Re: Pitch learning

I am going to use some terms from musical analysis in a nonstandard way. 
I am using these terms as musical terms and not as technical terms in the
field of psychology or perception, because I do not know whether or how
this paradigm is matched to perception.  With respect to musical form we
speak of background and foreground.  Using such terms in this discussion,
one could state that the presence of perfect fourths and fifths and other
intervals of just intonation are in the background.  The deviations in
intonation are in the foreground.  It's obvious that many cultures rely on
some exact ratio intervals.  A deep understanding of the musical
creativity and artistic expression will come from appreciating the
foreground.  Too many ethnomusicologists in the old days reduced
non-Western melodies to Western scales and even Western notation, and the
result was that non-Western musics seemed primitive.  An inexact "octave"
expresses something different from an ocave.
