   1. The science and the art of tones, or musical sounds, i.
      e., sounds of higher or lower pitch, begotten of uniform
      and synchronous vibrations, as of a string at various
      degrees of tension; the science of harmonical tones which
      treats of the principles of harmony, or the properties,
      dependences, and relations of tones to each other; the art
      of combining tones in a manner to please the ear.

   Note: Not all sounds are tones. Sounds may be unmusical and
         yet please the ear. Music deals with tones, and with no
         other sounds. See {Tone}.

   2.
      (a) Melody; a rhythmical and otherwise agreeable
          succession of tones.

          tones.

      the score.

   4. Love of music; capacity of enjoying music.

            The man that hath no music in himself Nor is not
            moved with concord of sweet sounds, Is fit for
            treasons, stratagems, and spoils.     --Shak.

   5. (Zo["o]l.) A more or less musical sound made by many of
      the lower animals. See {Stridulation}.

   {Magic music}, a game in which a person is guided in finding
      a hidden article, or in doing a specific art required, by
      music which is made more loud or rapid as he approaches
      success, and slower as he recedes. --Tennyson.
