BitWiz Harmonic Series Code

Saturday, May 6th, 2017


BitWiz is a $0.99 app that lets you run single line C code music generation algorithms. I used it to perform this piece by selecting code in sequence and using the X-Y manipulation when it was a part of the code. This software from Kymatica is for the iPad. The analysis shows that at least the first section is clearly non-12 equal. I didn’t analyze the rest, however, it seems to me to be almost next to impossible for a single line of code to generate something as unnatural as 12 equal.
