Leaving aside reading music which I never really learned,
Interestingly, the only accurate
way to notate guitar music is with TAB. Going off a normal staff arrangement doesn't tell you which
A, for example, you should be playing. Is it at the 17th fret of the E-string, the 12th fret on the A-string, the seventh fret on the D-string or the second fret on the G? Although technically
the "same" note (at least on a staff), they each have a noticeably different timbral quality, a slightly different response time, and a significantly different sustain-decay ratio. That's due to the difference in string sounding-length, gauge, tension, and construction (i.e. wound vs unwound).
That difference is something that's routinely used to good artistic effect by masters of the guitar. It's not just what
notes you play, it's also
where and on what strings
that makes a difference. Bass players too, where the differences between neck position and string being used are very
audible. Even to an untrained ear.
Then there's how
you play a chord...
As with single notes, there are many different patterns to get the same chord. But some work better than others because of the specific inversion
found in the triad; or because of which notes
happen to be doubled in the chord, and where and on what strings it's played. That is what makes the biggest audible difference in sound between the "exact same" guitar chords. And to get an accurate chord transcription you also can’t
use traditional music notation. You need the actual chord diagrams
to duplicate what the guitarist is playing.
TAB and chord diagrams...their use is often mocked by "classically trained" musicians. But the simple truth is: they're the only
closest to accurate
way to notate guitar music.
