Theory

[mountain man]

So we can play:
I pent minor over the I, IV and V
I pent Maj over the I, I pent minor over IV and V
I pent or diatonic Maj over the I and the IV pent minor over the IV and the V pent minor over the V
And then you can use the I pent minor over the I , IV pent minor over the IV, V pent minor over the V.

Blues chords can have the dominant 7th for the I, IV and V which is diatonic. yes?

Why can't we play the diatonic IV and the diatonic V over the IV and V?

What are the diatonic interval tones that cannot be played over the IV and V and why? Is there anyway we can play the diatonic but be careful on certain measures to avoid certain interval tones?

I hope you understand the theory question I'm asking.

Please discuss any variations that also go along with this theme.

Hasn't Griff said that in a blues you can treat every chord as a I chord

isnt that like a participation trophy........you all get to be a number 1 chord, yeaaaaaahhh

but yes, I do believe he said that, and I do chord chasing all the time, since I am not a great lead player, it works for me

This works as long as you stay with the pentatonic scale. Even still you have the pent Maj and the pent minor which makes a difference on the IV and the V. Then when you add the diatonic scale things change.

Someone might point out that the I, IV & V in a Major Key would be diatonic. For example, A, D & E.

Dom7 chords in a blues, such as A7, D7 & E7, are each the V7 chord of a different key. i.e. they are not diatonic.

(They are the V7 in D, the V7 in G and the V7 in A, respectively.)

Playing over the Dom7 chords in a blues is a whole different animal from playing over the 3 Major chords within a key.
