Hello guys. Let´s put as example All of me.
First Bars / C / C / E7 / E7 / A7 / A7 / Dm7 / Dm7 /
Over that E7, I was taught to play E7 Mixolidian, since it goes to a major chord. But everybody seems to agree in playing E7b9b13. How is that? Is it because the chord is on weak bars? One teacher told me that. Next time an E7 appears is on strong bars going to a minor chord. I´m not sure if the harmonic rhythm is so important in this case.
I learnt that Mixob9b13 is for dominant chords going to minor chords. Particulary VIm or IIIm chords. Over V7/II would be the Mixob13.
