Abstract
Recent research on the acoustics of percussion instruments has focussed on observing their modes of vibration and understanding how they radiate sound. Holographic interferometry, on account of its high resolution, is an especially useful method for modal analysis on a wide variety of percussion instruments. Several new percussion instruments as well as studies on some very ancient ones are described. New instruments include tuned wind chimes, Caribbean steelpans, major-third bells, bass handbells, Choirchimes, and glass instruments.
