SawToothNoise

For my 16th sketch of Mathober2025 coded in SonicPi, SawToothNoise takes the 21st Prompt of “Sawtooth” & 30th Prompt of “Minor” and uses it to code and manipulate the audio through a minor scale and having sawtooth adjust the rate.

Poetry

Even Though the sound is in stereo
The relationship of the lines go
From most to least
But doesnt mean
That this scene
Ends with an ease
