People also ask

Is the backing track generator free?

Yes, in your browser with no signup. The Jam plugin adds your DAW's transport, recording and the chart saved with your session.

What chords can I type?

Major, minor, 7ths, maj7, m7, m7b5, dim7, sus, 6, 9, 13, alt and add9 chords, plus slash chords like C/E. Bars go between | lines, % repeats a bar and - holds a chord.

Can I practise jazz standards?

Yes: type the chord changes of any tune into the chart. Chord progressions aren't the melody, so you can write out the changes you're learning and loop the hard parts.

Can I change the tempo and key?

Yes. Switch Tempo to Free to set any BPM, and use Transpose to move the whole band up or down in semitones.
