Re: Pitch learning
Hi Susan and Linda,
I agree that there is a large degree of variability
in performance intonation. (By saying variability,
I don't mean random
variation ... for masters it is of course expressive).
But huge variations are
also present for Western music played on non-fixed
tuning instruments, such as violin, or in
vocal performance. Every study of which I am aware
confirms this basic point. This, as it sounds like you
would agree, makes the very measurement of
mean frequency suspect. However, it doesn't
mean there is no tuning system.
Is there more variability in Indian or Chinese music?
I don't know. I have never seen a comparative study.
And, by the way, these are empirical issues, not political

Concerning Indian music: I studied North Indian classical singing
Ustad Vilayat Khan. He sometimes demonstrated different versions

improvisation in Asian musical culture to say that Asian music has
and fixed intervals. It is part of the fa;se stereotype of Asians as
memorizing and not being creative. Each raga is different. Each
performance of a raga is different. The performances of the same
different gharanas are different. A master can elaborate different
subtle intonations of the pitch and color of a note among
within a raga, or within a performance. That is part of the
subtlety of a
master. When real master is performing you never know what
musical idea he or she is going to follow. The intervals of a
fifth and a
fourth exist, but I have even heard Vilayat Khan demonstrate
(the base note) slightly off pitch as an expressive device.
in Indian music is not a mindless outpouring of whatever junk

development of a musical idea.
As for Chinese music, how can be there "a system" when there are 400
different kinds of Chinese opera alone? The tuning of the strings
ch'in and the zheng by master performers can be analyzed, but then
will go all over the place in expressive intonations and pitch
curves in a
performance. But if you want to know about Chinese music, Bell
Pittsburgh is the expert, not me. I had an introduction to
in the Chinese literature classes of Prof. Yu-Kung Kao at
Princeton and I
took some lessons on the zheng. I couldn't take the regimented
conservatory method of teaching the zheng that I was being

Sorry, it IS clear from this study. The authors reported that
generalization over the distance of two octaves is even stronger
than that over the distance of one octave. This finding
rules out the possibility that the monkeys generalized

possibility is that the monkeys, the same as humans, have an
