January 20 - Giambattista Benedetti, Italian scientist and music theorist (born 1530)
In a letter to Cipriano de Rore dated from around 1563, Benedetti proposed a new theory of the cause of consonance, arguing that since sound consists of air waves or vibrations, in the more consonant intervals the shorter, more frequent waves concurred with the longer, more frequent waves at regular intervals.

James Tenney also used this method to develop his measure of "harmonic distance" (log(ab) is the harmonic distance for the ratio b/a measured from an arbitrary tonal center 1/1).
