262 THE NATURE OF MUSIC 



Crete as regnant harmonies the self-reports of which 

 are perfectly distinct. The distinctive peculiarity of 

 these compounds is simply this : The added tone does 

 not disturb the identity and "predominance of the triad. 

 Conversely, the triad preserves its identity, regnancy 

 and predominance after the tone is added. For ex- 

 ample : after superadding A to the C-major tonic-triad 

 the triad still retains its identity, regnancy and pre- 

 dominance and we hear the new combination as the 

 major tonic-triad plus the added tone. True, the 

 resultant chord is a new and distinct idea and unity, 

 and the added tone adds something new to the self- 

 reports of the triad-components, thus creating the 

 compound chord, nevertheless the truth of our thesis 

 persists, the triad does not lose its identity and pre- 

 dominance. The nucleus-triad of a supersixth or sub- 

 second chord may be major or minor or augmented 

 or diminished, and every type of these chords may be 

 found on any tone in any key. This conveys some 

 idea of their limitless number. Below in parallel ex- 

 amples are supersixth-chords based on the triads of 

 the major and minor tonics, dominants and subdomi- 

 nants in a), h) and c) respectively. These chords 

 are marked by adding the symbols +6 to the bass- 

 number, pitch-modifying signs being added when 

 necessary.
