Many power metal drummers play double bass patterns with either two bass drums, or utilize a double bass pedal; using them to play a constant stream of sixteenth notes (semiquavers) with snare drum accents on the beat, a style not restricted to, but most often associated with, power metal. The style was used by drummer Ingo Schwichtenberg of Helloween, setting a blueprint for many other drummers to follow. Others, such as the drummers of Blind Guardian and Iced Earth, use a more thrash metal style of drumming with rapid bursts of double bass that involve three to six beats with the double kick.
