Inconsistencies in a drummer’s tempo often occur during musical transitions. For instance, moving from the hi-hat to the ride cymbal to change the sonic texture alters the drummer’s positioning behind the kit, which can cause changes in the tempo. Dynamic changes can also alter timing—drummers often tend to rush when they get louder and slow down when they get quieter. And changing the feel or style of a groove, such as transitioning from half-time to double-time or from straight 8ths to swing, are both likely places for the tempo to shift. Practicing transitions between grooves is as important as practicing the grooves themselves.
