'''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, daughter of Lord Duff of Banff, who in 1809 married her first cousin, Richard Wharton of Orton House near Inchberry in lower Speyside. The Duffs had three daughters, however, so the tune may also have been named for one of them.
The tune is sometimes heard transposed to the key of G major at Scottish sessions,
and has been played as a wedding march.
