美丽的,mainly depends on reasonable and adequate lip vibration and correct and reaso纳夫莱嘴形状控制。在公司ndition of relatively stable breath, the tightness of lip muscle, the strength of breath and the position of flute head directly affect the timbre and pitch of saxophone. Often there are such situations: some beginners can not correctly use the combination of mouth shape and breath, only know how to blindly blow when playing treble, and there is a phenomenon of drumming gills, blowing a lot of air, and can not always blow the treble up and down, the result is not ideal, even the tone is explosive and empty; some are tense and can not relax. And pinch the mouth forward, the result is that the bass can not come down, resulting in a miscellaneous tone, stuffy. All these problems are caused by incorrect mouths. Incorrect lip shape will lead to the lip muscles can not function properly, the drum and mouth pinch make the playing lose the best control, so it is difficult to obtain the ideal timbre. The correct way is to relax the facial muscles while playing the saxophone, keep the natural playing state, place the flute head in the middle of the mouth, and place the upper teeth firmly on the top of the flute head, about a third of the time. The flute head should be fixed so as not to move in the mouth when playing. The position of the flute head is fixed by the upper teeth and lips. Beginners can put a rubber paste in the right place to help the upper teeth find the fixed position of the flute head, not more than a few days at most, in order to prevent excessive dependence. The lower lip is slightly rolled over the lower teeth, and about half of the lower lip muscles are inverted over the lower teeth. The amount of muscle inversion in the lower lip depends on the fullness of the lower lip. According to their own conditions and experience. If there are too many inverted muscles, the timbre will be very dull and stiff. If there are too few inverted muscles, the timbre will be difficult to control. The lower lip is usually contained in one third to half of the whistle. In this way, the upper and lower lips are generally relative, and the lip muscles and the horn muscles contract toward the corner of the mouth at the same time, so that the lips have both closing force and opening force, and maintain appropriate pressure on the whistle piece, which need not be too tight, should be relaxed and natural.
