About this app

Jam Bloom is a beginner music maker that helps you make a real song in minutes, even if you have never played an instrument.

Tap a chord pad and the melody grid lights up with the notes that fit, so everything you play sounds in tune. Add a beat from the instant grooves, let the auto bass follow your chords, then record your own melody on top.
