a waltz that never repeats, played by dice.

Live on YouTube, around the clock.

In 1792 a parlour game was published, attributed to Mozart (K. 516f): roll two dice for each bar, look the bar up in a table, and you've composed a waltz. With 11 choices for each of 16 bars there are about 46 quadrillion of them.

Dice Waltz rolls the dice live and plays the result. Every sound is synthesised in code; nothing is AI. Viewers change how it sounds by typing commands in the YouTube live chat.
