For you non-German speakers, and myself, also a non-German speaker, here is the English translation (from Google translate) of the history portion. Thanks for DFO user type85 for sharing the link— he has a cool YouTube channel you'll want to subscribe to.
This article is intended to provide a basis for the development of drum cymbals and their various metal compounds from ancient times to the present day. After a historical introduction and presentation of the important manufacturers, the second part deals with the sound properties of cymbals and the various alloys with their advantages and disadvantages.
Part I: Where do cymbals actually come from?Cymbals are of Asian origin and can be found on Assyrian monuments (2nd millennium BC). They were also part of Indonesian gamelan music in the form of tuned bronze gongs. According to Greek belief, they took away the power of demons, so they were beaten at funerals for the deceased. Western miniatures show them up until the 15th century; then they seem to have been forgotten, probably because the art of hammering them was lost. 200 years later, they reappeared in what is now Turkey and found their way into local military music with their Janissary music during the Turkish wars. Soon after, they also found their place in classical music.In the 1913 Real-Lexikon der Musikinstrumente, cymbals are defined as “a percussion instrument made of two convex bronze plates, hammered to the same thickness, about 40 cm wide, made in all sizes, without a specific pitch, with leather handles threaded through the hump.” “For special effects, the edges are gently clinked together or one of the cymbals is struck with a timpani mallet. Art music makes sparing use of this instrument; but in military orchestras and lower-ranking bands, which of course attach one cymbal to the bass drum and thus coarsen the effect, it has become indispensable.”Since then, hand-made cymbals have fascinated drummers and percussionists in Europe and the “new world” with their complex sounds, rich overtones and unique character. But what makes them so special? The starting point of every cymbal is its alloy – the metal mixture that gives it its basic sound properties.
It's long, the rest of it is below the fold:
