where can i find cheap or free sheet music?

Try 8notes —a freebie
I buy a lot of good stuff on MusicNotes—various arrangements available.

Also SheetMusic

i found a site that Mr. Smith told me about called jwpepper.com you can listen to the music. go and find the search word choices and select advanced string orchestra. then scroll down until you find a song called Black Sea it is awesome. i think we could pull it off to. Mr. smith would have to order it for us though
