Guides

How do I learn a song part by part?

Choose the song above. AI splits it into six stems. Solo the instrument you are learning, press Loop from here at the start of the hard bar and to here at its end, then pick a slower speed.

Slow it down without changing the key

Speeds from 50% to 90% keep the original key, so you can play along in tune while you learn. Go back to 100% once it feels easy.

See the chords as it plays

The current chord and the next one show under the mixer, worked out from the harmony instruments, so you can follow along on guitar or piano.
