222 THE NATURE OF MUSIC 



consonance, that based on la being the original; the 

 minor form of dissonance, that based on mi being the 

 original. 



47. Harmonic Percepts of Minor Origin 



The minor forms of consonance and dissonance 

 comprise five harmonic percepts which correspond to 

 the five major percepts derived from the major forms 

 of consonance and dissonance. Both groups are 

 given below for comparison, and each harmonic per- 

 cept is indicated over the tone on which melody first 

 generated and reported it.

1. Percepts in Major: do mi sol fa la 



2. Percepts in Minor: I la do mi re fa

Among these percepts we observe one duplicate, 

 the small seventh, which originated in major on fa 

 and which was reproduced in minor on re. Thus 

 only four of these percepts had their origin in minor 

 and are therefore distinctively minor harmonic per- 

 cepts. They are : —

The whole number of harmonic percepts thus far 

 generated by melody and explained is nine, as follows : 



1, i; 3, 3; 5, 5; 7; 9, 9.
