The Guitar Fundamentals courses cover location of notes on the fretboard & the basics of music theory, intervals, scales, chords, reading music.

The circle of fifths is slightly beyond the beginner level in which we are just trying to get you to build some playing skills & corresponding concepts!

However, once you are ready for it I have plenty of tutorials that cover more advanced music theory topics. Like these on harmonizing scales.
