Struck

Directly struck membranophones is one of the sub-categories of musical instruments found in the Hornbostel-Sachs system of musical instrument classification. The type of membranophones or drums found in this group are those instruments that produce sound when struck directly by the performer. The membrane of these drums is hit with a stick, the hand, or something else. Drums that produce sound by means of plucking an attached string or by means of friction are grouped in a different category.
