A steel drum, also known as a steel pan, is a musical instrument originating from Trinidad and Tobago. It is made from a metal barrel that is carefully shaped and tuned to produce different musical notes. The surface of the drum is struck with mallets, creating a rich, resonant sound that is often associated with Caribbean music. Steel drums come in various sizes and tunings, allowing for a wide range of musical expression. They are commonly used in genres like calypso and soca, and have gained popularity worldwide. The instrument is often played in ensembles, contributing to vibrant performances at festivals and celebrations.
