About A3 on the bass clarinet
The chalumeau is the bass clarinet’s glory — the dark, woody low register the instrument exists for. These fingerings are the foundation of everything above them: add the register key to most of them and the same fingers produce the clarion register a twelfth higher. The register starts one note lower than the soprano’s, on the low E♭ extension key.
In this part of the low register the left hand stays completely down while the right-hand fingers lift away one at a time: A3 keeps right-hand fingers 1 and 2 down, B♭3 keeps only finger 1, and C4 lifts the whole right hand.
A3 is note 7 of the 34 in the full bass clarinet fingering chart, sitting between G♯3 below it and B♭3 above it.
Doubling from soprano clarinet? This is the same fingering as A3 on the clarinet — the Boehm fingerings are shared across the clarinet family, which is why the bass is the standard first double. Like every fingering on this site, it was checked against the Woodwind Fingering Guide's bass clarinet charts and Yamaha's official chart before publishing.
Practising A3
Low bass notes speak best with a great deal of slow, warm air. If this note cracks, gurgles or will not start, check first that the pinky keys are sealing their pads completely — the levers are long, and a half-pressed pinky key is the usual culprit down here.
