Dear bayabada,
Re: perfect pitch ...
Many (though not all) of the great composers throughout history had
perfect pitch, so it's nothing new nor controversial at all. It's easily
demonstrable and universally accepted, having been been well studied and
documented scientifically. (See my response to Coldrayne above.)
Those with perfect pitch can distinguish musical tones as easily as
someone with normal vision can distinguish colors in all its various
shades. Moreover, perfect pitch can be learned by anyone who wants to
develop it. There are well-established protocols which have been
objectively demonstrated to be nearly always effective. (The only
"failures" in these studies were due to the time-constraints of the
study-periods. Those who failed to develop perfect pitch in the time
frames of the studies eventually go on to develop it at their own pace.)
What's also true is that perfect pitch is NOT a predictor of success in a
musical career. Someone without perfect pitch can become as successful a
musician as someone with perfect pitch. What's much more important in
musicianship is "relative pitch," the ability to discern the intervals
between musical tones. Relative pitch is absolutely essential to becoming
a successful musician, and that is why "ear training" courses in music
conservatories and universities stress the development of relative pitch.
Some programs are starting to also teach perfect pitch, but it's not vital
for musical success, so it's not stressed as much as relative pitch.
As for why some people seem to "naturally" have perfect pitch, the best
explanation based on the evidence to date is that the "natural" perfect
pitchers were exposed to music and musical education very early in their
lives (before age 7, the earlier, the better). They were exposed to rich
tonal stimuli during a vital stage when the language areas of their brains
were developing. Indeed, the best analogy we have regarding perfect pitch
(and musical ability in general) is "language." Just as it's very easy for
kids to learn languages during a critical stage in their development, so
it is easier for them to learn perfect pitch (intentionally or not) when
they are young. And just as it's very difficult to get rid of a foreign
accent after a certain age, so it becomes harder (but certainly not
impossible) to develop perfect pitch later in life.
The sooner someone is exposed to the richness of musical tones and taught
to REALLY listen to them and notice their differences, the easier it will
be for them to master perfect pitch. Some children are able to notice
these differences on their own, and thus develop the ability by
themselves. In the process, though, they had to undergo a self-training
period where they learned by trial and error to distinguish the various
tones. They did naturally what we can now do intentionally, but everyone
who has mastered perfect pitch goes through essentially the same process
when developing the ability.
Anyway, others have written much more extensively and eloquently about
perfect and relative pitch than I can hope to do here, so if you're
interested, here are good places to start:
http://en.wikipedia.org/wiki/Perfect_pitchhttp://en.wikipedia.org/wiki/Relative_pitchPerfect pitch is a great example to show how the objectivity of the
scientific method can be used to carefully study, understand, and
effectively teach a certain human ability. As I'm sure you know, there
are many other abilities which humans manifest, which we are currently
trying to understand, things like total recall, genius-abilities in music,
art, and math by idiot savants, etc. Hopefully humanity will be well
served as we better appreciate how to develop our full potentials. May we
be guided by a rational, objective spirit toward that end.
Best,
