How it works
Four ways to hear the same harmony.
Start from a familiar I–V–vi–IV progression, a jazz ii–V–I, or build your own. Select any bar to adjust its chord, then press Play progression. Each bar lasts three or four beats, according to the time signature.
Sustained holds each chord; Steady pulse marks the beat; Arpeggio spreads the notes; and Strum gives the chord a quick rolling attack. All four are synthesized directly in your browser using Web Audio—no recorded guitar or piano sample is implied.
Share links hold the exact chords and settings. A saved draft is stored only on this device and never uploaded to Rytune. Browser audio starts on a user click; changes to the tempo, chords and arrangement take effect at the next bar while playback continues.
