Watch the Bird Song online guitar lesson by Jeff McErlain from Essentials: Chord Tone Soloing
Here's a really fun chord progression based off of the Leon Russell tune "Hummingbird". BB King also recorded it, and John Mayer did as well. It's a great tune as it's not quite the blues, but certainly bluesy, and this will allow me to dig a little deeper into chord tone soloing as one scale doesn't really fit all in this case.
Actually, as we move through this course, we'll see that thinking just scales doesn't really do a progression justice. If we look at the melody of a song, I can bet you it's primarily chord tone based. It's very difficult to sing a note over a chord that's not a chord tone.
