Decent attempt.
The theory portion is incorrect in it’s chordal spellings. It is showing the enharmonic spellings versus the correct theory of notation.Good app
The frequency chart and delay calc works for me. There is still room for this app to grow. In the chord section, have the sound of the chord play when selecting the individual chords. In the Harmonic Mixer section. It would be cool if chord progression analysis was added. Roman numerals, and extensions IE: Maj7 Or Maj13 Overall a decent simple app.
