THE NATURE OF MUSIC 



Further illustrations of diatonic bytones will appear 

 in the chapter on cadences. 



16. The truth that a tone's specific harmonic 

 form is caused by its specific combined relation in 

 time and space has been and will continue to be 

 demonstrated. Thus far each of the seven diatonics 

 (original tones) ifas appeared as a regnant tone and 

 as a bytone, and has reported one of the five original 

 harmonic percepts 1 or 3 or 5 or 7 or 9. Thus far 

 each of the seven has appeared in the following 

 harmonic relations: do as 1 of I and as 5 of IV; mi 

 as 3 of I; sol as 5 of I and as 1 of V; ti as 3 of V; 

 re as 5 of V; fa as 7 of V and 1 of IV; la as 9 of V and 

 3 of IV. This summary shows that four diatonics 

 (do, sol, fa and la) have appeared each in two har- 

 monies, while the remaining three (mi, re, ti) have 

 appeared only in one harmony. The former are 

 bond-tones or connecting links between two har- 

 monies. Of these sol is the first and the nexus 

 between I and V, I and V,, I and V9 as follows: —

The next bond-tone is do, the nexus between I 



and IV.

Sol, being the original bond-tone and first connect- 

 ing link between two harmonies, was the first of the
