Chord and fretboard tools
Five theory tools in one place. Name a chord from its notes, see how to play it on guitar or ukulele, map a scale on the neck, explore the circle of fifths and move a chord chart to a new key. Press anything to hear it.

Press the notes you have. The chord name appears below.
Chord shapes
Fretboard
The root is in purple. Press any note to hear it. Choose "Just one note" as the scale to find every place a single note lives.
Circle of fifths
Press a key. Major keys are on the outside and their relative minors inside.
| Degree | Chord | Notes | Hear it |
|---|
Chord chart transposer
Paste a chord chart. Lines made only of chords are moved to the new key. Lyrics, section names and ChordPro style [C] chords are handled too.
Tips
- The chord finder also names inversions. Choose a lowest note and C E G with E at the bottom becomes C/E.
- Chord shapes are worked out from the instrument tuning, so they follow whichever tuning you pick.
- On the circle, keys next to each other share almost every note, which is why they sound good together in a song or a DJ mix.
- Moving a chart up or down by 2 semitones is a quick way to find a key that suits your voice. A capo does the same job on guitar.
- Want the scale notes on a piano? Open the Key and scale helper.
