Musical instruments in the percussion family radiate sound from many normal modes of vibration. These modes have distinctly different radiation patterns, resulting in a sound field that varies markedly with frequency and with time. Some of the modes of vibration and the resulting radiation patterns obtained from a representative number of percussion instruments, including bells, various types of drums, and cymbals, are described.
