"The Ten Pound Fiddle" is a Scottish and Canadian reel in A Major. The parts are played AB (Cranford, Hunter, Phillips, Skinner) or AAB (Martin).
It was composed by Scottish composer and fiddler James Scott Skinner (1841-1927), who recorded it in 1910.
The 'Pound' in the title is not a weight but the British monetary unit (perhaps the cost of the instrument which would be equivalent to about $1,500 USD today).
It was printed in Cranford's Winston Fitzgerald (1997), Hunter's Fiddle Music of Scotland (1988), Martin's Traditional Scottish Fiddling (2002), Phillips' Fiddlecase Tunebook: British Isles (1989), Skinner's The Scottish Violinist (1900).
It was recorded by Dave Swarbrick on Smiddyburn and Flittin' (1981), Angus Chisolm on The Early Recordings of Angus Chisolm (1978), J. Scott Skinner on The Strathspey King (remastered - 1975) and Alex Green on Caledonian Companion (1975).
