Are you a Finesse or a power player.
For years I was a power player. When I played lead with a big band I would really lay it down. In a concert band, I would push the section and sometimes the leader.
In recent years, I've found that finesse is a better way to lead and play in general. Even in a fanfare, it doesn't have to be powerful.
In the opening to the Arutunian(sp?) Big chance to play powerfully but, not really the best idea. When it goes up to the B-flat I used to push and fill the hall. Not any more. Maybe quieter is better.
In the Hummel, third movement, in the minor section. It goes up to a high C. Some people even trill the B before and really nail that C. Try as it goes higher backing off.
Just some musical thoughts.
