'''MISS WHARTON DUFF'''. Scottish "marching air" (Alasdair Fraser's description). B Flat Major. Standard tuning (fiddle). AAB. Composed by [[biography:William Marshall]] (1748-1833). According to Moyra Cowie ('''The Life and Times of William Marshall''', 1999), the tune may refer to Lady Ann Wharton Duff, who married her first cousin, Richard Wharton of Orton House near Inchberry in lower Spey side. Ann was a daughter of Lord Duff of Banff
. The tune is sometimes heard transposed to the key of G major at Scottish sessions, and has been played as a wedding march. The Wharton Duffs, who married in 1809, also had three daughters, and thus the tune may have been composed for one of them.
