I'm just wondering how much time to allow in my score for a tenor trombone player to switch from a bucket mute to a harmon. (I only one change, going from bucket to harmon.) I realize this is going to depend on the tempo. But if I knew what the player had to do physically, I can estimate whether there is enough time to make the switch. Is is simply a matter of pulling one mute out and putting the other one in? Or does it require some adjustment or tuning?
