The crowds want to hear the magic that you can bring to their ears. Compose as precisely as possible - no crotchet or quaver can go to waste.


The dot marked with white at the top of the screen shows the 'instrument' that you have selected. The white box moving across the screen shows you where the current musical 'beat' is.

By pressing the left or right arrow key, you change the selected instrument. By pressing space, the instrument starts playing at the current beat, and the coloured boxes show the notes of the instrument. To pass the level, you have to have all the instruments be playing at the same time, but without any of their notes overlapping.
