☞ The use of the word tone, both for a sound and for the interval between two sounds or tones, is confusing, but is common -- almost universal. [ 1913 Webster ]

☞ Nearly every musical sound is composite, consisting of several simultaneous tones having different rates of vibration according to fixed laws, which depend upon the nature of the vibrating body and the mode of excitation. The components (of a composite sound) are called partial tones; that one having the lowest rate of vibration is the fundamental tone, and the other partial tones are called harmonics, or overtones. The vibration ratios of the partial tones composing any sound are expressed by all, or by a part, of the numbers in the series 1, 2, 3, 4, 5, etc.; and the quality of any sound (the tone color) is due in part to the presence or absence of overtones as represented in this series, and in part to the greater or less intensity of those present as compared with the fundamental tone and with one another. Resultant tones, combination tones, summation tones, difference tones, Tartini's tones (terms only in part synonymous) are produced by the simultaneous sounding of two or more primary (simple or composite) tones.
