Preparing the sound landscape…
RECORDED SOUNDHEIGHT = SPECTRAL LEVEL
Move the slider. Pitch, timing and timbre change together; the surface is recomputed from the rendered sound.
TWO POSSIBLE ROUTES
TO MUSICAL STRUCTURE
Abstraction Do we make music by simplifying natural sound?
Induction Derive musical structure from its regularities?
Transform one phrase in controlled steps. Separate pitch, timing and timbre; compare flute and piano. Establish what MI distinguishes, then test whether those differences predict human judgments.This pilot probes model sensitivity. Perceptual object formation and induction remain open research questions.
