Okay so ive been singing for a few months now and love it. When i first warm up and try sing, it doesn't sound bad but its just overall breathy and there's no power. This has happen quite a lot and it gets really frustrating so i give up and just watch TV for like 20 minutes or so. When i try it again, suddenly my voice has opened and is more powerful and ever, i can hit all the right notes with power and control.
Why does this occur? Is it normal?
Also if i about to do a gig, does that mean i should warm up then wait THEN sing?? So confused.
Thanks for your time :)
