"Melancholy Martin", also known as "Mártan Dubhach" is an English Country Dance or Irish slip-jig tune in 9/8 time and A Major. The parts are played AB (Sharp) or AABB (Karpeles, Kennedy, Levey, O'Neill, Petrie, Raven). Irish versions entered the repertoire through George Petrie's Ancient Music of Ireland (1855). Petrie points out that the provenance is unclear. Irish sources seem to predate English ones, which seem to stem from Cecil Sharp's Country Dance Tunes (1909) and Sharp noted that he had the tune from Petrie. It was printed in P.M. Haverty's One Hundred Irish Airs vol. 1 (1858), Karpeles & Schofield's A Selection of 100 English Folk Dance Airs (1951), Kennedy's Fiddler's Tune-Book: Slip Jigs and Waltzes (1999), Levey's Dance Music of Ireland, 2nd Collection (1873), O'Neill's Music of Ireland (1903), Krassen's O'Neill's Music of Ireland (1976), Petrie's Ancient Music of Ireland (1855), Raven's English Country Dance Tunes (1984) and Sharp's Country Dance Tunes (1909).
