and becomes arbitrary selection from infinite possibility space. In
Kernel Engagement
Works within the kernel’s native ground; the structural gap is present but never encountered.
Evidence
Speech melody transcription generates cascading constraints the composer didn't choose — irregular phrase lengths, specific pitch contours, and durational patterns all emerge from the speech recordings' inherent properties, not Reich's compositional decisions.
Territory
The string quartet writing uses conventional tonal harmony and voice leading. The transcribed speech melodies are rendered in diatonic pitch space with standard cadential patterns and fifth-based chord progressions.
Constitutive depth
The speech recordings generate endogenous constraints — pitch contours, rhythmic patterns, and phrase durations that Reich must satisfy but didn't select. These emerge from the mechanism's operation (speech has inherent melodic properties) rather than compositional choice.
Legibility
The fifth-based tonal relationships remain naturalized and invisible — audiences hear the work as minimalist process music without perceiving the underlying harmonic infrastructure that makes the transcribed melodies coherent as tonal material.
