What's in a Name, Zoolophone

Like xylophones and glockenspiels, the Zoolophone is an instrument with tuned metal bars that produce sound when struck. The tone and amplification it makes depends on the shape of the instrument itself.  A zoolophone can be thought of as a xylophone with keys shaped like animals, where different shapes have different sounds.

Most zoolophones require hand-crafting to get resonant frequencies and amplification correct. They use rigid geometries, like bars and hand-drilled dimples on their undersides to create predictable sounds.
