Help others learn the song
Say yes to featuring a harmony when you share it, and it's public: we may choose your part as the voice everyone learns from, credited to you by your profile name. For singers 18 and over. Untick it any time.
Share what you sing
When every part is in, send it as a link, a short video with the words, or a file. Polished is on unless you turn it off.
Start singing
Free, in your browser. No account needed to start.
A link anyone can play
A share link plays your harmony on any phone or computer. Only people with the link can find it, and its page offers "Learn this harmony" so friends can try it too. Post it to X or Bluesky with the post ready to go.
A video with the words
Share as a video makes a vertical video for TikTok, Reels and Shorts: each part's waveform moving in its colour, with the words lighting up as they're sung, so it works with the sound off.
