425. The major harmonic 5-cycle 6 (n or M) 2 (m or M) 5M 1M 4M and the minor harmonic 5-cycle 3(m or M) 6 (n or M) 2 (m or M) 5M 1M in composing songs.

In a diatonic scale we may have harmonic cycles of 5 chords e.g.

3m->6m->2m->5M->1M which has more  minor chords than major and may be called the minor harmonic 5-cycle and the

6m->2m->5M->1M->4M which has more major chords than minor chords and may be called the major harmonic 5-cycle.

Upon these cycles we may add the 5# blue note (from the harmonic minor Aeolian mode) or other blue notes by converting major chords to minor chords etc.

So when composing songs we may start the couple with the minor harmonic 5-cycle and end at the refrain with the major harmonic 5 cycle.


A characteristic example is the melody by Luiz Bonfa Black Orpheus, or Manha de Carnaval (Morning carnival) a melody from a film, composed by which nevertheless has an original version under the name samba de Orfeu, which is a bit different and more happy version of the melody.

E.g. see for the sad version Manha de Carnaval

The sad version Manha de Carnaval is utilizing the minor harmonic 5-cycle of chords

3m->6m->2m->5M->1M . It alters also the 3m to 3M7

while the happy version is utilizing the major harmonic 5-cycle

6m->2m->5M->1M->4M . 

It alters also 6m to 6M7. I addition at a point it alters 5M to 5m and 4M to 4m !
