1) Is there any other progression in the blues apart from the 1 4 5 one and what kind of chord would it be, a dom7 still? For instance, if i were playing strictly in the major scale i could add the VI before going back to I ( I IV VI V), well something of that nature. I cant do this when playing blues cuz the VI just sounds like crap. BTW this is for piano but the music theory still applies.
2) What other kinds of chords apart from the dom7ths have a bluesy sound to them?
