Remember that a percussionist's role in a concert band is not just to be a "drummer!" You must learn to play a number of drum, keyboard, and auxilliary instruments with proper technique.
Many common percussion instruments fall into one (or more) of the following families.
Drums: Snare Drum, Bass Drum, Toms, Timpani, Timbales, Bongos, Congas, Djembe
Keyboard Percussion: Glockenspiel (Bells), Xylophone, Marimba, Vibraphone
Metals: Crash Cymbals, Suspended Cymbal, Gong, Finger Cymbals, China Cymbal, Ride Cymbal, Triangle, Bell Tree, Mark Tree (Windchimes), Tubular Bells (Chimes), Crotales
Other Auxiliaries: Tambourine, Güiro, Maracas, Claves, Castanets, Woodblock, Temple Blocks, Cowbell, Agogo Bells, Vibraslap, Slapstick
Learning the matched grip for concert snare drum readily prepares you to play other instruments. Specifically, instruments that use the following implements generally require matched grip: drumsticks, mallets, and beaters.
Sometimes, in order to play double-stops (multiple notes at the same time) in both hands, keyboard percussionists use 4-mallet technique, with a grip that allows for 2 mallets in each hand. This is an advanced technique that should be learned from a private teacher.
There are a few variations of grip that can be used for timpani. All are matched, and similar to the snare grip.
