Making music is as easy as 1-2-3…
Click or tap the Make Chord or Make Scale button on the center console.
Click or tap to select one or more notes, from 0 through 11, on the circle.
Click or tap the Enter button to see and hear the interval, chord, or scale you’ve created.
Tip: When making chords, limit the number of notes you select from 2 to 4, or for chords with tensions, 5 or more. When making scales, select from 5 to 7 notes, or more for longer scales. And always try to enclose the center of the Harmonagon within the shapes you create. When shapes do not encompass or at least intersect with the Harmonagon center point, the chord or scale produced will in most cases return “undefined.”
