Sheet Music
This performance is using the 1912 Schirmer Edition of The Messiah. Not only is this one of the most widely known and available editions, but it also has passed into the public domain so free copies are available. There is a discussion of the copyright status of this edition, as well as a link to download the entire score at the International Music Score Library Project's Messiah page.
If you want your own copy, they can be purchased from a variety of sources for around $8-$10 (for example Amazon). We are also making available here a downloadable copy that includes the 6 choruses we are singing for this performance.
Choral Score - 47 pp, 7 MB
