Quoting this because I'm in the middle of doing this with Satriani's "Summer Song," a solo I've tried and failed to play a couple times over the years but think I can probably pull off now. There's two specific points in the "main" solo where the official transcription I have seems accurate, but doesn't really tell the whole picture in that it seems like it's capturing what actually came off the guitar reasonably well, but also comparing it to live recordings and how the rest of the run was, how to say it, "functioning," I guess, it seems like the notes as notated were inadvertent. In two particular points, there's the pedalpoint lick off the G string where right before jumping a few octaves and pedaling off the high e 15th fret, there's some stuff around the 19th-21st frets where I'm pretty sure some of the slides and weird pull-offs were accidental, and then there's one extra pull off to the 15th fret coming after the wide-stretch 22-15 21-15 20-15 stuff where it pulls to the 15 before starting the next motif with the 18-20-118-15 stuff, which I'm reasonably sure was accidental - it doesn't fit in with the melodic or rhythmic pattern Satch was playing, and seems like it was probably just done accidentally while holding the 15th down but transitioning into the new lick. I'd been killing myself trying to get these accents excactly right in he middle of a lick that's already blisteringly fast, but I think if you accept the fact that this wasn't an intentional "lick" by Satriani so much as a byproduct of what he was playing, and play based on a reasonable interpretation of what he was trying to play, it becomes a (somewhat) more managable run. Idunno. Sure, use tabs... But use your ears and use your brain.
