Hi,

I've recently started playing more and recording some stuff. All of it is acoustic type stuff, but I'd like to try and record some simple lead stuff over the top too.

I've pretty much just tought myself, and just really understand how to put chords together that sound reasonably ok. But I don't really understand how playing some small lead part "works".

For example, say a simple song with the chords G, C, A, D. As far as I understand, I should play some variation of a scale over the chords, but I'm not sure where I should start. Do I have to play a scale in G, then move to a scale in C, then A then D as the chords change?

Hopefully someone can figure out what I'm trying to ask for, as I don't think I've made it very clear!

Thanks in advance to anyone who can help, or point me in the direction of somewhere I can read about it.

Thanks again...
