Hi Mark

I am not sure if you have checked out the Fundamentals courses, but if not it is a great place to start. Lisa goes over basic foundations like scales.

When you hear you favorite lead guitarist they are essentially playing scales. Its a bit more complicated than that, but there are a lot of big names that have made a living off the pentatonic scale(s).

Making music out of those scales takes creativity, technique and practice. Otherwise you end up doing scales and nobody wants to listen to scale practice.

So to answer your question directly, if that is your only interest right now, do a search for "lead guitar". It is going to bring up all sorts of lessons. However, I think you are cheating yourself if you don't give Fundamentals a good shot before hand. It really does give you a good foundation of "why" things work together.

Whatever you decide, good luck.
