This is a small rhythm game which simulates the phenomenon of "conducting ahead" in its simplest form controlled either by mouse or with the spacebar:

Where the beat is supposed to be press either "space" or move your mouse so that the lowest point is at the beat.
Your beat should be about 150-400ms ahead of the beat in the music.
To turn pages press "A" (backward) or "D" (forward).

There will be two flashes before the music starts to indicate the starting point and tempo.

You can choose between two different songs.
