Alternate 
Fingering Chart for Boehm-System Alto, Bass, and Contrabass Clarinet
Chalumeau 
Register: E3 to B 4

This 
fingering chart includes both basic fingerings and alternatives that are more 
appropriate in some passages. Some alternate fingerings are designed for fast 
passages, while others modify the tone, color, or pitch at normal and extreme 
dynamic levels. These fingerings apply to Boehm-system alto, bass, and contrabass 
clarinet unless specified otherwise. There is a separate alternate 
fingering chart for soprano clarinets, which includes many alternates that 
also apply to alto, bass, and contrabass clarinet. The throat 
tone (F#4 to Bb4) and clarion (B4 to C6) fingerings 
are identical among soprano, alto, bass, and contrabass models and are covered 
on the soprano fingering chart.
