嘴唇
许多布鲁斯琴手（包括我）选用所谓的倾斜式含琴法。也就是把口琴的前面向下倾斜大约45度。吹奏单音的口型由下嘴唇的曲线自然形成。这种方法解放了上嘴唇使它可以放在上盖板的任何位置。在使用舌堵法时这种含琴法也很有用，因为口琴的倾斜使你可以使用舌头平坦的上部代替舌尖。这使得一些舌堵孔技术比如pulls（后加伴奏？）和五孔八度和声奏法更加容易。同时由于舌头的覆盖更加均匀，音色也会有所改善。
All of this is what I call natural tone. Your goal is to create a warm, round sound from every note that you play. If you hear that a note sounds flat in pitch, your tongue is in the way. Experiment with tongue placement to raise the pitch of the note. If you hear that a note sounds airy, your tongue is in the way. Experiment with tongue placement to get rid of as much airiness as possible. If you hear that your tone is thin and lacks fullness, follow all of the directions above to open your embouchure to achieve good tone.
以上所述就是我所谓的自然音色。你的目标是把每一个音吹得温暖圆润。如果发音偏低，那就是你的舌头挡路了，试着改变舌头的位置把音调提高；如果琴声虚弱空洞，那也是你的舌头挡路了，试着改变舌头的位置尽量避免这个毛病；如果琴声单薄，不够丰满，就试着按照上面的要求去做直到找到好音色
