Hey guys, for whatever reason, guitar scales seem to be one of those things I can't quite wrap my head around, and I feel like being unsure of myself about the "rules" of where I should be playing in a certain section are really holding me back as a guitar player. I have guitar pro 6, which I love because I can punch in a few notes and it will tell me what scale those notes are in and I can just follow that scale, but it doesn't seem to always work right. For instance, on my band's cd I'm trying to come up with a melodic lead for a section, and it's tuned to Drop C. I download the guitar pro file for Killswitch Engage's Breathe Life (also in Drop C) to see what scale that solo was in. I highlighted notes from Adam's solo and it came up with no 100% match. A few other tabs have the same problem. They sound correct as far as whoever tabbed them out goes.I know this is getting long-winded but my question is , how do you guys usually go about figuring out what scale to follow? Some guitarists have told me they just play whatever sounds right, but what about if I want to harmonize it? Having the scale in front of me makes that so much easier. So can anyone explain what I should do in basic terms that I can understand? Thanks in advance for any help!
