Funk drumming creates a groove by emphasizing the drummer's "feel and emotion", which including "occasional tempo fluctuations", the use of swing feel in some songs (e.g., "Cissy Strut" by The Meters and "I'll Take You There" by The Staple Singers, which have a half-swung feel), and less use of fills (as they can lessen the groove). Drum fills are "few and economical", to ensure that the drumming stays "in the pocket", with a steady tempo and groove. These playing techniques are supplemented by a set-up for the drum kit that often includes muffled bass drums and toms and tightly tuned snare drums. Double bass drumming sounds are often done by funk drummers with a single pedal, an approach which "accents the second note... deadens the drumhead's resonance", which gives a short, muffled bass drum sound.
