The Triangle is a simple steel rod, bent into the shape for which it is named. Although the triangle is among the smallest of orchestral instruments, it has a very clear, tinkling sound that cuts through even very loud music. The triangle does not have a distinct pitch ; its tone quality varies according to where, and how hard, you strike it.
