"Acoustics of Caribbean Steel Drums"

Dr. Thomas Rossing
Physics Department
Northern Illinois University

The Caribbean steelpan is probably the most important new acoustical musical instrument to develop in the 20th century.  In addition to being the foremost musical instrument in its home country, Trinidad and Tobago, steel bands are becoming increasingly popular in Europe, North America, and some Asian countries as well.

We have studied the modes of vibration of steelpans by several makers using holographic interferometry. Nonlinear coupling between the different note areas of the drum is important in producing sound.
