๐ŸŽธ Capo Calculator

Actual sounding keyD

Calculate the actual sounding key from the guitar chord shape you're playing and your capo's fret position. Or work the other way โ€” from the key you want to play in and the chord shape you'd rather use, find the capo position you need.

How to use

  1. Choose a calculation mode: "find the sounding key from shape + capo position" or "find the required capo position from shape + target key".
  2. Choose the chord shape (key) you want to play.
  3. Depending on the mode, choose the capo position or the target key.
  4. The result is calculated automatically.

FAQ

What does "chord shape" mean here?

It refers to which open-position chord form (like C or G) you finger while the capo is on. The actual sound is that shape transposed up by the capo's fret position.

Can this tell me when no capo is needed?

Yes โ€” a result of 0 for the required capo position means you can play it open, with no capo.

Does this account for the difference between semitones and whole tones?

Yes โ€” since each capo fret raises the key by exactly one semitone, this is calculated precisely using the 12-tone chromatic scale.
