Why 120 chords?

Open the inversion explorer from any card to hear all three or four voicings, or use the chord finder to identify a selected set of notes. These are twelve pitch-class roots multiplied by ten common formulas. Enharmonic spelling can depend on harmonic context; the displayed note names follow diatonic chord construction. Not every theoretical spelling has a separate page. This library links to 29 authored lessons; where an enharmonic root is used (for example, D♭ minor versus C♯ minor), the link is explicitly labelled and the note spelling may differ. Additional individual lessons are not automatically generated.
