"The Character of Sound"
by Dieter Ennemoser

The Musical Metre as a Consequence of the C37 Pattern

This suggestion came from my sister Heidi Ennemoser who, in the course of her training as a conductor,
experimented with the effect of various musical tempi on the perception of the listener.
She found out that different people, when hearing the same tempi, had the same or similar feelings.
The fact that these results were quite decisive lead me to the question: Is the perception of tempi somehow
linked to the C37 pattern and the perception of sounds? One particular quality of the C37 pattern is its
octavability in both directions.
This implies that by halving the C37 frequencies several times one could get within a frequency range of
"beats per minute".
What would the metronome numbers resulting from these calculations be like? Would my expectations be
proved wrong?

After some calculations, I had established the following metronome numbers:

61,4 63,0* 66,8 70,3 75,5 82,8 88,1 93,0 100,0 109,0 113,7 123,0 126,0*

134,0 141,0 151,0 166,0 176,0 186,0 200 beats per minute.

(* = new, not in the book)

I made measurements and comparisons and came to the following conclusions:

The C37 tempi feel natural and full and in harmony with the body. The body seems to respond to them.
Just as a swing can be made to go ever higher by a series of small repetitve pushes, so the correct
tempi induce distinct reactions in the body.
Even with the sound of a pulsating metronome (it is an electronic one with a little loudspeaker) I could
detect differences due to the tempo: The beating of the C37 tempi appeared clearer, firmer, and more forceful.
Intermediate tempi sounded nasal and flat, as though striving to recover from an unstable position.
A new question in evitably emerged: How does a 3/4 time or a 6/4 time fit into the system?
Are only the whole bars important or the individual beats also? - It turned out that both the bar tempo as
well as the beat tempo (i.e. treble the metronome number for 3/4 time) should follow the C37 pattern.

This, of course, means a reduction in the number of tempi available. Calculation shows that only the following
metronome numbers meet these criteria: 61.4 66.8 75.5 82.8 100.0.

These tempi, because of their stronger body resonances, also appear very forceful in (2/2) time whereas the
remaining five tempi 54.5 70.3 88.1 93.0 and 113.7 suggest lighter, more graceful themes and may be able
to express more subtle registers.


What can be concluded from these results? Our perception of tempi reveals itself as the extended oscillation
of our constituent atoms! This is how we share a specific common relationship; who we are, what we are made of, and what we express through music. This specific relationship is called musicality.

(Naturally these figures, as those for the frequencies noted in the previous chapter, only represent the current
extent of my research and I make no claim for their accuracy or cempleteness).
We perceive musical tempi not as an objective physical phenomenon but through the unconsciously felt vibrations of our own bodies. That is why, in century of technical progress, the determined attempts to impose new structures on music through mathematical formulae have been unable to alter anything. And when pedantics try again and again to deny the nature in us and declare everything to be relative, nature always reemerges as the dominant factor.

Any musician who has played in an orchestra knows the feeling of suddenly tuning into the same beat
transmitted from conductor to player to player, or from player to player to conductor, or occasionally even from
listener to conductor to player to player.

A conductor will not lose his creative freedom because of the discovery of the existence of natural vibrations as
one might first assume - not any more than the painter would be restricted in his creative art by a knowledge of
the functioning of the human eye. Knowing these natural relationships, he can become increasingly conscious
of the effect that the choice of tempi, and the increasing or reducing of speed, and tempo shifts have upon the
expressive value of music. He will also realize the importance of this instinct, will cherish it and perhaps even
revive experiences or abilities buried for a long time.

"Our perception of tempi reveals itself as the extended oscillation
of our constituent atoms!". How on earth Stefano, can you buy the psychobabble without a sense of critic? You, the guy with the most reductionist device ad hand (IVIE) ???????

... that's a cut & paste affaire, you know... I used C-37 in early '90s (on speakers paper, as per Sound Practices magazine Ennemoser's review) and, as I saw it quoted again on Audio Consulting AG's site, I just wanted to undust the topic, for me and fellows... yes, you're right, IVIE is sort of audio hypes-annihilator (tm;-))), BUT also a friendly gear which support and confirm... a Linus' blanket, maybe...
The critc consists in... not criticizing... as you noticed I didn't added ANY comment on my part.
Also, another red-wire for reading: because it's me writing and joking and... as I know what Thomas Mayer's charging for the WE 437A/801A preamp project (which is not EUR 109.000, of course...), I wished to let people look at a different approach as the Switzerland-made preamp price-tag suggest... i.e. sell one and be happy.

Then I noticed the old-swamp wooden arm (EUR 14.000, BUT C-37 treated...) and voilà!

I'm sure that nothing is unimportant, in audio, BUT... the "fox" in "The Little Prince" may sounds quite dangerous in its statement "... see with the heart... etc...)as Ennemoser's varnish and science... but all the above exists, and still quite unknown, so better spreading...

Sounds better, now?!?

Definitely better, though I'd like to be able to tell your own opinion from a quote. Especially here in the middle of the night...
