Making Sound and Composing Rhythms

Movies on these pages require the free QuickTime plug-in.

We started by inventing sound makers with a variety of materials, motors and crickets. Then we experimented with how to make them play. We triggered them to make sound in a dark room, when light passed in front of a light sensor, and we triggered them to make sound in a bright room, when a dark spot passed in front of a light sensor.

Next we composed rhythmic patterns for the instruments on a paper cylinder than spins slowly on a record player. In the dark-room version, we hung a lightbulb inside the cylinder and poked holes in a black paper cylinder. In the light-room version, we taped black foam onto a white paper cylinder.
