About this app

JamBrew turns your phone into an instrument you can actually jam on — even if you've never played a note.

The keys aren't fixed notes. They're steps along a scale: tap to go up, tap to go down. Whatever you play stays in key, so there's no wrong note to hit. Press and slide to bend a note like a real string.

Pick a world and start playing:
• Bright — major/minor pentatonic, morning and sunshine
• Koto — Japanese pentatonic, a rock garden in the rain
• Blues — blues scale, real bends, a 12-bar band behind you
• East — phrygian dominant & Hungarian scales, desert and trance
• Dream, Gamelan, Synthwave, and more

Every style comes with a live backing band — sampled drums, bass and arpeggio — so you're jamming with something from the very first tap. Swap the lead for any of 100+ real instruments: harp, sitar, harmonica, sax, koto, flute and beyond.

Tilt for vibrato. Record a clip to share. No ads, no accounts, no wrong notes.

A jam instrument in your pocket.
