Melody Maker

Melody Maker is a friendly sixteen-step sequencer with four instrument rows and a mascot on each: Pip the bird sings the lead across eight notes of a pentatonic scale, Bo the whale plays bass, Lulu the octopus plays chords and Tum the bear keeps the rhythm on kick, snare, hat and clap. Tap a cell to place a note, tap a coloured key to change its sound, press play and a bouncing ball runs along the grid while the band bobs on every note. Because the scale never has a wrong note, anything you tap in sounds musical.

Echo is the puzzle half and a gentle brain workout: thirty quick levels in five sets, from a single heartbeat on the kick drum to a full band at 120 bpm. Each one plays a short tune and you rebuild it by ear, and by eye, since every note lights up on its cell as it plays. Listen again whenever you like; after two listens the tune's cells appear as ghosts to guide you. A level clears the moment your loop matches, with stars for fewer listens and less time, and nothing ever fails, so it is a calm way to relax and train your ear. Every note has a visual cue on the beat, so the whole game plays fine with the sound off.

The Free studio is yours: set the tempo and the swing, pick one of four scales and a sound for each row, chain up to eight bars, keep six songs in save slots on your device and swap a short share code with a friend to load the loop in another browser. A Groove Score rates any loop for rhythm variety, melody shape and harmony, and the endless Daily Jam hands everyone the same starting loop each day, seeded by the date, to remix as far as you can push it, with today's high score kept on your device and a fresh remix whenever you want one. Every sound is made in your browser as you play.
