So, I'm really trying to expand my theory knowledge lately and while I'm quiet familiar with major scale harmony theory I'm still far from being able to execute that knowledge on the guitar. I'm having a few books, Jazz Theory, introduction to jazz guitar soloing, the advancing guitarist, but wasn't really satisfied with the method of any of them regarding getting to know the fingerboard (I'll explain) and the use of modes. You see, on each of these books, they never talk about how you should practice modes on guitar and how should you approach them - as far as I'm concerned I'd play E major over A major 7th and follow my ear for note choice if I wanted a lydian sound and of course notes from the A Major 7th arpeggio. But then there's that issue of avoid notes and according to Jazz Theory for example you should learn all the modes in every key and eternalize them. Now that seems applicable to me if I was a pianist like the dude who wrote that book is, but how should a guitarist apply to know playing all the modes, in all the keys, over the whole fretboard? With that amount of work and information to memorize the chances of getting into the melodic minor scale harmony are quiet tiny. I'm not trying to cut corners here or get into shortcuts, I'm trying to realize what's the right way to study and what should I study, this whole thought of now memorizing the major scale shapes only with 6 more different numbering systems for the notes sounds to me insane instead of just using the major scale the mode belongs to and just use my ear. Can someone please be specific and explain how he applies this task?
