One definition is a sound that is produced by one object striking another. Percussion instruments are musical instruments that produce sound in this manner. There are two types: ones that have a vibrating membrane (i.e., a drum head), and ones in which the whole object vibrates, such as claves, cymbals, mallet percussion instruments, steel pans, and brake drums. Dr. Zero is using a primitive form of drumspeak to describe percussive sounds.

One of the sections of the orchestra.
Led by a principal percussionist, who is a usually a mallet player or a tympanist, but can also be expert in the membranophones. The Principal is the boss and gets the choice of instrument when the librarian delivers the parts.

The Percussion Section consists of three to five (sometimes more) people and is supported on tour by a large truck.

The Percussion Section often go drinking with the Brass Section, and laugh at the Babycham-drinking Woodwind and String sections.

Everyone knows, in their heart of hearts, that the other sections exist merely to support the Percussion.

Percussionists tend to have strong wrists and biceps (from too many paradiddle exercies, and lugging all that heavy artillery around).

Most percussionists join the section because, damnit, they want to be heard.
