Since
then I have, as it happens, spent a fair amount of time listening to and reading the
work of Frank Denyer, who in a 2009 article entitled "Some
Thoughts About Linear Microtonality" makes the fascinating
observation (which he has empirically tested) that musicians tune
intervals – even octaves – differently if they can sound both
pitches simultaneously and if they cannot. He comments that "This
appeared to demonstrate two different ways of being 'in
tune'.
The question is: being
in tune with what?"
This
seems to me a crucial question.
Tuning
is relational. Yes, it provides a route to extrapolate from strictly
musical questions to those with wider social import. But even before
we get to that point it indicates that there might be a
continuum between the literal and figurative uses of the term "in
tune". Starting from unusual pitch relationships (that which
appears out of tune is just an unfamiliar way of being in tune), we
could move to the idea that pitch might not even be what one is
attempting to be "in tune with" at that particular moment.
Can one be "in tune" timbrally, rhythmically or dynamically? We know that the difference between what we hear as a timbral change and a pitch change can be fundamentally a matter of frequency - as, of course, is rhythm. Composers
as diverse as John Zorn and James Saunders have produced work whose
sounds express the extent to which an ensemble is "in tune"
temperamentally. (In the sense of their personalities and behaviours,
that is, not their chosen tuning systems, although perhaps this
polysemy – originating in the Latin for a "correct mixture"
– is not without interest.) From that point, the concentric circles
can go ever wider.
Denyer
observes: "While working in Kenya’s Kerio Valley I noticed
that lyre players could consider two strings to have an octave
relationship and be acceptably in tune even when one of them
was more than a hundred cents away from the 2:1 harmonic ratio. This
is probably because they employ a gamut of just five notes, somewhat
casually spread out between the octave, so the identity of adjacent
notes is never compromised, and the essential pitch relationships
remain the same, making them indeed in tune."
Also
interesting is the sense of boundaries evoked by the term: we can be
"in" and "out" of tune. We can also be "in
bounds" or "out of bounds" (grammatically cognate
constructions), and there are "upper bounds" and "lower
bounds". Hence thinking about the co-ordination of pitch and
other musical parameters brings us to think about space. A number of
the "paragraphs" of Cardew's composition (in particular
Paragraph 4, for voices, drumming on cushions, gueros & organ,
and Paragraph 7, for voices) made clear to me that the relationship between
physical space and pitch space is not purely metaphorical.
Different pitches really do have differently sized sound waves, and
contrasts of proximity to sound source and of volume seem to help make
one aware of this.
There's a lot here that I need to ponder!
