For Christmas one year, my choir sang Sure On This Shining Night, composed by Morten Lauridsen. It's a beautiful piece of music, and it got me hooked on Lauridsen's other works. O Magnum Mysterium started as a choral piece, but versions for violin and orchestra and violin and piano were commissioned specifically for Anne Akiko Meyers. The solo violin and piano version is shown here.
I've ordered the sheet music for this and hope to try learning it during the little days between Christmas and New Years. Wish me luck!
