Doubling from soprano clarinet? This is the same fingering as C♯4 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 C♯4
Keep the left hand down and lift only the fingers this fingering asks for. Extra lifted fingers make the pitch wander and the tone thin out — more noticeable on the bass than on the soprano.
