Alternate 
Fingering Chart for Heckel-System Bassoon
First 
Octave: B
1 to F3
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. The fingerings apply to Heckel-system (German) bassoons. There 
is a separate alternate fingering chart for Heckel-system 
contrabassoon.
The 
fingering scheme explains the text and keys used 
to depict fingerings.
