116 THE NATURE OF MUSIC 



Here we observe that regnant IV, though it is 

 a consonance, is in cadence to I. Hence this truth : 

 Consonances as well as dissonances may be in cadence. 

 Further analysis will extricate us from what here 

 threatens to become a tangle of terms. This may be 

 avoided by at once stating the following general truth 

 which opens up and covers the whole subject of 

 regnant harmony and its byharmony. Both byhar- 

 monies and regnant harmonies may be either conso^ 

 nances or dissonances : the former are always in cadence 

 or unstable equilibrium, the latter may be either in 

 repose (stable equilibrium) or in cadence (unstable 

 equilibrium). Byharmony and dissonance, regnant 

 harmony and consonance, these are not interchange- 

 able terms. Confusion of these terms will result in 

 complete confusion. Distinction between these terms 

 will preserve complete clarity. 



13. In the harmonic analysis of melody the series 

 of questions to be answered are these: 1. What is 

 the regnant harmony of the moment ? Is its form a 

 consonance or a dissonance ? What are the regnant 

 tones and their relations ? 2. What are the bytones, 

 their relations, the forms of harmony they represent ? 

 These leading analytical questions apply to all music 

 since music the world over, past and present, primitive 

 and modern, one-voice and multi-voice, is one in kind. 

 These questions therefore apply to bird-melodies as 

 well as human melodies, to oriental as well as occi- 

 dental music, to Greek and Ecclesiastical melodies 

 as well as to folksongs and dances, sonatas and 

 symphonies.
