After writing yesterdays article on the Musical Instrument Museum in Brussels, I decided to have a go at creating the glass harmonica sounds with Sonic Pi, and ended up being able to play Mozart’s Adagio in C which he wrote especially for the instrument. Not bad when the whole thing is generated from the :ambi_glass_rubbed sample supplied with Sonic Pi
You can read the article as to how it was done, and down load the program in the accompanying article here.
It also contains a link to the an audio recording of the program output and to a youtube video of Sonic Pi playing the piece here.
