Shuebruk wrote a trumpet player’s guide to the instrument which included 5 short books. The first three were technique and daily exercise books, and the last two were duets. The duets books are available here for the duets for two cornets, and on this page for duets for trumpet and trombone. The final duet in this collection includes a piano accompaniment and is meant for concert performance. These duets are quite a bit more involved than the duets for two cornets, but are very accessible by today’s standards.
