A musical saw, also called a singing saw, is a hand saw used as a musical instrument. Capable of continuous glissando (portamento), the sound creates an ethereal tone, very similar to the theremin. The musical saw is classified as a plaque friction idiophone with direct friction (132.1) under the Hornbostel-Sachs system of musical instrument classification, and as a metal sheet played by friction (151) under the revision of the Hornbostel-Sachs classification by the MIMO Consortium.
