Towards
an Absolute Pitch Understanding of Classical Form
James
Mackay, Loyola University
'Composers compose with
notes, not keys,' one of my professors liked to
claim. And indeed, a single
note, strikingly introduced and then
extensively developed, can
play a major role in shaping a work's tonal
rhetoric. In this paper, I
explore an absolute pitch conception of musical
space in Classical style
(where retention of, and departure from a single
pitch become important to a
work's inner logic), and trace the progression
and expansion of this
technique from Haydn through Schubert.
The ability of anomalous
pitches to influence a work's tonal shape is
contingent upon there being
a conventional, expected tonal plan against
which to juxtapose. Haydn
was the first to explore playing individual
pitches against the
standard I-V-I departure-return model that is typical
of Classical works. Such
pitches could be used to intensify a work's
expected tonal direction,
or to create a musical subplot that runs parallel
to the conventional tonal
unfolding. If a pitch is unconventional in its
immediate context, the role
of the composition might be to create a
suitable rationale for it
as the work unfolds.
We will explore three
examples of this technique: the finale of Haydn's
Piano Trio in C major (Hob.
XV: 27), the opening movement of Beethoven's
'Ghost' Trio (Opus 70,
no.1) and the outer movements of Schubert's Sonata
in B-Flat, D. 960. It is
tempting to examine form or harmony to discern a
composition's logic.
However, analytical insights may be obtained by
exploring the introduction,
recurrence and retention of important pitches.
Pitch-class invariance
plays a vital role in certain works as far back as
Haydn: though far from the
whole story, it is an oft-neglected but
important component of a
work's musical rhetoric.
