Used to describe a feeling of two or more musicians playing in such a way that they are in perfect sync in the way the music feels . “In the pocket” means playing a groove with other musicians that feels really, really good, with the pocket being an almost-magical place where the musicians feel almost telepathically connected in time and feel.

The act of playing a good-feeling beat on the drums (or another instrument).

Another word for beat, but with the implication of the beat feeling good to the musicians and listeners.

A mechanical device that produces an evenly-placed short sound (typically a click or beep) in an exact interval of times per minute. The frequency of the sounds is measured in “beats per minute” and is used to tell musicians the exact tempo of the music. These devices come as specific products (metronomes) , or as computer programs/phone applications that generate a click digitally.

The specific speed of the music being played.

Used several ways by musicians, time generally means the tempo or beat of the music being played. It also is used as a synonym for “beat” by musicians. (Telling a drummer to “play time” or “keep time” means “play a steady beat.”) “Time” is also used to describe the ability of a musician to play with steady, good-feeling tempo (e.g., “She has good time.”).

A secondary hi-hat that is not in the standard position on the drum-set but mounted or placed elsewhere. A remote hi-hat is either controlled with a foot-operated cable or mounted in a fixed, closed position.

Two bass drums. Used to describe both a drum-set (a “double bass setup”) or a rhythm played with two bass drums (“double bass groove”).
