A Musical Handshake: Change One Note, Keep Two Voices

Try a tiny music-making exchange: one person hums or taps a three-beat phrase; the other answers by changing just one thing—a note, the rhythm, or even where a pause falls.

Then let the first person choose what happens next: keep the change, offer another, or leave the phrase unfinished. The small boundary makes room for a reply without turning one person’s idea into someone else’s replacement. No instrument or polished tune required—just two distinct contributions, with credit intact.
