I have been practicing my 5 positions for the major scale, more specifcally the G major scale. Each position is the two octave scale, now I see three note per string scales. I know they are the same notes i.e. G major. What is the advantage of some three note per string scales? How important is it to know the letter names of each note of a scale? I can randomly improvise with the pentatonics until I hear the right notes when playing along in a progression. Which brings me to another question. How do you use your scales?

Is there a correct way to use a major or minor scale, for example would you want to record a progression that is diatonic to the scale being used and improvise that exact scale to create a melody. I use some backing tracks and play in that key.

I don't mean purposely to sound fragmented in my thoughts but if one question was used, how and what is the right way to practice and use scales? Thank you for your thoughts on this subject.
