ACCENT AND REGNANT HARMONY 



117 



harmony to another reported by the efficient accent 

 of melody each of the seven diatonics appears now 

 as a regnant tone, now as a bytone. Thus what is 

 a regnant harmony at one moment is transmuted 

 into a byharmony the next moment and the reverse. 

 Our next example presents I with bytones, V with 

 bytones and IV with bytones, and all these regnant 

 harmonies and byharmonies are diatonic. A har- 

 mony is classed as diatonic when all its concomitants 

 or components are diatonic.

N.B. 



Except at N.B. all the above regnant harmonies 

 are consonances. Except at N.B. the second tone in 

 each measure is a bytone, but this second tone in 

 every measure including N.B. is in cadence. With 

 one exception all the byharmonies are consonances 

 in cadence. The exception is reported by /a during 

 the regnancy of I when the byharmony is a four- 

 tone dissonance as shown by the report of /a as 7. At
