====Timpani====
{{main|Timpani}}

Like the marching mallet percussion, [[timpani]] were marched when drum corps required everything to be marched. The marching timpani were made of fiberglass, and were played by a four- or five-man line (similar to a modern-day bass drum line). The timpani were cranked by a handle sticking up on the side of the drum. Sometimes intricate, complex music was made using the possibilities of 4 or 5 players. While one man was cranking/tuning, another was playing. To help with intonation issues, some timpani came equipped with tuning gauges.{{Citation needed|date=September 2020}}

During concert pieces, timpani were often grounded momentarily, using a tripod leg system. Eventually, in 1981, like the mallet instruments, timpani were allowed to be grounded paving the way to the modern-day [[front ensemble]]. Some corps, like the [[Blue Devils Drum and Bugle Corps]], started using balanced action timpani played by only one player to open up new positions for other members. However, not all corps could afford a new set of concert timpani and simply grounded their marching timpani.<ref name=":0" />
