About C♯6 on the clarinet
The altissimo register sits above the clarion. Its fingerings no longer copy the low register; each note has its own combination, often with a pinky key added to tune it, and advanced players choose between variants by instrument and by passage.
C♯6 is the first altissimo note. Altissimo fingerings are built note by note rather than copied from the low register, and most of them have several accepted variants.
C♯6 is note 34 of the 42 in the full clarinet fingering chart, sitting between C6 below it and D6 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♯6
Altissimo notes need fast, focused air and a firm — not biting — embouchure. Learn this note by approaching it from the clarion note below, a few times a day, rather than in one long session.
