This reference for C major divided into five positions serves multiple purposes. First, it provides a framework for internalizing how the guitar neck is organized into positions across the fingerboard. Once you become familiar with these positions, you’ll be able to transpose them not only into all major keys but also into minor keys and modes.
Second, this approach helps reinforce your understanding of the notes on the fingerboard. By learning the locations of the natural notes within these five positions, you’ll be able to identify and apply the remaining sharps and flats across the fretboard.
