Yesterday’s Thing was a breath controller- blow into it to control the volume of today’s Thing: the Fish Organ, so named because the box used to contain smoked fish. And it sounds a little something like this.
The keyboard is copper tape cut to shape. It’s tuned (approximately) to the twelve tone Just scale based on 2’s, 3’s, and 5’s. When the little red plug is plugged into the "No breath" jack, the thing plays at full volume without the breath controller.
