How to read the pictures
Holes and keys marked in red are closed or pressed. Each picture shows the Boehm system and the German system. For the upper register, from B4 upward, you also press the register key with your left thumb.
E3 – B3 8 notes
40 notes for clarinet, from E3 to G6, each with a picture of its fingering. Notes with two names, like A# and Bb, share one picture. Notes are written pitch, as in your sheet music.
