YES!!!
I played for about 6 months on my own. I could play all the basic major/minor chords & a few barre chords. But had no clue how do play anything else, I knew an A chord was a A chord, but did not know WHY it is a A. I learned about the fretboard & the notes on it plus load of other stuff.
BUT MOST IMPORTANT!! Im learning the CORRECT way to play.
