Here's a fun and easily accessible arrangement of the holiday classic “Feliz Navidad” for Trombone duet. Both parts remain active throughout. The melody stays with the first part while the second part keeps interesting, at times with rhythmic accompaniment and at other times in direct harmony. This will work well with young players on either part.
Scored for 2 Tenor Trombones, Bass Trombone will work just fine on the second part as well, though nothing goes higher than the D above middle C, nor below the G at the bottom of the staff.
A great option for beginning players to enjoy playing Christmas music as duet partners!
