The 7 hole flutes have an added thumb hole on the under side of the flute for the upper hand. This thumb hole allows for the above octave notes to be tuned and played more accurately. This design was developed by Steve Petermann.
The standard pentatonic minor notes and cross finger notes are tuned and fingered the same as the concert flute. The difference is the fingering for the above octave notes which involves opening the thumb hole and using a different fingering pattern.
The chart below uses the key of G4 as an example of all the fingerings for the 7 hole flute.
