GenChord - Guitar Scale Chord

GenChord Guitar is a chord and music theory tool built around the guitar fretboard. It does more than show where to place your fingers. It connects chords, scales, fingering shapes, diatonic harmony, and tensions on the same fretboard, so you can understand why each voicing works.

Use the Library to search chords by root, type, and tension, including triads, seventh chords, sixth chords, sus, aug, dim, half-dim, b5, #5, bb7, and 9/11/13 tensions. Open Chord Explain to see the same chord across the Mi, Sol, La, Si, and Re shapes, which correspond to the CAGED system.

Generate I-VII diatonic chords from major, minor, harmonic minor, melodic minor, and church modes. Start from any string and fret in the Fingering Tool to build a scale shape and the chords inside it. Play voicings as strums, arpeggios, or randomized notes, then save useful chords into Collections with iCloud Drive or local storage.

GenChord Guitar is a fretboard-first way to study harmony, guitar voicings, accompaniment, arranging, and improvisation.
