not diatonic harmony but blues based harmony discussion

[Clifford-D]

Ok this topic has been floating around the thread lately

Take the tune 'Back in Black'
E5 D5 A5

This song is not based on diatonic harmony

It's based on Blues harmony theories

please tell me all you know about blues based harmony.

And how it's used in different styles of music.

How it differs from diatonic thinking

And I will be happy :NUTS
