I have developed in previous posts the method of composing a melody over a chord progression based on the simplicial sub-melody , which has one note per chord.
On the other hand it is widely known in popular and folk music the structure of a melodic theme over a chord as having an arpeggio (harmonic-melodic) part and a tail (chromatic) part (see e.g. post 421 )
The linking of thee two methods is the obvious that we substitute the one note of the simplicial sub-melody, with the arpeggio part of the melodic theme, and we leave the tail as the bridge of two notes of the simplicial submelody.
If we eliminate thus the tails (chromatic bridges) instead ofte simplicial submelody we get an arpeggio submelody . or harmonic submelody.
There is an issue of beats per minutes though. If we utilize the simplicial submelody method then there are one or few only notes per underlying chord while if we utilize the arpeggio-tail method there are many notes per underlying chord. This suggests that the simplicial submelody method has double the number of beats per minute compared to the alternative composition with the arpeggio-tail method.
Obviously by letting more time for each chord, the melodic theme will have larger part as arpeggio (e.g. 2/3 of it time) and less (e.g. 1/3) as tail. This is according to the older tradition in folk music.
E.g. a full 15 syllables poetic line (in 15-sylalble poetry) could be only two chords 5M7-> 1M or
1M->5M7 etc.
For a 15-sylalbes poetic lyrics, a full 15 syllables poetic line of total syllables (4+4)+(4+3)=15 would correspond to a single melodic theme A1 , or B1 , C1, A2 etc. and thus here to 2 chords. This is convenient for the arpeggio-tail method of composing melodies. While the simplicial sub-melody method would require 4 chords per 15-sylalbles poetic line. (see also post 428)
