Hmm heres an idea.
Do you think when in a band and your jamming in the key of C perhaps, when it comes to solos is it ok to have the scales in front of you? I mean i was just wondering is that what guitar players do, look up a scale and try it out or do they know all the scales!! because i thought that would be a cool way to learn!! i sit with the, for example, C major, and C pentatonic and jam on them, move from one to the other and stuff, but i probably wouldnt be able to do it as well without the stuff in front of me. Also, do you think guitar players know the names of scales? slash uses the C ionian in nightrain, do you think he learnt it as that name or as a scale he discovered on a record too. I only knew it as a the scale thingy from nightrain until recently!!
