Explore voicings across instruments and tunings.
Chord maps show you the voicings available for any root note and chord type on your instrument. Think of them as a chord dictionary that adapts to the instrument and tuning you actually play.
On the web, chord maps work without an account. Open them at /chords.
The instrument switcher lives in the top bar on every page. It shows the current instrument and tuning, for example "Guitar · Standard". Open it to switch.

A tuning legend above the grid shows the open-string notes for the current tuning.
The map loads the first 50 shapes. Choose Show More Shapes to load 50 more, up to a maximum of 240. Some chords have many playable shapes on your instrument and others only a few.
Shapes are ranked by how complete and playable they are. Shapes that contain every chord tone, include the root, use more strings, and sit closer to the nut rank higher. Lower positions tend to come first, but a complete barre chord can outrank an incomplete open shape.
Each diagram shows where to fret each string, which strings are open, and which are muted. Below it you will see the notes the shape contains.
