Song bells

Song bells are a musical instrument in the Keyboard [percussion instrument|keyboard percussion] family. They are a mallet percussion instrument in the metallophone family that is essentially a cross between the vibraphone, glockenspiel, and celesta. They have bars made of aluminum.
They sound one octave down from the glockenspiel, or one octave above concert pitch and generally have a range of octaves. Song bells have been made by various makers at different times but were first introduced by J. C. [Deagan, Inc.] in 1918 and manufactured by the company until 1924.
