Not sure whether this will help or not but... I've done countless military services, balls, change of gaurd/flag/command/etc due to my father being a high up. There was a time when I was performing TAPS and a senior official saw that I was playing a trumpet and asked if I would use "bugle fingerings" (1st and 3rd valve). Besides being cognizant of the tuning tendencies, it seemed to have acheived the wanted "sound effect". Just a thought.
