STACK//SOUND

Build your tower. Compose your sound.

Round over

0

·

Place the moving block with a click, a tap or Space. Whatever hangs over the tower falls off, and the next block is narrower. A perfect drop builds a combo, and the fourth perfect drop in a row widens the block. Every block plays a note: the more precise, the cleaner the sound; as the tower grows, beat, bass, chords and arpeggio join in. After the round you can play back your tower as a piece and download it as a MIDI file. Your record is saved in this browser.

About the experiment

A moving block slides over the tower – drop it at the perfect moment. Anything that hangs over falls off, so every mistake narrows the next floor, while perfect drops build a combo and widen the block again.

The tower is an instrument: every block is a pentatonic note locked to the pulse, so even random clicks sound melodic. A perfect drop rings clean, an edge hit is short and percussive, and as the tower grows, beat, bass, chords and arpeggio join in. After the round, play your tower back as a piece and download it as a MIDI file.
