As another lister has said, yes. My entire understanding of how the voice
works changed. By understanding what a frequency spectrum represents - ie
how that spectrum relates to the voice that made it, the source and the
filter - I had a whole new mindset of interrelationships, and causes and
effects. Instead of a sack full of unrelatable tricks, I had a cohesive
framework no more arcane (though far more miraculous) than a car engine.
Even the bits we don't yet understand became like black boxes where a known
input produced a known output, even though how it made the transformation
wasn't understood.
I would point out that I, personally, don't use spectral analysis in my
teaching, only the *concepts*. On the other hand, I do a lot of spectral
analysis in my research, so it is being constantly reinforced.

The (computer-based) frequency spectrum displays what the microphone hears.
The spectrum is thus a product of the sound made, the room acoustics, the
microphone's sensitivity characteristics, and the computer program
calculating the spectrum. Human hearing is a product of the sound made,
the room acoustics, the individual hearing mechanism, the mental processing
of that sound, and individual subjectivity (psychology). I should love to
see more perceptual research done, but it's hard to get inside someone
else's mind.

Drs Van Doorn, Thorpe and Callaghan (Uni of Sydney, USyd and Uni of Western
Syd) have just been awarded an Australian Research Council Large Grant over
3 years to study the use of visual spectral feedback in singing. This
follows a smaller study which was very promising.
Kind regards
