ON CEREBRAL DOMINANCE
for flute, violin, viola,
bass clarinet, piano and vibraphone. 1987. 7 minutes. Score and
parts available through the composer.
The medical term On Cerebral Dominance refers to the specialized
way each half of our brain operates and the dominion it has over
certain bodily and mental functions. The left is analytical, compartmentalizing
and with attention to detail while the right is holistic, intuitive
and with a uncanny ability for seeing or creating patterns. During
the composition of On Cerebral Dominance, I was becoming
aware of two general influences at odds with each other in my
own work. The American and the European (rather narrowly labeled
and naively represented in the piece with the jazz-like and the
baroque-like idioms used throughout). Their relationship has been
dynamic, strained at times, but never completely at rest. They
have been kept separate and yet integrated in the same way that
the two hemispheres of our brain (contradictory and complementary
at the same time) perform one composite function without completely
understanding each other. Think of the two musical idioms in this
piece as the two halves of the brain: one tonal, baroque-like,
the other atonal (actually twelve-tone), jazz-like. Each of them
negates the other and downplays the other's achievements. When
the tonal side makes an attempt at minimalism, the other side
dismisses it, comparing it to a malfunctioning turntable stylus
which skips constantly. Similarly, when the atonal side makes
formal presentations of the twelve-tone row, the opponent laughs
victoriously because the resultant vertical sonorities are in
fact triadic tonal harmonies. This split across styles is accompanied
by a timbral split across the ensemble resulting in two instrumental
groups, the quartet of 'sustain' instruments (flute, violin, viola.
bass clarinet) and the duo of 'percussive' ones (piano and vibraphone).
In performance trying to stay on track while the music crosses
these dividing lines can be a hair-raising experience. From past
performances of On Cerebral Dominance, I have come to the
conclusion that, while a conductor might be useful during the
early rehearsals of the piece, he/she becomes a hindrance when
the ensemble picks up speed and plays up to tempo. It is much
preferable if the musicians stay on track by listening attentively
to each other rather than rely on visual cues from a third party;
there is just not enough time to respond accurately to such cues.
Enjoy!
