Modular Diary – 093

The @reaktorplayer twitter account provides a seemingly endless stream of fascinating links on music theory and technology. There’s also a reaktorplayer website covering “thoughts, research and experimentation with electronic music, art and photography.” A recent tweet linked to a PDF on the Digital Harmony of Sound and Light that covers, from a slightly different angle, some of the theory that also underlies the oscilloscope music of Jereobeam Fenderson, for example.

The ‘differential dynamics’ illustrated in the article reminded me of Jerobeam’s DC-offset examples and the rose curve patterns – of which there are some nice animations in the Wikipedia article – have some similarities with the figures I was recently playing around with (again following Jerobeam’s example) using the modified STS Harmonium. For interest’s sake, the difference between the harmonium shapes and Lissajous figures is that both signals (should one restrict the number to two) have a sine and a cosine output, whereas with the Lissajous patterns one signal has a sine and the other a cosine phase.
