6 – Macrotemporal listening dimensions: Movement, Pulse, Rhythm and Melody
107
Throughout the solo, the movement towards the final climax is a process
of spatial expansion.
Hawkins' solo displays freedom of spatial shaping as well as freedom of
temporal shaping. The melodic curves move in weightless fashion over the
regular pulse pattern, and the target tones of the curves are flexibly related
to the beat, sometimes hitting a beat, more often landing unconcernedly
and with ease somewhere between two beats.
Freedom in the shaping of melody is also heard in the variability of
pitch height, timing, timbral quality and vibrato shading which can merely
be approximated by the notated transcription.
The timbral color of the instrument can change from phrase to phrase,
within a phrase or from tone to tone. In the lower register, approximately
below C4, the tone quality is warm, sonorous and diffuse. In the higher
register, the tone is clear, bright and dense, or it may be given a sharp edge
as heard in the high-register leaps of the final section. In the swiftly rising
and falling melodic lines, the saxophone sound changes smoothly between
rich, diffuse sonority and luminous density. This is an imponderable
quality of the melodic flow.
Pitch height is not confined to the steps of the diatonic or chromatic
scale, it is subtly variable, gliding, bending and colored by vibrato. The
vibrato is a personal expressive feature in Hawkins' mode of playing,
adding a quality of breath and bodily presence to low tones and a sensation
of exhilaration to high tones.
Hawkins' solo is imbued with the quality of swing. Swing is a subjective
sensation of a regularity which is not strict or mechanical, but living and
flexible. The variations of timbre, pitch height and vibrato of each single
tone are essential contributions to the feeling of swing. Two other factors
are essential; the inherent flexibility of the underlying regular pulse
pattern and the variable relation and tension between the movement time
of the soloist and the pulse time of the rhythm section.
