DISSONANCE AND CONSONANCE 85 



1. Original harmony is harmony in one voice and 

 the harmonic basis of music. 



2. The original dissonance and consonance had 

 their genesis in one voice, and their component tones 

 are the seven original tones here identified as the seven 

 diatonics of the Major mode. 



3. Harmony in one voice asserts itself; each indi- 

 vidual tone reports itself as root or third or fifth or 

 seventh or ninth, and these reports are common and 

 unalterable. 



4. Rhythmic groups of tones generate and assert 

 their relation to a particular subharmony ; now it is one 

 regnant harmony, now it changes to another regnant 

 harmony. In one-voice music the regnant harmonies 

 arise by natural selection, in multi-voice music they 

 are due to personal selection. Regnant harmony de- 

 termines the exact relation of each tone in a melody. 



5. From the original dissonance and consonance 

 are derived three fundamental forms of harmony, 

 namely, the three-tone, four-tone and five-tone forms ; 

 five original harmonic percepts, namely, 1, 3, 5, ?, 9. 



6. The mode-idea had its origin in the basic rela- 

 tion of cadence and repose,m which relation the original 

 dissonance and consonance had their origin. From 

 the first the mode has been harmonic and is based on 

 the two harmonic genera of tones. The tones of the 

 two genera being the seven Major diatonics it follows 

 that the Major mode is the original mode. 



7. Melody is the composite vehicle which has intro- 

 duced one by one all these tones, percepts, forms and 

 regnant harmonies of the Major mode.
