aaaaahahahah as i was reading the article, i was thinking about posting the bridge to 'how blue can you get?' but i see i done been beat to da punch.
i gotta disagree with the definitive recorded version tho. it's on 'bb king: live at the regal' where it serves as the climax of a medley of four of bb's greatest works, starting with 'everyday i have the blues' then jumps to 'sweet lil angel' and while preachin to the crowd (the regal was chicago's answer to the apollo ) bout how not everyone is an angel allla time, he seques into 'it's my own fault' . very few live recordings manage to convey the synergy between performer and audience the way it was captured that night with these 4 tunes (even tho that's always the intention). by the time he gets to 'how blue can you get?', he's become pure magic. as he begins callin out 'i gave you a brand new ford...' it's almost scary...and so powerful. as he delivers the line bout givin that woman 7 children, the whole place is up for grabs. they really shoulda tore down the regal the next day if for no other reason than it coulda never survived another one of those.
anyone who knows where to position his left hand on the neck to most effectively (efficiently too) locate the component tones of the kinda jazzy progressions bb's been using for years AND who has the talent to exploit those tones individually or 2 or 3 atta time, knows as much as he needs to know about chords.
he may not be able to create horn charts easily but i'm bettin he could do it. my guess is most of the guys who learn to play blues in the rural south may not be able to tell you how a 7th differs from a 9th or even the names of chords they play (especially if they use an unorthodox tuning like albert collins for example or even just an open tuning ) but they know what sounds need to be combined and where to find those sounds.
