Steel pans, also known as steel drums, are musical instruments originating from Trinidad and Tobago. They are made from oil drums that are carefully shaped and tuned to produce different pitches. The surface of the drum is struck with mallets, creating a rich, melodic sound that is often associated with Caribbean music. These instruments come in various sizes and can play multiple notes, allowing for complex melodies and harmonies. Steel pans are commonly used in calypso and soca music, but they have also found their way into other genres, showcasing their versatility and unique sound.
