Another use of cymbals is the suspended cymbal. The profile affects the pitch of the cymbal&colon; higher profile cymbals have higher pitch. A cymbal is a common percussion instrument. Wooden timpani sticks are also occasionally used to play the suspended cymbal. All throughout this period Cameron continued using DW pedals, cymbal, and snare stands. The album begins with the bang of a gong (tam-tam) and cymbal washes. A gong, generally, is a large hung cymbal with a nipple. A cymbal stack produces a different sound to that produced by either cymbal individually. Typically, this is combined with a ride cymbal and hi-hat in syncopation. Most commonly, the drummer plays quarter notes on the crash cymbal or China cymbal. As the tin content in a bell or cymbal rises, the timbre drops. The edge or rim is the immediate circumference of the cymbal. It is often used for playing the bell of a cymbal. The bell produces a higher "pinging" pitch than the rest of the cymbal. A "China splash" cymbal is typically or smaller.
