"Delaware Hornpipe" is an American hornpipe in G Major. The parts are played AABB. The name 'Delaware' derives from Thomas, Lord de la Warr, the first Governor of Virginia, a courtier and soldier who as a young man had been knighted by Queen Elizabeth. At first the bay was named for him, then a river emptying into it was discovered and also given the same name, and finally the region was named for the river. A very similar (nearly identical in most measures) hornpipe is to be found in the large mid-19th century music manuscript collection of County Cork cleric and uilleann piper Canon James Goodman as an untitled "hornpipe". "Delaware Hornpipe" was one of the tunes cited by Lettie Osborn (New York Folklore Quarterly) as having commonly been played for dances in Orange County, New York, in the 1930's. It was printed in Oliver Ditson's The Boston Collection of Instrumental Music (c. 1850), Ryan's Mammoth Collection (1883) and Cole's 1000 Fiddle Tunes (1940).
