I've recently been told that my every-day singing voice is in my head voice, therefore, I sing in my head voice all of the time.
Now, I'm fairly sure this is a bad thing, it doesn't give you the right support or such things I've heard. Problem is...I can't find my chest voice.
Is your chest voice feel the same as talking, just in singing form?
And why is it so impossible to hit notes when you sing like that?

Please, please help. The person who I can ask is crazy so, I'm looking to this. xD.

I would not worry too much about this terminology, it is quite confusing and is being abandoned by most.
Have a look here:http://en.wikipedia.org/wiki/Head_voice

If head voice could be considered to be the "falsetto" and it happens you sing normally in that way, it could be good for you (if you are male), as male altos and sopranists are very demanded.

I would say that chest voice is the lowest part of your register, and this is the reason that hitting the higher notes is not possible there. But coming to what notes you can hit normally without going into falsetto, it depends whether you can be considered a bass, a baritone or a tenor (for males) and alto or soprano for female and also much on your singing technique.

Chest voice, is when you use your lungs and diaphragm to sing. Head voice is the usage of solely your larynx. Of course you must use air to produce sound, but the chords are much more pulled together, making the pitch you produce higher. Similar to The Temptations and a lot of metal singers use a head voice or a falsetto to hit high notes, which is only natural for most males.

You should feel your chest vibrate when you talk. You should also feel your chest vibrate when you sing, naturally. When you use a head voice, whistle, falsetto or whatever you want to call it, you do not. That's because the sounds is not refined and produced in the bottom of the lungs, where your diaphragm (your singing muscle) is connected.

You may also not be singing loud enough. But be aware, you should utilize both techniques, because they add different soul and flare to your performance.

Practice imitating this guy, for he uses the correct technique of singing and his voice is very low and certainly impossible to imitate in a head voice:

"I would say that chest voice is the lowest part of your register, and this is the reason that hitting the higher notes is not possible there."

Although your chest voice IS the lowest part of an individual's register, it's still very possible, and natural to penetrate the upper register in a chest voice, although extremely difficult--not something that can be learned. Ever heard of Queensryche?

Geoff Tate. That is all.

Head voice is not falsetto. Head voice is upper resonance, which sits in your upper head, starting from upper teeth and it has nothing to do with larynx. Chest voice is lower resonance. Chest voice basically makes up the keynote what you are singing and head voice enriches the sound with harmonic tones. It also(head voice) helps to relax your larynx from tensions(if used properly) and gives extra support and endurance, especially in higher register. It's a tool to help the sound you are producing to reach far in big concerthalls/churhes, without using mic and unnecesserily large amount of energy. However, it's important to reach balance between head and chest voice.

This may not have any meaning for you, if you haven't engaged yourself with classical singing and opera.

Good luck
