112 THE NATURE OF MUSIC 



reports a harmonic form and relation. 2. Every 

 tone reports a consonance or a dissonance, is in 

 cadence or repose, is a by tone or a regnant tone. 

 3. Every step from tone to tone, from harmony to 

 harmony, is a progression or a resolution. 4. All 

 these reports are common reports. 



10. The regnant harmony of the moment is the 

 repose and equilibrium of that moment. Whether the 

 regnant harmony of the moment be I or V or IV or 

 any other it is the repose and equilibrium of that 

 moment. This is illustrated in our last example 

 where the regnant harmonies appear in this order, 

 I — V — I — IV — I — V — ^I. Here we note the wider 

 application of the term repose in the sense of the 

 equilibrium of the moment. 



1 1 . The regnant harmony of one moment relates to 

 the regnant harmony of the next moment. But the 

 relation of a byharmony is confined to the single 

 moment of one regnant harmony. See last example 

 but one. The basic rhythmic links of a melody are 

 its series of efficient accents, and the basic harmonic 

 links of a melody are its series of regnant harmonies. 

 Since the tones that fall on efficient accents generate 

 and report the regnant harmonies, and since the 

 moment from one such accent to another is that of 

 one regnant harmony to another, it is clear that these 

 rhythmic and harmonic links of melody are insepara- 

 bly united and interdependent. The minute analysis 

 of this relation of and movement from one regnant 

 harmony to another now confronts us. 



12. The steps from I to V and I to IV are 

 progressions; see below at a) and c). The steps
