THE NATURE OF MUSIC

 each of these triads. Of the many possible repre-

The triad V may be represented by the single com- 

 ponents re 5 and ti 3, the triad IV by the single 

 components la 3 and fa 1. Both triads V and IV 

 may appear in any of the above two-tone and three- 

 tone forms. 



From the prototype dissonances in one voice, V9 

 and Vy, are derived the corresponding chords of the 

 ninth and seventh, also the chord vii^^. Besides these, 

 the dissonance V9 breaks up into three triads. All 

 are given below in the order of their mention.
