I am very interesting about all technical aspects of the mouthpiece. I have found great research done by Lawson USA. They name the parallel section - throat. "The average throat size of a French Horn mouthpiece is a No. 11 drill (,191"). * long throat will give more resistance than a short throat and will play with a stronger response in the mid-range of the instrument at the expense of the high - range. Obviously, a careful balance must be determined for the intended player"
