Music Makers

Chiptune tracker with a whole song's worth of channels, shareable as a URL that contains the entire tune inside it.

Drag four blobs up and down and they sing genuine four-part harmony, trained on real opera singers, always in key.

The cat plays whatever key you press, on bongos, a keyboard or a full drum kit. Peak internet, and still maintained.

Fourteen small experiments — spectrogram, harmonics, arpeggios — that explain how music works by letting you break it.

Dress beatboxers in different outfits and each one adds a loop, building a full a cappella track by drag and drop.

Faithful browser rebuild of the Roland TR-808, down to the orange buttons and the cowbell nobody can leave alone.

Ableton's free course on beats, basslines and song structure, taught by handing you the instruments inside the page.

Multi-instrument piano roll in a browser, backed by thousands of user sequences you can open, pull apart and ruin.

Every letter on the keyboard fires a sound and a matching shape, and mashing the whole row is the correct way to use it.

One piano, several people, one link — everybody's keys light up in a different colour and it descends into noise fast.

Grid sequencer with a marimba and a drum kit, tuned so that anything you tap sounds passable, then shared as a link.

Tap any key in rhythm and it plays the next chunk of Clair de Lune, so timing is the only skill actually required.

Same idea as typing but with notes rather than drums — write a paragraph, receive a surprisingly pretty melody.

Type words and each letter becomes a drum hit, so your own name comes out as a loop you will struggle to stop playing.
