The Sound of a Pendulum Wave – As Bounces with Harmonic Series Pitches – Bounce Metronome Pro



http://bouncemetronome.com/features/pro/theremins-rhythmicon This brings together ideas from Theremin’s Rhythmicon and the lovely pendulum waves. This version has starts at 52 beats per measure, going up to 67 beats per measure. Each part plays one of the harmonics in the harmonic series (from 1 up to 16).

To add some extra interest, each part changes in volume through a cycle of 16 notes, so that the emphasis changes so sometimes some are picked out and sometimes others.

For more videos of the rhythmicon (with sound) or to try it out yourself see: http://bouncemetronome.com/features/pro/theremins-rhythmicon

This is an option for the Rhythmicon in the new Bounce 4.3 release.

DETAILS

A pendulum wave has pendulums with strings of varying length, which swing back and forth each at a different rate to make these beautiful patterns.

This video uses bouncing balls instead. The balls bounce on the horizontal plane at the exact moment the pendulum crosses the vertical line for the pendulum waves – so it plays in the same rhythm as a pendulum wave.

Theremin’s rhythmicon uses rhythms, varying from 1 to 16 beats per measure, played on harmonics 1 to 16. So it is much the same idea you just need to start at 52 beats per measure instead of 1.

There are several other sonified pendulum waves on youtube including:

For another sonified pendulum wave see the video at the bottom of http://www.stephenjamestaylor.com/sjt/max-msp.html
- his simulation is matched up almost exactly with a film of a real-world pendulum wave :)

Since I can’t release the source code for Bounce Metronome, I can’t include Sorlo in the installer, but have included it in an extra sprites package “plug in” you can download after you install the program.
