I made this PDF as a practice guide for jazz scales improvisation. For all 12 keys, it has the major and minor scales, Mixolydian and Dorian modes, and the bebop, pentatonic minor, and blues scales. All the scales are purposely written in C with accidentals so the player can focus on the notes and muscle memory instead of the key signature. If it's not too much trouble, could a few people look through it and make sure I haven't made any glaring errors? I proofread a couple times, but "measure twice, cut once" and all that. It's good to have other people check it.
