A lamellophone [also lamellaphone or linguaphone, from the Latin root lingua meaning “tongue”, i.e. a long thin plate that is fixed only at one end] is any of a family of musical instruments. The name comes from the Latin word lamella for “small metal plate” and the Greek word φωνή phonē for “sound, voice”.
The name derives from the way the sound is produced: the instrument has a series of thin plates, or “tongues”, each of which is fixed at one end and has the other end free. When the musician depresses the free end of a plate with a finger or fingernail, and then allows the finger to slip off, the released plate vibrates.
The lamellaphones are classified under category 12 in the Hornbostel–Sachs system for classifying musical instruments, plucked idiophones. These idiophones are equipped with one or more tongues or lamellae that produce sound by being plucked by the performer. There are two main categories of plucked idiophones, those that are in the form of a frame  and those that are in the form of a comb .
