so ever since i discovered that i shud draw air into my diaphragm not chest, my singing voice sounds different- deeper and maybe a little huskier... firstly, should this happen? now that ive been singing like that for a good 4 months and practicig ALOT, it seems hard for me to sing in a clear/lighter tone anymore... my friend recently told me im making an "artificial" voice... see now im confused.. then wuts my "normal" voice? im just confused... is my voice supposed to be lighter or something?

I suppose you have a teacher, who told how to use your diaphragm. If you are a male, most probably you have already been using more abdominal breathing than chest. It is normally the opposite for female beginner singers

Singing is not so much different than normal breathing and speaking. But you must use your diaphragm to sustain the air pressure and also to increase the quantity of air vailable for the emission of sound. If you chest-breath, you would be running out of air in moderately long phrases. There are other problems with chest breathing, particularly if you sing lyric music with "imposted" voice.

But I do not think there is a direct relationship between the low abdominal breathing and the clarity of the voice. IMO ther must be some other reason, probably related to the different muscle tone of your chest and throat. Try relaxing those parts, including the neck muscles.

If you have a (good) teacher, you should ask for his/her advise.
