Attempted to replicate Dr. Anton Reiss's 1989 paper on Nova Hart's vocal pitch distribution.

Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes.
Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents.

Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid.

Line 11: 'The key is the pitch of my voice.' The vocal pitch IS the demodulation clock for the subcarrier.
