The blues scale is a minor pentatonic scale with one extra note. We're gonna play it in the key of E. We'll find E on the 7th fret of our A string, G on the 5th fret of the D string. Now, A, now, B-flat, that's the added note. B, D, on the 7th of the G string, and then E on the 9th fret. The scale itself sounds like this. So, when we're using this blues scales, we want it to sound natural, we want it to sound off the cuff, and we want it to sound spontaneous. You don't want the blues scale to sound like a scale. It comes from a vocal gesture, so you want it to sound like you're singing, sound like you're singing the blues. So, we want to think about it like a spice, an ingredient, something that we can use to color the music, and not something that we depend on, like a scale, to just run up and down it in a boring way.
