hi kajima,
i first of all learned to play the guitar so people wouldnt hear me singing, at 14 i couldnt sing two notes in the same key. but i wanted to sing, i think i've improved over the years a bit, and i do between 3 to 4 hours when i do my gigs. i only do a couple a week so no big damage done. i did my first solo gig the day after elvis died, before that i played with bands.
technique is very important to me, and i listen to how proffessionals sing...not the likes of kylie minogue, real singers like lennon, mccartney, tom jones, etc.
it is true...anyone can sing, but it takes work and dedication. in the time i've been on the road, i've seen so many karaoke singers come and go, they get all their mates egging them on, so they spend thousands on equipment, just to sell it all cheap a few months later. it's a hard way to live, and harder to keep it up for 36 years like me.
as other moderators have said above, you can enter a song you have written in the songwriters section or the poetry section and ask for help with recording. if you go to the recording section, russel harding has a thread there for names for helping with recording, put your name down for vocals if you like. but the best start would be to write and record your own song, submit it, it wont matter if it's not quite wonderful, ask for help and you'll have plenty of offers.
hope i've helped you
