Hello Luciana,
I'm glad to be here, singing has always been a weakness on my end so it's a great opportunity for me to get started. Something I know I'm lousy at and I always thought there's no room for improvement. Let's see if there's any hope for me

About technique. A steady diaframe and let the sound form in the roomy space of your moutch/throat and not in the front end of your mouth. Something like that?
The only occacion where I have been singing was during a gig me and my friend had at "hot shot" bar in Chania, Creete/Greece. Me and my buddy on one guitar each and he was singing. All the backing on mini disk. Two weeks and I had one song to perform each night, "You're my heart, you're my soul" - Modern Talking. My friends demand since he wanted to rest his voice for one song. I didn't want to sing at all but I game him that. One song only, how bad could it get?
This was around 98-99 when they had their big revival and I sang it once and was requested to sing it 1-2 times more per evening.
Pulled it off though, wasn't comfortable about it though.
But all in all, I havn't sung a lot, on teh contrary it's something I try to avoid
I think singing would help me a lot in my music creativity. Perhaps I can also do backing vocals in our band.
My favourite music stretch from vintage rock, Led Zeppelin, old ZZ top, Deep Purple, Black Sabbath, most of the 80's hard rock and metal, Dream Theater, Sun Caged and other progressive stuff, some modern metal bands and rock bands aswell.
Plant is a great vocalist, John Fogerty, Neil Young. Ozzy has great character in his voice, one of a kind. And I'd gladly have Ronnie James Dio sing in my band. And Clapton for that matter. Add some more rock vocalists, not always the better schooled ones but rock n roll.
I don't have a wide registry, rather to sing i A or D and don't spin off too much from there. And quite muffled voice,not so clean and clear
Sorry to say I don't have anything recorded of my singing, and atm I have a cold and sore throat so I can't come up with anything today.
Anyway, looking forward to get started
