I found the original score on line which was originally written for a keyboard instrument. After starting on the piece I realized that two melodic lines could not be performed by only two trumpet players so I shared the work load among three players. Dynamics and articulations were also added for more musicality.
I think you will find this arrangement very satisfying once you have the notes and tempo down.
