LeahY I have been enjoying your Stride Blues course. When I learned about blues boxes for guitar I was trying to figure out how to apply that same concept to the keyboard. When Alfie went over thinking of blues scales as little segmented clusters of keys instead of a full scale it was a real ah ha moment for me when I related how that concept is sort of like a blues box can be applied on guitar making the blues scale more practical and digestible.
