[Find 370+ chords instantly]
12 roots x 31 types fully covered — major, minor, 7th, M7, m7, 6, sus4, add9, dim, aug, and tensions like 7(9), 7(b9), 7(#9), 7(13), M7(13), m7(11) and more. Just pick a root and a type to see the fingering at once. Each chord includes multiple voicings, so you can explore other shapes up the neck.
[Tap to hear it]
Built-in realistic guitar samples play every time you select a chord, so you learn by ear. Compare how each voicing sounds.
