This is a track I recently made entirely in Sonic Pi (other than basic mastering). It is in a modified A = 444 Hz, just intonation scale, and is based on the solfeggio scale and four repeating Fibonacci patterns, driven by a couple of algorithmic functions. It took me many months of coding to learn the theory behind it and then develop and code the algorithm. If the random seed is changed, then it generates related but different pieces with a similar theme. Changing tempo, rest lengths, synths etc. give a lot wider variation. I hope you enjoy it.
Other than SoundCloud, it is on Spotify and YouTube Music, and possibly now on other streaming sites through DistroKid.
