Here is # 7 from the Arban Conservatory Method. Called: My Own. It's an accompaniment for my trumpet students. I created the harmonization from the melody given in the method book so my students could have something along with which to practice.
Another beauty, William... very well done!
Darned sure hand with the harmonizations; fine work;
and a great idea to provide these for your students.
I agree with David. Excellently done and a sure winner to help the student trumpet musician along.
