any scale begins at a root note called the tonic from which the intervals are used to construct whichever form of scale you want to construct most common being the major and minor scales with each having it,s own tonic or root note and set of intervals starting at that note.This is only the scale being used and not where one begins to use it on the music staff.The c major scale if being written out would obviously go from c to c an octave higher but in its musical use would not necessarily start at c and end at c.Obviously one cannot practically play a guitar or any other instrument all the time and when not playing it is good to work on music theory in relation to a keyboard or piano as i find tabs are a sort of inbetween concept of relating a guitar to a not much easier way of reading music if you learn proper music theory you,ll be able to relate to any instrument.Having done so myself i find it a great assett and not at all difficult to learn but one really has to learn relating to a piano or keyboard to grasp it fully.Then the knowledge gained will only add to your music theory understanding.The internet is a goldmine of knowledge on music theory and much of it for free so spend some of that time when not actually playing learning scales,intervals,chords,inversions,progressions,circle of 5ths/4ths and much more.
