553 chords across 12 roots. Each one opens on its common shapes, with the shell, drop 2, drop 3, rootless and open-string voicings derived for it.
The shapes most songs are actually built from.
What each kind of chord is for, and every chord of that kind on every root.
Chord shapes with no open strings in them, which slide: one shape, twelve chords.
Looking for the chords of a key rather than a root? The key explorer groups them by what they do, and the neo-soul harmoniser puts chords under a melody. The same chords with no key attached — one shape and twelve roots — are on the moveable shapes page, and read as scales rather than as shapes they are on the scale index. Where the shapes and the theory come from is on the about page.
Shows each chord the way this style would voice it, and marks which of its alternatives belong to the idiom.
