The Blues Scale is actually a 6-note scale that is essentially a modified Minor Pentatonic Scale with an additional “blue” Take note, typically the ♭5. The scale isn't going to comply with a traditional pattern of full and fifty percent methods like other scales. (very same Take note as b13th). https://playcsharpdorianonaltosax05049.qowap.com/86014483/play-c-sharp-dorian-on-alto-saxophone-things-to-know-before-you-buy
