Music making is not something particularly difficult

All that needs to be remembered is choosing one or more of the
1 3 5 7 9 11 13 notes above bass at any particular instant.


For example if Bass is A total Harmony can be:


A bass and C E B (choosing just the 3rd, the 5th and the 9th)


(Whether any interval will be major, minor, diminished or whatever will be automaticaly dictated by the key or scale at that stage of the music composition. The scale defines what flats or sharps must be used. For example if the key had been A major ie all C,F,G sharp the above code of A9 would had been played:
A bass and C#  E  B
Ie the chord or Harmony would have been
A major 3rd major 9th instead of A minor 3rd major 9th on Veridis Quo - Daft Punk writen in D Dorian scale, ie all notes white or natural)


So everything is just 1 for bass with 3 or 5 or 7 or 9 or 11 or 13 or 15 above bass. When the note names (or numbers if your like) are chosen according to what we want, the notes can be arranged to any octave, any instrument or whatever we see fit to what out brain wants or likes.


If you follow a score of a good symphony, a good pop song or whatever, this can be verified or not verified. Most likely verified.
