A mark tree (also known as a chime tree or set of bar chimes) is a percussion instrument used primarily for musical colour. It consists of many small chimes – typically cylinders of solid metal approximately 6 mm (one-quarter inch) in diameter – of varying lengths mounted hanging from a bar. The chimes are played by sweeping a finger or stick through the length of the hanging chimes. They are mounted in pitch order to produce rising or falling glissandos.
The mark tree is named after its inventor, studio percussionist Mark Stevens. He devised the instrument in 1967. When he could not come up with a name, percussionist Emil Richards dubbed the instrument the mark tree.
The mark tree should not be confused with two similar instruments:
Wind chimes are mounted in a circle with a hanging beater strung in the center, and may be solid or hollow and of many materials, while the mark tree is mounted in a linear fashion, and is normally of solid metal bars.
The bell tree is a set of graduated cup-shaped bells mounted vertically along a center post.
