Christmas music is my favorite kind of music to teach children and adults alike. One of the first Christmas songs that I remember singing a harmony part with my mother was Star Bright (or Estrella de Luz) by Lorin F. Wheelwright, a beautiful song with 2 part harmony and verses in Spanish as well as English. Not only that, but she played it on her guitar which made it even more wonderful.
I found the sheet music for Star Bright published in the LDS Instructor Magazine in October 1959. The online copy I found is so discolored that I decided to fix it with my photo editing software and I added the guitar chords to it. No flipchart for this one, I just wanted a place to share this copy of the sheet music for anyone looking for a sweet Christmas song other than what is in the Hymn book or Children's Songbook.
