Abstract:
The cymbal – an instrument which evolved in the distant past and yet remains vibrant in today's world of music, celebration, and religious ceremony – is examined through a lens of old-world manufacturing techniques and application of modern manufacturing technologies. Metallurgical analysis (chemistry, metallography, and hardness), of various stages of cymbal production is presented. Metal alloying, casting, heat treatment, and forming techniques and their effect on cymbal aesthetics and sound will also be discussed.
