When Rue & I went to see Griff & Laura on Sat. night....
(which is another thing - it shows you don't have to wait until you are at the top of the ladder before you can actually perform or do songs etc)
LP
LP you bring up such a great point.
When I started playing in bands at 15, I didn't know what I was doing either. I always say that I feel bad for my students over those first 3 or 4 years because learned much more than I taught from the experience
Obviously you have to be able to get through a song from start to finish, but that's about it! From there experience will be a better teacher than anyone else could be because it will show you (in no uncertain terms I might add) exactly where you are weak and what you need to improve upon.
From there, your teacher can fill in those gaps, but leave it to experience to light the way for you.
You might also enjoy knowing that when I started singing I was HORRIBLE. I could not carry a tune in a bucket. But I was in a band and we couldn't find a singer so I said I'd do it.
I took lessons, I practiced, but mostly I did a ton of gigs and learned where my voice sits and what it can do. I took those tips from the gigs and worked with a teacher to emphasize my strengths and hopefully bring the weaknesses to a point where they were not detrimental to the sound as a whole.
The process took several years. And while I'm not the greatest singer ever, by any means, I get more compliments on my vocals now than on my guitar playing. I realize that is because it is what more people notice, but it's still nice to hear.
So go out there and do it if you have the means!
