@dannyg120 One way to think of it is that the blues scale is like playing many notes of the minor 7th chord (e.g. Cm7 chord notes = C Eb G Bb and adding it's b5 (Gb) -- over the sound of the major chord (C E G ). The Eb and F# (or Gb) both sound dissonant against the E natural and G natural of the C major chord, which is what makes it bluesy. Pretty cool!
Not very many people notice this either, but a C blues scale contains notes from a G# diatonic scale (with an added seventh). If we leave out the 4th of the C blues scale (because F is the only Utonal note in a G# scale), we can represent this scale in just intonation. This representation would be 10:12:14:15:18. The fourth would find itself somewhere inbetween the 12th and 14th harmonics (a quartertone sharper than the 13th harmonic).
So all blues scales are rooted in the minor of the key huh?

@tomatoe0000 Whoah! This makes my brain spin around. I'll tinker with your ideas and see how they play out. Thank you for the suggestion!

also sounds like a minor played over a major with a b5.
