106 THE NATURE OF MUSIC 



are named regnant tones. The tones lying over and 

 under and cadencing up and down into the regnant 

 tones are named bytones. Bytones are components 

 of other harmonies named byharmonies. Regnant 

 harmony, regnant tone; byharmony, by tone; let us 

 bear these terms and their meanings in mind. The 

 first regnant tones to appear in melody were do, mi, 

 sol, of the regnant Major Tonic : the first bytones to 

 appear were the original cadence-tones re, la, fa and ti, 

 which as we have seen arose in relation to the Major 

 Tonic-harmony. Of these embryonic melodies there 

 are two types: first, those lowest in the order of 

 development composed of regnant tones only and 

 representing harmonic perception and harmonic rela- 

 tion in their incipiency and within their narrowest 

 confines ; second, those next in order of development, 

 which introduce bytones along with the regnant tones, 

 thus marking an advance in harmonic perception 

 and relation. Melody based on one regnant harmony 

 could advance no further; the second type of melody 

 brings its first chapter of development to a conclusion, 

 and this first chapter of melody corresponds with 

 the first developmental chapter of harmony. From 

 first to last the development of melody is dependent 

 on that of harmony; melody could not advance 

 another step until a second regnant harmony arose 

 in relation to the first. When this step was taken 

 a significant change was suddenly effected, for at one 

 bound harmonic relation expanded from that of 

 bytone to one regnant harmony to that of one reg- 

 nant harmony to another regnant harmony; at one 

 bound melody entered into a new region of inexhaust-
