Mark tree

[1] It consists of many small chimes—typically cylinders of solid aluminum or brass tubing about 3/8" in diameter—of varying lengths, hung from a bar.

They are played by sweeping a finger or stick through the length of the hanging chimes.

They are typically mounted in pitch order to produce rising or falling glissandos.

[4] Mark trees are colloquially called wind chimes in some modern repertoire.

However, the mark tree and wind chimes are two separate instruments, differing in construction and manner of sounding.
