He had lessons in piano, organ, clarinet, and bassoon, but North Texas virtuoso Robert Froehner is self-taught on the instrument that made him a featured performer with symphony orchestras: the Craftsman saw. Froehner's musical saws range from a 16-inch "piccolo saw" to a 36-inch "bass saw," all hardware-store models ordinary except for the sound Froehner coaxes from them. Wikipedia describes the musical saw sound as "an ethereal tone, very similar to the theremin or a woman's clear voice."
