Steelpan

Steelpan (also known as steeldrums or pans, and sometimes collectively with the musicians as a steelband) is a musical instrument and a form of music originating in Trinidad and Tobago.The pan is a pitched percussion instrument, tuned chromatically (although some toy or novelty steelpans are tuned diatonically), made from a 55 gallon drum of the type that stores oil. In fact, drum refers to the steel drum containers from which the pans are made; the steel drum is correctly called a steelpan or pan as it falls into the Idiophone family of instruments, and is not technically regarded as a drum or Membranophone.
