Cymbals (Fr. cymbales; Ger. Becken; Ital. piatti or cinelli; Por. pratos), are a modern percussion instrument. Cymbals consist of thin, normally round plates of various cymbal alloys. Most modern cymbals are of indefinite pitch (tuned sets have been manufactured but are rare), whereas small cup-shaped cymbals based on ancient designs sound a definite note. Cymbals are used in modern orchestras and many military, marching, concert and other bands. They are one of the two instrument types that form the modern drum kit, the other of course being the drum, and as such are a basic part of much contemporary music. Even the most basic drum kit normally contains at least one suspended cymbal and a pair of hi-hat cymbals.
