Now a quick question for you. If you listen to the soloists you played using the blue scale, and the solos you've played in this section has any thought popped into your head. It wouldn't surprise me if you thought that the blues solos that you played using the blues scale, sounds bluesier and a bit cooler. The reason for that is that the blue scale will let you play a lot of notes that create tension towards the chords. Whereas when you play only using chord tones, you don't create much tension at all, with the exception for the flat seven. In the next section, we take a look at how we can create tension and then releasing that tension at the same time as we take advantage of the core tones.
