Project Gutenberg – Bibliographic Record – Beethoven’s String Quartet No. 14 in C-sharp Minor, Opus 131 for download in several formats, including the easy to print PDF. They’ve got other songs on here, too. I’m hardly skilled enough to play these, though my sister-in-law Becca could probably ‘pound these out.’ [not really what you want to do with a piece like this – but I was going for the idiom].
