A drum roll is a rapid succession of single strokes played on a drum. It is a fundamental technique used in drumming and is often used to create a sense of excitement or anticipation. Drum rolls can be played on any type of drum, but they are most commonly played on snare drums and bass drums.
There are many different ways to play a drum roll. The most common technique is to use the rudiment called the single-stroke roll. This rudiment is played by alternating the left and right hands on the drumhead, with each hand playing a single stroke. The speed of the roll can be varied by increasing or decreasing the tempo of the strokes.
