Here ends the analysis of the common report of the 

 harmonic relation and form of each individual tone 

 in this melody. However, the harmonic analysis is 

 not yet complete. As we sing and think over this 

 melody we observe in addition to the fact that each 

 tone reports a harmony another fact, namely, that 

 certain rhythmic groups of these tones relate to and 

 report the predominance of a specific harmony, which 

 I have already named the regnant harmony. Thus 

 in each small phrase we observe a change from one 

 regnant harmony to another, now the Tonic, now 

 the Dominant, as marked in the example. Thus the 

 first small phrase changes from Tonic to Dominant, 

 the second from Dominant to Tonic, and so on. Reg- 

 nant harmony being the special subject of the next 

 chapter w^e need pause here only for a few observa- 

 tions. We note that these changes of harmony are 

 instantaneous and recurrent; hence the implication 

 of rhythm in causing these changes. So far I have 

 accounted for the genesis of but one regnant har- 

 mony, the Tonic, since every conceivable succession 

 of Tonic-components generates the Tonic-harmony
