A crash cymbal is a type of percussion instrument commonly used in drum kits. It is typically made of bronze or brass and produces a loud, sharp sound when struck with a drumstick. Crash cymbals are often used to accentuate musical phrases or transitions in various genres, including rock, jazz, and orchestral music. These cymbals come in various sizes, usually ranging from 14 to 20 inches in diameter. Musicians often play them in combination with other cymbals, such as hi-hat and ride cymbals, to create a fuller sound. The crash cymbal is essential for adding dynamics and excitement to a performance.
