How it works
Formula
New root = old root + semitones (slash bass moves too)Capo fret = (target key − shape key) mod 12Worked example
Given: C – G – Am – F up 2 semitones; sound in E using C shapes
- C→D, G→A, Am→Bm, F→G.
- E − C = 4 semitones: capo on fret 4.
Result: D – A – Bm – G; capo 4 with C shapes sounds in E.
Limitations
- Only common chord spellings are recognized; chords mixed into lyric lines need square brackets.
How to use
- 1Paste your chart with chords on their own line above the lyrics, or inline like [Am].
- 2Shift with + / − or pick the target key.
- 3Copy the result. For a capo, choose the key you want and the shapes you'd like to play.
FAQ
How do I work out the capo fret?
Each fret raises the pitch a semitone, so capo fret = target key − shape key. To sound in E using C shapes, C to E is 4 semitones: capo on fret 4.
Why sharps in some keys and flats in others?
Auto mode follows the target key's convention: F, Bb, Eb, Ab and Db use flats; G, D, A, E and B use sharps. You can force either.
Will my lyrics change?
No. Only lines made entirely of chords, and chords inside square brackets, are transposed.
