Bars that keep time
The current bar fills as the song plays. Click ahead to jump, shift-click two bars to loop the tricky part.
- 02
Your key, your capo
Transpose to a key you can sing, set a capo position, and every diagram redraws to the shape you actually play.
- 03
Slow it down, hear it back
Drop to half speed without changing pitch, and play the detected chords over the track to check they fit.
