Watch the Dominant Soloing 1: 20 online guitar lesson by Brad Carlton from Bluesology 1

Just when you thought you had enough to play with we throw a few more pitches into your arsenal. The 9th and 9 add flat 3 will be introduced in this lesson.
The extended form and condensed form of the arpeggios will be demonstrated. The extended form will articulate each chord tone in the following succession: 1-3-5-b7-9 spanning an octave and a second. The condensed form will fold these same pitches within an octave in the following way producing a six tone scale: 1-2-3-5-b7-9.
Employing the ninth into your solo will certainly add a very cool jazz sound to your playing.
Man, a lot of material to digest in this series. Savor it and let it digest slowly. What you learn here will be applicable to many other styles of music.
Play hard and have fun.
