Field notes
The reference spans 180 chords, 144 scales and modes, all 24 major and minor keys, and 14 common progressions. Its listed extras include a tap-tempo metronome, microphone or reference-tone tuners, a chord finder, a transposer and a progression builder that shares loops as links. The homepage says the sound is synthesized note by note; these are site descriptions, not independently verified test results.
