Agh studio singing gotta love it!
I'm in the process of finishing off my first album with vocals and its been fun!
I think my voice is ok, I have my own style and it suits what i write however i'm not a natural by any means. Although that doens't mean you cant get pretty close with practise
And thats the biggest thing really, practising. Think about how many hours you put into guitar playing? If its anyhting like me its about the same as the average 8 year now practises video games! So you really need to work your throat. And practise with a purpose also. Really concentrate hitting your pitches.
Learning to control your "different" voices helps. I find that I can sing more chesty and resonant at deeper pitches, and then as I get to a certain range it changes to a more throat defined timbre. It helps to be able to effortlessly blend these. This is in addition to head voice or falsetto. Your girly voice in other words.
I also find that breathing helps. Sounds silly but its so true. The deeper and more controlled you breathe when approaching your lines the more power and control you have over your pitches and tone.
In regards to recording your voice....
Do it line by line if you need it. The pro's do. even singer we all know and love certainly dont do 1 take wonders in the studio. Its pieced together. And on that note. Try recording 3 or 4 takes all the way through, then you can piece together the best bits from each.
After that if you stil dont have the right bits in some places go in for punch ins from there.
Hearing yourself in the headphones is a strange one. I personally dont like to hear myself in the cans. Just the track. For some reason i pitch better like that trusting the vibrations of my chest rather than getting put off by my actual voice!
But some people like to hear it, and a lot of girls i recorded love to have copius amounts of "talent booster" in the cans as well (known as reverb to some people).
I've found that a good mic pre-amp and compressor is ESSENTIAL for getting a great vocal recording too. I'd definatley recommend a vocal chanel strip or something, that is a pre/comp/eq in one rack space. (i use a focusrite). I mean I cant stress the INCREDIBLE differnce recording with a sensible amount of compression gives you. It also makes your performance more confident because when you go high you dont have to crank you neck away from the mic just to level the volume out.
Obviously the pre-amp also gets the best tone out of the mic. And while we're taling of mics a large diaphram condensor is essential for all applications bar bands that have self called "screamers" - not singers. In that case get the sm58 out
I dont eq while i track vox, but sometimes depending on who you're recording you might need to. Again a vocal chanel strip is a lifesaver.Hope this helps
