Chordindex

Play a chord. See the name. Chordindex listens to whatever you're playing — a MIDI keyboard, the on-screen piano, or the on-screen fretboard — and names it in under a second: the name a musician would say in rehearsal, plus two to six alternate names when they apply. Triads, sixths, sevenths, adds, extensions, altered chords, slash chords and inversions — all identified live, spelled for whatever key you're playing in. Every chord shows the same way on three instruments at once: grand staff, piano, and guitar fretboard. Play a shape on the fretboard and see it on the piano; play a chord on your MIDI keyboard and watch the staff and fretboard follow along. It's also a reverse dictionary. Look up a chord by name and see its tones, its common aliases, a piano voicing, a guitar diagram, and the staff — no instrument required.
