1. Your throat area should be completely without tension. None. Whatsoever. That is, if you want to minimize your chances of hurting yourself and gaining a sore throat. Operatically, there should be no tension at all. With popular music (pop, r&b, rock, etc…) straining is more common, but even these singers can sing their songs well (and better) if they reduce tension.

2. Your range? Hm… Depends on what highest and lowest notes you can hit comfortably. Between them is your range. It’s advised that you have an instructor classify you as a bass, tenor, alto, or soprano. Bear in mind, instructors are not always right. Get second opinions. Then you’ll learn your specific "vocal fach," a phrase you’ll soon be familiar with if you ask around. An example of a vocal fach would be a mezzo-soprano, or a spinto tenor (me, I think. lol).

3. There are vocal registers. The chest register and the head register. Between them is an area where they overlap and mix. A human fact is that our chests vibrate when we sing low and our heads vibrate when we sing high. There are techniques you should abide by to control your tone as you rise and fall in pitch. Try researching passaggi (the plural of passaggio). It’s a sort of system that helps you to always sing without tension. But, no, that vibrating method you spoke of doesn’t…ring any bells for me. All vibrations in the body are natural. Some sites have weird information.

I wouldn’t say you’re singing too high as much as you may be pushing more than you need to. It will take practice to sing without straining yourself. At least, not as much. Straining can be stylistic, but it isn’t recommendable. There is quite a bit to learn about singing, but you are on the right path, my friend…acquaintance. Sorry for typing so much. Kick ass

I’ve been where you are. Been doing singing research for a whiiile (almost 2 years, maybe) and it’s payed off 10-fold. Never give up if you love it. Whether you think you can achieve it or not, you’re right.

This problem started occurring about a week or two ago. Every time I sing, the next morning my throat hurts and every time I drink or eat something I can feel little pains.

I read somewhere that your nose is supposed to vibrate when singing correctly and your chest isn’t supposed to do any vibrating. Well when I go low, my chest vibrates and when I go high, my nose vibrates. But I am afraid I am singing too high and causing my throat to hurt.

1. Is there supposed to be any tension at all in the throat when singing properly?
2. How can I tell I am in my range?
3. Is the vibrating method true? (Chest vs. Nose)

Thank you!

I’m 18…don’t know how that effects whether you could sing properly or not…
