If there is a single holiday collection that is worth $1000 and you can get it for 12 bucks, this is it.
GE Holmes’ Christmas Carols for Brass Quartet is a classic, I have played from it every single year since I started playing the trumpet. We use them at Church services, background music, carol singalongs, you name it. There is so much use for these it is crazy. It has parts for Trumpet 1 & 2, Horn, Trombone/Tuba/Baritone. They have options built in intros, and you just turn the page and play.
You probably know these, but if not, there are samples to the left. Give them a look then grab an immediate PDF download above.
