Watch the Get Ready for Change online guitar lesson by Jeff McErlain from Soloing the Changes
I stated earlier that this is the way to practice playing over chord changes. Find a note that you want to incorporate and hit at the proper time. When practicing soloing over the chord progression, make sure you overuse that note. By overuse, I mean hit it every single time, so it sinks in both in your hands and in your ears.
For some reason, I thought these things would come naturally at a point in my guitar playing. When you think about it, that's just plain old stupid. How could I expect to make chord changes and understand the inner workings if I didn't practice them? So now, no matter how simple the chord progression, I will still take time to practice over something I intend to play on in a live situation or a recording. I am continually amazed at how often I pick up something new to do. Even preparing this course I learned in number of new things or refreshed many things I used in know. Remember, you can't expect anything to happen unless you practice, and you need to practice smart. What worked for me is choosing one note at a time to add into the solo that outlines one specific chord. Then move onto the next. That's what works.
