Free Sheet Music
There are many websites on line with free sheet music. Here are some of my favorite resources:
The wikifonia foundation host free and legal lead sheets on their website. There are many popular songs and jazz available . Users can transpose songs, and submit their own lead sheets. You can also download .xml files to use in Finale, Sibelius, or Musescore.
While difficult to navigate, this website does have quite a few Public Domain Compositions available.
This website has many free solos for most instruments. There are also some arrangements for purchase, but mostly free.
Much Like 8notes.com, this website has many free arrangements for various instruments.
Band Link is the a website for South Carolina School Bands. They host some band warm up, arrangements, as well as some solos for various instruments.
Scans of many public domain scores, sheet music and arrangements.
