Percussion sound can be analyzed according to its intensity, duration, pitch (frequency), quality, and location. Frequency describes the concept of pitch. Frequency is caused by the sound's vibrations, or the highness or lowness of a sound. Frequency is measured in cycles per second or hertz. More rapidly occurring vibrations have a pitch that is higher than that of slower vibrations. Duration describes the time period over which a sound is heard when elicited. Intensity refers to the relative loudness or softness of the sound, also called the amplitude. The quality of a sound is its timbre, or how one perceives it musically. Location of sound refers to the area where the sound is produced and heard.
