A steel drum is a musical instrument originating from the Caribbean, particularly associated with the island of Trinidad and Tobago. It is made from a metal barrel that is carefully shaped and tuned to produce different pitches. The surface of the drum is struck with mallets, creating vibrant and resonant sounds that are often used in calypso and reggae music. Steel drums come in various sizes and tunings, allowing for a range of musical expressions. They are typically played in groups, known as steel bands, which can include multiple drums and other instruments. The unique sound of the steel drum has gained popularity worldwide, making it a symbol of Caribbean culture.
