Non Full Sound

Hey. My voice does not sound pleasing to me in it's normal state. İ think it either sounds too unclear, nasaly or just not round full and sharp. Especially my headvoice and my overall voice. Can someone help me to pinpoint my problem and fix it because i feel like it is the only thing holding me back. İ can sing clearer but that i feel like hurts my throat and for it have to but tension on my throat and breathe out as little air as possible while singing and i think it is harmful for me to sing like that but it sounds more full and round then.

Hi, Ahmet! I'm pasting your other (similar) question here so it's on one thread:

Hey I wanted to ask how I can develop a fuller voice as I feel like that's my only big problem right now. When I sing in chest voice my voice is not full but when I go higher in pitch my voice becomes fuller. 

It sounds like your main issue is tone. I recommend watching this live lesson I gave on improving your tone! Here's a tutorial on tone as well! Below are a few tips.

Two ways to approach modifying your tone: 

(1) Change registration (chest/mix/head) + use specific physical adjustments (dropped jaw, lifted palate, height of larynx, etc).

(2) Using your ear with good tonal models: find singers whose tone you want to emulate, and use your ear to imitate them (as best as you can). Recording yourself + playing back is a good way to see how close you're getting! Doing "impressions" can teach you how to make tonal adjustments with your ear (and brain). Physical adjustments will result (ie: you try to sound like Kermit to Frog, and if you're successful, it doesn't just magically happen: you're constricting your throat in some way, but to get there, the specific sound of Kermit's voice was the goal, not the throat constriction). 

Thank you :)

Hey so I think that this is not my main problem. It's pretty hard to explain explain what I mean that I think that my problem is. Is there some way I can do a voice memo to explain what I mean ?

You're welcome, Ahmet!
