The glass harmonica, also known as the glass armonica, bowl organ, hydrocrystalophone, or simply the armonica (derived from ἁρμονία harmonia, the Greek word for harmony), is a type of musical instrument that uses a series of glass bowls or goblets graduated in size to produce musical tones by means of friction (instruments of this type are known as friction idiophones).
