I don't know what string quartet this really is, but it certainly isn't Haydn's Op.1 No.3, which in any case is in D major, not C minor. I think it's probably one of Joseph Jongen's quartets, but his opus 1 wasn't string quartets as far as I know (op.2 and 3 were). In any event, this attribution to Haydn is certainly erroneous, and I'm changing it and removing the opus and number information.

Your right... I think Sibley made a mistake (the url Peter originally gave was gone), and later rectified it. Thanks for bringing this to our attention :) --Feldmahler 13:31, 26 November 2006 (EST)
