Drum and bugle corps
Tenor drums, or "tenors" are actually a set of 4 or 5 drums attached together, designed to be played all by one person. The different drums have different pitches that can be played in sequences to produce crude melodies. This instrument has a sound like "oh" and a noticeable pitch, and the sound quality can change depending on the type of stick used to hit the instrument. Corps can have between 3-5 musicians playing these.
