62. The role of the relative pitch order of the roots of two chords (position) versus the role of their invesrion voicing


If we define as voicing of a chord as the particular combination, or inversion type of the chord together with possible repetitions of notes (especially in the open chords that have 6 notes, instead of 3 or 4), then the position of a chord is defined by the specification of  what octave  the root of the cord is found and for the guitar fretboard what is its exact fretboard shape and position (see post 23 for a special symbolism for this). 

In particular , the relative positions of two chords e.g. V7-> I (in the roman numbering of a diatonic scale) or X7->X+1 in the symbolism of the wheel of 24 chords (see post 34), is also defined by which root is higher, that of X7 or X+1? Normally for such a dominant->root resolution it is usually intended that the root of X7 is lower that the root of X+1 but in the same octave.  The sound feeling of the succession of such two chords is entirely different if the root of X7 is higher than that of X+1 or vice versa. E.g. The G7->C in particular  G->C as open chords of the guitar have such position that the upper root of G (In the high E-string) is higher that the upper root of the Chord C (on the B-string). While for the D7->G, in particular  D->G , the upper root of D (on the B-string) ,is lower that the upper root of G (on the E-string). 
This distinction becomes even more important if there is parallel melody, which requires that the chord follows it, and that some of the notes of the melody are identical with some of the notes of the chords in  pitch too and not only in name. Then with such a requirement in the melody-chord relation, the melody itself defines if the root of X7 will be higher or lower that the root of X+1, which also may define the type of inversion , shape and position of the chord on the guitar fretboard. 
In the next we shall present some examples, and we shall discuss the role of the relative position of two chords of a chord progression on the guitar fretboard.
