The 1, 3, 5, interval order chord construction exercise for the most part requires really splaying your fingers across the fret board. When doing these chord construction exercises and starting on the E string, the B string and it’s different tuning is ignored thus the architecture is more purely just the circle of 4ths. Overall this exercise helps the user understand the modes and how each of the 7 different tones has a different feel especially when played as a chord. It also helps the user develop muscle memory and other skills that can be efficiently deployed toward playing guitar. This exercise when combined with the Arpeggio exercises is great to helping users really understand what modes are and basic skills toward creating nice rhythmic melodies and intricate harmonies. Having the straight fourths tuning architecture by avoiding the B string, helps the user really understand how to construct a 1, 3, 5 if they are to use contiguous strings.
