The '''glass harmonica''', also known as the '''glass armonica''', '''glass harmonium''', '''bowl organ''', '''hydrocrystalophone''', or simply the '''armonica''' or '''harmonica''' (derived from {{lang|grc|ἁρμονία}}, ''harmonia'', the [[Greek language|Greek]] word for harmony),<ref>{{OEtymD|harmonica}} {{OEtymD|harmonic}}</ref><ref>{{LSJ|a(rmoni/a|ἁρμονία|ref}}.</ref> is a type of [[musical instrument]] that uses a series of [[glass]] [[bowl (vessel)|bowls]] or goblets graduated in size to produce musical [[pitch (music)|tones]] by means of [[friction]] (instruments of this type are known as [[friction idiophone]]s). It was invented in 1761 by [[Benjamin Franklin]].
