Piano Scales and Modes

All 151 scales: 12 scale types on every one of the 12 roots, plus 7 scales people know by their other spelling. Each has its notes, step pattern, degrees and chords.

A scale tells you which notes sound at home together; the chords built from it follow automatically. Learning a scale type is far quicker than memorising chords one at a time, because the same step pattern transposes to all twelve keys. Practise any of them with note highlighting in the app.
