Guitar, bass, drums and vocals. Tap the screen, sing, or play a real guitar into the mic. Alone or as a band, one phone each.
Singing or playing into the mic works best with headphones, so the mic does not hear the song.
The band keeps playing without you.
Phones and Bluetooth headphones are a bit late with sound. If notes feel early or late, test it here.
Only needed once, by whoever set up the Spotify app (see Help).
Play one string at a time.
Log in to pick a song here. The phone starts it on your Spotify app or speaker, listens, and makes the notes.
Needs Spotify Premium. Spotify only lets the app's owner and four people they add use it, so ask them to add your Spotify email.
Pick a speaker, laptop or other phone, so this phone's mic can hear it. Spotify has to be open there. On an iPhone, playing on the same phone stops when the mic turns on.
Pick a song and a part. Notes slide down toward the line at the bottom. Hit them as they cross it.
Hit notes in a row to raise your multiplier. Miss and your part goes quiet, and the crowd meter on the left drops. If it runs out you are out of the song.
Boost. Glowing notes fill the blue bar on the right when you hit all of them. Once it is half full, press Boost (or Space) for double points. In a band, boosting also brings back anyone who dropped out.
Band. One person starts a band and sends the code or link. Everyone picks a part on their own phone and the leader starts the song. All phones start together. Same room: tick "Same room" so each phone plays only its own part. Anyone with the code can join, so only share it with friends. Scores come from each phone and are not checked.
Your music. Pick "Your music" at the bottom of the song list and play any song out loud near the phone. It listens for the beat and makes notes from what the song did a bar earlier, so they follow the drums and the chords but not the exact guitar part. Guitar, bass and drums only. With Spotify set up, you can search and start a song from here and the set ends when the song does.
Setting up Spotify (once, by one person with Premium): make an app at developer.spotify.com, add this page's address as a redirect URI, tick Web API, and paste the client ID in Settings. Add each friend's Spotify email under User Management (up to four).
Timing. If notes feel early or late, run the tap test in Settings. For the mic, run the mic test without headphones.
All songs, words and sounds are original and made in the browser. Inspired by the band games where you play along with plastic instruments.
