I have a spread sheet I use that has similar informatin like what you have in the note12octave page. I take it to sub octaves.
I equate the 'period' of a bar or note of music, as well, to sub octave frequency.
The period of a note, if selected from a list of periods in that same key, from a sub octive, will have a significant bump up in it's effect. So a song, say, written in the key of C might be good to have periods that reflect sub octive C, F or G.
but you can choose it for how it sounds, of course.
also, for delay and echo effects I tend to like to add echos with period of repeats that are also either I, IV , or V of the key.
of course how does it sound is very important.
resonance and ringing .
the beat ought to be a period that is the key of the song. What that also means that the tempo would have to change, in that case, if the song is played in a different key.
Of course, these are just concepts for a particular way to reinforce sound.
Real muscians play what sounds good.
