About C♯5 on the clarinet
The clarion is the clarinet’s bright, singing register. Almost every clarion fingering is a low-register fingering plus the register key — which is why the low register is worth learning properly first.
C♯5 is note 22 of the 42 in the full clarinet fingering chart, sitting between C5 below it and D5 above it. Like every fingering on this site, it was checked against Yamaha’s official chart and the Woodwind Fingering Guide before publishing.
Practising C♯5
If this note squeaks or drops to its low partner, check your left thumb: it must keep the thumb hole covered while its tip presses the register key. Half-covering the hole is the usual culprit.
