   Tune.]
   1. Sound, or the character of a sound, or a sound considered
      as of this or that character; as, a low, high, loud,
      grave, acute, sweet, or harsh tone.
      [1913 Webster]

          [1913 Webster]

   Note: 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]

   Note: 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.
         [1913 Webster]

   5. (Med.) That state of a body, or of any of its organs or
      parts, in which the animal functions are healthy and
      performed with due vigor.
      [1913 Webster]

   Note: In this sense, the word is metaphorically applied to
         character or faculties, intellectual and moral; as, his
         mind has lost its tone.
         [1913 Webster]

   6. (Physiol.) Tonicity; as, arterial tone.
      [1913 Webster]

            drudgery of private and public business.
