The meSchuS is a large Klingon wind instrument which consists of a network of interlocking tubes. One tube terminates in the mouthpiece (ngujlep) into which the player blows (SuS). The Instrument’s pitch and timbre are modified by fingering strategically placed holes in the tubing and by moving the hands in various ways (to move the fingers in this way is to (Heng). The sound emitted by the meSchuS most resembles that of a large pipe organ, but that characerization is not really flattering to either instrument.
We first see a meSchuS used during a Kot’boval festival in the TNG episode, First Born, which aired on April 25, 1994.
