Cymbals are a percussion instrument. Modern ones consist of round plates of indefinite pitch. However, small cup-shaped cymbals of ancient design sound a definite note.
Cymbals are used in orchestras and bands. They, along with drums, form the modern drum kit. Most basic drum kits contain at least one suspended cymbal and a pair of hi-hat cymbals.
The bell is the center of a cymbal. Its sound is of a higher register than the rest of the cymbal when hit with the side of a drum stick. The remaining cymbal surface is the bow, which gives off a ping sound.
The rim is what gives off the crash sound. The edges vibrate more when hit so the sound is louder. Cymbals come in various sizes, materials, and price ranges. Whatever kind of cymbals you want, browse eBay for the best price in new and used cymbals.
