HARMONIC & ENHARMONIC
Text: "If a violin string is bowed steadily, the frequencies of the partials of the resulting complex tone will be integral multiples of the lowest (fundamental) frequency, and the partials may properly be called harmonics. If, however, the same string is struck or plucked and then allowed to vibrate freely, the frequencies of the partials in the airborne sound and the frequencies of the corresponding modes of vibration are, in general, no longer exactly in the ratios of integers, and the partials and modes of vibration are inharmonic."
