The statistical numbers are deeply strange. 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. Data plots available via anonymous FTP.
