I've heard that compared to the 3 valve BBb tubas 4 valve BBb tubas has to be generally larger than the 4 valve because of some of the tubing on the instrument. Is this why the 3 valve tubas are usually smaller than the 4 valve tuba. Is it that the more valves that are on the horn on a bigger the horn gets? I've also heard that the more valves on the horn the more effort it will take to fill up the horn. Can someone explain?
