I always had trouble reading scales. I could never line up the fingering with the notes. The finger numbers were too small and seemed to keep moving from note to note. Fortunately, it didn’t matter because I played scales by ear and memorized the fingering easily.
When a few a my students had the same problem reading the scales, I got the idea for my first picture scale. This is the 2 octave harmonic minor version. While I’ve received some criticism for not insisting students read the scales, I don’t let it bother me because we all have different students with different needs. If you have a student who is helped by this, I would love to know.
