open) sustains it. Above C4 the flick keys retire from the basic fingerings until they return, in a different job, at the very top of the chart.
C4 is note 27 of the 37 in the full bassoon fingering chart, sitting between B3 below it and C♯4 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 C4
Practise the flick as a separate tap: finger A3 silently, tap the A flick key with the thumb, then play the note and flick at the same instant — the thumb should already be hovering over the cluster. For the partial-hole notes, work against a tuner and learn the fractions by feel; your finger cannot watch itself in a fast passage.
