Example # 1 : C Major Scale - Do the same fingering on the descent.
Example # 2 : A minor 7th Scale - Do the same fingering on the descent.
Suggestion : Use your own fingering style if this does not fit you and also
manage to create your own comfortable fingering on the other scales. (Works best with using the
most comfortable finger you use on the next closest note your hand allows you to reach.)
Some particular difficult instrumental parts require strict finger position discipline.
