Chord progression studio. Pick a key, tap chords to hear them, loop the progression, and catch the idea before it slips away.
Major and minor keys with the music theory built in and correct — tap to hear it instantly on your device.
Stack chords into a progression and loop it at any tempo, with an arp/strum feel and a bass line under it.
Flip on 7th chords for a jazzier feel, or start from classic pop, 50s, and ballad progressions.
A one-time $3.99 unlock adds MIDI export, drum grooves, and six more instruments. The songwriting core stays free.
