I found it really hard coming up with a title for this, let me explain! Apologies if this has all been discussed many times before. I was wondering how much our guitar heroes knew about what they were doing? I guess I mean music theory really. I know many guitarists don't read music, but I wonder how many of them understand theory of whether they just developed a feel for what they were doing? Did Hendrix consciously think to play a major based lick and then throw in a minor pentatonic part for a different flavour or was it all done by instinct? I think like many of us I learned the pentatonic 'blues' scale pretty early on, and then recognised that in the vast majority of Hendrix / SRV / Clapton etc playing, and so didn't look much beyond it. Recently I've been watching a lot of Justins Guitar tutorials on Youtube and learning some new approaches which I now realise was evident in Hendrix / SRV / Clapton playing all along. So, do those guys and other understand all the theory stuff or did they go by feel alone? I'm certain guys like Joe Bonamassa understand it all but I wonder if that's why his playing can be interpreted as a little clinical?
