Acoustic Geometry 17

Timbre Space (Acoustic Morphospace)

An interactive multidimensional acoustic space where sounds that are acoustically similar cluster together geometrically. Discover unexpected analogies where analog synthesizers mirror acoustic reed dynamics or marine vocalizations reflect soft-tissue deformations.

Newton's 1704 Optical Analogy (Opticks)

Sir Isaac Newton explicitly correlated the seven spectrum colors to the seven steps of the musical octave (Dorian mode), arguing both were manifestations of divine harmonic proportions.

Scriabin's 1910 Circle of Fifths

Russian composer Alexander Scriabin built the *Clavier à lumières* for his symphony *Prometheus*, projecting colored light beams that synchronized with the circle of fifths and mystical chord intervals.
