publications to feature the 17 stroke roll. In modern times, every infantry battalion in the British military has a rudimental Corps of Drums except for Irish, Scottish, and Rifle Battalions which feature Pipe Bands and their associated style of Scottish drumming. Scottish Scottish drum and fife signals (those differing significantly from the English) date back to at least the 17th century, when the English referred to them as the "Scots Duty." The old Scottish calls used similar rudimental patterns and drumming idioms to the English, but featured slightly different drum arrangements and fife tunes, rather than the distinctively snappy dot-cut triplet shuffle sound that pipe band drumming would use later. The Scotch Reveille that would normally accompany The Mother and the Three Camps was adapted from, or at least inspired by, the Scotch Reveilly [sic] from this pre-pipe band era. Scottish pipe bands, in their modern form, were created by the British Army around 1830. British regiments made up of Scottish clansmen married rudimental drumming with the Highland bagpipes and kilts in order to regain their independent culture. The drum rudiments were modified from British and European sources to fit with the piping idioms that had been in place for several hundred years prior. Pipe bands, and their stylistically unique drummers, saw their first widespread use during the Crimean War. They continued to be an active part of battle until World War I, after which they assumed a ceremonial role. There are currently around 60–75 Scottish rudiments played in pipe bands around the commonwealth countries and former British colonies, taking influence from Swiss, French, and American Hybrid drumming as well as traditional Scottish rhythms. American Many attempts at formalizing a standard list of American snare drum rudiments have been made. The first publication to formally organize American drumming was by Friedrich Wilhelm von Steuben at Valley Forge. He included camp duty signals in his general manual on military practices for George Washington’s troops, the “blue book” written in 1778–79, though the drum parts were listed in prose. The first America rudimental manual to have prescribed rudimental exercises in notation was A Revolutionary War Drummers Book, also from 1778, which displayed 20 exercises that can be taken as rudiments as well as "drum beatings" such as the piece Valley Forg [sic]. This was followed by Ben Clark's manual on military drumming in 1797 and David Hazeltine's book Instructor in Martial Music
