Circles and Euclidean Rhythms: Off the Grid, a Few Music Makers That Go Round and Round

Loopseque on the iPad. Courtesy the developer. We continue our 3.14 celebration with a round-up of circular logic. There’s no reason apart from the printed score to assume music has to be divided into grids laid on rectangles. Even the “piano roll” as a concept began as just that – a roll. Cycles the world around, from a mechanical clock to Indonesian gamelan, can be thought of in circles. Imagine an alternate universe in which Raymond Scott’s circle machine – a great, mechanical disc capable of sequencing sounds – became the dominant paradigm. We might have circles everywhere, in place …


Flickr Find: Harmonic Patterns on a Playground

Photo (CC-BY) Jan Tik. We celebrate 3.14, PI day, with some selections of mathematics, music, and visualization… Sometimes the results resemble scores, sometimes toys, and sometimes – more rarely – real musical instruments. But part of why I love computing as a window into music is its ability to visualize music’s mathematical beauty. I happened across this image from Flickr. It’s a chalk pattern on pavement for a children’s game (I’m not actually sure what game). But the math-compelled photographer found in it musical, harmonic intervals. I’ll have to sketch a little Processing and Pd design that plays with this …


Pythagoras, Upcoming iPad App, Recasts Frets to Make them More Harmonic

To celebrate what in the US we call 3.14 or PI day, today I’m offering stories that deal with mathematics and circles. First up, an app named for the great philosopher who is credited – even if perhaps ahistorically so – with finding that ratio and ratios in harmonies. Technology has long introduced innovations that make playing easier for specialists and non-specialists alike. Just ask anyone who plays an instrument like the guitar – frets, and the simplified notation that went with it, go back centuries as a means of allowing more people to make music. Developer Rob Fielding wants …
