Playing second or third trumpet in a symphonic setting requires some pretty low and loud playing. Three sounds are required--quasi trombone, quasi horn and trumpet as well as complete control over dynamics. In order to get a matched section sound the lower parts need to be louder than the principal, which adds to the fun factor of playing low notes. The Vulgano part in an early Baroque five-part trumpet ensemble consists of a g below the staff. Better than rum for head-rushes and cheap, too.
