Crystallophone

A crystallophone is a musical instrument that produces sound from glass.

Glass harmonica: Spinning glass disks (bowls) on a common shaft are arranged with the lower notes (larger disks) to the left and higher notes (smaller disks) to the right.

A glass harp being played in Rome, Italy. The rims of wine glasses filled with water are rubbed by the player's fingers to create the notes.

The cristal baschet

One of the best known crystallophones is the glass harmonica, a set of rotating glass bowls which produce eerie, clear tones when rubbed with a wet finger. Musical glasses, the glass harp, were documented in Persia in the 14th century.[1] The "ethereal" quality of instruments such as the glass harmonica exemplified the Empfindsamkeit and for a while, "the instrument was extraordinarily popular...[but] About 1830 the instrument fell into oblivion."[1]

The glasschord (or glasscord) resembles the celesta (a struck plaque idiophone operated by a keyboard) but uses keyboard-driven hammers to strike glass bars instead of metal bars.

The glass marimba is similar to the marimba (a stick percussion instrument with a keyboard layout), but has bars of glass instead of wood. The bars, which the performer strikes with padded sticks, are perched on a glass box to provide the necessary resonance.

A rare Thai instrument called ranat kaeo (ระนาดแก้ว; literally "glass xylophone") has been used by the Thai music ensemble Fong Naam; it appears on their 1992 CD The Sleeping Angel: Thai Classical Music.
