tubaphone
Quick Summary
The tubaphone is a musical instrument that is a softer-toned variation of the glockenspiel. It is used in military bands and features metal tubes instead of the tuned steel bars found on a glockenspiel. The glockenspiel itself is a percussion instrument, originally a set of graduated bells, which later evolved into a set of tuned steel bars, also known as a metallophone. The glockenspiel's bars are arranged in two rows, similar to the black keys on a piano, and it typically has a range of two and a half to three octaves. The tubaphone's unique construction with metal tubes contributes to its distinct, softer tone.1
