A Music Pi

 

This piece of music has been written to celebrate Pi Day, the 14th March 2017.

The violin drone follows circular functions Sin modulates the pitch and Cos the volumes of each instrument. The cycles should feel a bit like breathing! The piano uses the digits of the decimal expansion of Pi to generate the notes of the chords and their timing.

The picture evokes Archimedes approximations of Pi with polygons approaching a circle.

I am not entirely happy with it, but it needs to be out for tomorrow. One day I will improve it.
