Build beats with blocks!

BeatBlocks is a fun music-making app for iPhone and iPad that lets you build music in the real world using LEGO and other construction bricks.

How does it work?

BeatBlocks uses the camera on your iPhone or iPad with advanced AI to detect Lego bricks of different type and colour. To build a beat, just lay out a pattern of bricks in front of the camera.

Brick detection using AI

Bricks = Beats

The app uses a repeating 8-beat loop to build beats. Each loop plays from left to right, and when the app sees a brick, it plays a sound: so as you build, you make music.

Experiment with patterns and bricks


The app is a creative sandbox for play and discovery, making it super easy to explore beats, bass-lines and melodies just by playing with real-life lego bricks. To change your loop, just move or scatter the blocks around, try out different colours, and wait for the loop to update.

Colours = Sounds

Three types of instrument are available: drums, melody and bass. Use different colours of bricks to make music with the different instrument types.

Grid-based music making

The left-to-right position sets the timing of each musical note, the top to bottom position selects which note/pitch to play, and the colour sets the instrument. The app also lets you adjust the tempo, swing, musical key and scale for your loops.
