Watch the Intro to Soloing online guitar lesson by TrueFire from Play Country Guitar 2: Rhythm & Lead Fundamental

Soloing is a big subject, but it starts with some simple examination of techniques that are available to you to use. Learning each of the various techniques that can be used in soloing, and then working on them individually, will eventually lead to you being able to string them together as you play a solo. That is what makes a great solo, being able to flow from one technique to another while utilizing scales and licks to express yourself.
