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 melodic sounds that are often associated with Caribbean music. These instruments come in various sizes and can play a wide range of notes, making them versatile for different musical styles. Steel pans are commonly used in calypso, soca, and other genres, and they have gained popularity worldwide for their unique sound and vibrant cultural significance.
