percussionist who creates and accompanies music using drums

A drummer is a person who plays the drums as a job or as a hobby. This can be someone who plays drums in the military, in a band or as a session musician. A session musician is someone who plays an instrument in a band when no one else is available. A drummer keeps the beat so their role is a hard and important job. Without a drummer, the band would find it hard to keep in time.
