Watch the Performance Studies online guitar lesson by TrueFire from Play Country Guitar 10: Advanced Soloing Approaches
In this second section, you'll play your way through and dissect a ton of great country solos. You will not only learn some important techniques as you play these, but you will also be building your own repertoire of cool licks, moves and ideas.
TIP! The key to having great soloing and improvisation chops is continuing to build on your basic soloing foundation. So you should be working on things like targeting notes, making sure you are playing the best possible note you can. This requires you to be knowledgeable about what the chords are doing underneath your solo. That is one of the things beginning soloists don't do enough of is pay attention to the chord progression they are playing over. You also have to keep your technique sharp - it is not good knowing all the right notes to play if you are sloppy and can't get to them in time. So while you have to work on the knowledge side of music to really advance your improv, you still have to be spending some time working with a metronome and pushing your physical limits as well.
