Harmonic Series

Harmonic Series is a set of tracks I made in 2012 by generating pure sine waves at harmonic frequencies and arranging them in various sequential patterns. The sine waves were generated by writing some code in Mathematica, creating sets of tones with different harmonic ratios and amplitude envelopes, and the resulting files were sequenced in Reaper. At the time there was a web app that created polar coordinate spectrograms of music you uploaded to it (I forget what it’s called, and can’t find it now), with which I made some images of these tracks – these are on the album artwork. Below are some recent spectrograms of the same tracks made with Sonic Visualiser, using a setting that more accurately identifies frequencies, which are visualised as thin lines of colour instead of wide bands. Click images to enlarge – they look best at 100% or bigger.
