I have often heard about the "Bach" sound as it relates to trumpets. A subject of much discussion and opinion... I am wondering if anyone has an opinion as to whether there is a Bach sound in mouthpieces? And if so, is there a Schilke "sound," regarding the Schilke line of mouthpieces? Do these two different lines have any sort of characteristic sound, or do they have any tendencies toward helping achieving anything in particular in regard to tone, in and of themselves, and apart from the player? Any experiences or thoughts?
