psychological effects of musical frequency ratios - chord root transitions

Daniel Wolf writes: "Isn't it interesting that each prime can divide the tonal
space in a unique way". A factor in psychological effect of music in addition
to that of frequency ratios in individual chords is the interval over which
a chord root transition is made - say by a fifth, by a 9/8 major second, by a
6/5
minor third, etc. Also, do small deviations - say by five cents - from just
of the interval between the roots of successive chords affect the
psychological
effect of the part of the musical phrase formed by these two successive
chords?

Historically the idea of the 3/2 consonant fifth appeared long before there is
evidence that two or more harmonizing parts were frequently employed in music.
Of course the second note of a melodic interval would be mentally "harmonized"
with the first note. I believe many people can easily detect a melodic fifth
which is off from just by five cents.

Thinking as I write, I believe that there are objective, scientifically
demonstrable
relationships between pitch relationships in music (among all the other
factors)
and the psychological effects of the music. Also, it would seem that if our
understanding of the effects of these factors were deepened, it would be
possible to create music which is even better at creating various specific
psychological effects than is present day music. Thus Beethoven's music is
emotionally moving for quite a few people. Why? We would say that Beethoven
was an inspired genius who had a feel for what musical edifices would be
really
effective psychologically. However, I believe that if - and this is beginning
to
seem possible today - we really understood more quantitatively how music
achieves its psychological effects, music could be produced - by individuals
who
had deep understanding of this and had enough of Beethoven's gifts to
effectively
use this understanding - which would equal and even surpass the music which
Beethoven produced.

I believe that relatively fine nuances of tuning are much more important
towards
music's achieving the psychological effects which it has the potential to
produce
than has generally been appreciated in the recent past. Many are now aware of
this
and this is very encouraging.
