Chord comparator
Pick two chords from the library to see their fingerings side by side: useful for spotting shared fingers before a chord change, or comparing an open shape to its barre equivalent.
This tool shows two chord diagrams side by side, at the same scale, so you can instantly see what they share and what changes from one fingering to the other. It's for anyone preparing a tricky chord change who wants to see which fingers can stay put, or who wants to compare an open shape to its barre equivalent. What it shows: the two fingerings, not the notes or any harmonic analysis. Everything is computed and served server-side, with no account and no JavaScript.
How to use it
Pick a chord in each list, submit: the two diagrams appear side by side. Visually compare what they share (a finger in exactly the same spot on both) and what differs. On mobile, the two diagrams stack one under the other to stay readable.
Tips and things to watch for
- To work on a transition, first spot the fingers that don't move from one chord to the other: those are the anchor points to keep in place during the change.
- Comparing an open shape (say E) to its barre equivalent (say F) shows concretely that it's the same fingering moved up: the barre isn't a new shape to learn.
- The tool compares fingerings, not sounds: two chords that look very close can sound very different, and the reverse is also true.
- If a chord is missing from the list, it isn't in the site's library yet — the full library, filterable by type, shows more.
