This makes it a surprisingly tunable instrument, even though it has no strings, no reeds, and no drumheads.

In practical performance, the musical block is a sound effect instrument. It cuts through a mix. It provides the distinctive "clopping" sound in a rhythm section, the woodpecker-like accent in a Latin percussion arrangement, and the hollow kerplunk in a film score's tense scene. You are most likely to hear it in one of three contexts. In a concert percussion ensemble, a set of five pitched temple blocks sits on a table, played with two mallets for melodic patterns. In a drum kit, a single, loud plastic jam block is mounted on a cymbal stand, used as a substitute for a woodblock or as a unique accent in funk and rock grooves. In a school band room, a row of wood blocks on a single stand is the
