Can I ask my voice teacher about the differentiation of head voice, pharyngeal voice and falsetto?

I don't dare to judge your voice, but I can explain the terms you mentioned, the head voice is the high position, in the center of the eyebrow. You close your mouth and hum, pinch your nose, if the sound is buzzing in your nose, you have found the head voice. If you can't hum when you pinch it, it's still low. No matter what kind of singing needs high position, with it to avoid the throat this part of the organ tension, and with high position sound is more concentrated, penetration will be good, the voice translucent. Pharyngeal tone is the term for American singing, a standard Italian school of sharpness, pharyngeal tone is the pharyngeal wall of the closure, leaning inward to solve the problem of the high notes, but it has to be in line with the closure of the vocal folds, the vocal folds have to be pulled tightly, as if the strings of the violin have to be pulled tightly before they can come out with a good sound. Practice the closure of the vocal folds on the practice of coughing, coughing is the vocal folds closed and washed open a process, coughing before the preparatory action is the action of the vocal folds closed, and you will feel the abdomen with the force, this force is singing needs of the power of the Dantian, that point of gravity is the pivot point. False voice is that you usually learn the sound of girls talking, this need not be said, but you can usually practice the conversion of false voice, that is, you first false voice out of a sound, it dragged long into the real voice, out of the false voice of the vocal folds are not closed, you try to close the vocal folds after the can be converted into a real voice, this needs to be practiced, may be a failure at the beginning of the more practice will be good. Singing is all about control, control of the vocal cords, control of the voice, control of the breath, and control of the emotions. It is best to find a teacher, uneducated is not very realistic.
