LOVE THIS PROGRESSION?
Turn it into a full song: your progression becomes the verse and chorus, with a generated intro, pre-chorus lift, bridge and outro around it — as an unsaved draft in the Songs tab.
Progressions are built from the mode's own chords and weighted toward moves
real songs use — dominants resolving home, no chord repeating back-to-back —
so each roll lands somewhere musical. Roman numerals show each chord's place
in the scale; the small notes under a chord are its three chord tones.
Tap any chord to hear it — hold it to see its guitar & piano fingerings. Saved progressions and songs live on this device — and mirror to your other devices if you turn on Personal Sync in the Saved tab.
Nothing saved yet. Roll a progression you like on the Progressions tab and hit Save progression.
No saved songs yet. Build one in the Songs tab and press 💾 Save song.

☁️ PERSONAL SYNC
Your saved progressions & songs can mirror between your own devices — phone ⇄ computer — behind a passcode. It's optional and personal: the app works fully without it, for anyone. Only your saved library syncs; a song draft you're still editing stays on this device until you press 💾 Save song.
Sync is off on this device.
CREATE A SONG
Generate full song composes a whole arrangement in that key & mode — intro, verse, pre-chorus, chorus, bridge, outro — with the verse and chorus repeating like a real song.
Your saved songs live under Saved → 🎵 Songs — open one there to bring it into the editor.
SONG BUILDER
Saved progressions are added by their scale degrees, so they transpose into this song's key & mode automatically.
Full-song templates built on music-theory standards, shown in this song's key & mode. Applying one replaces the song's current sections.
