   m['e]lodie, L. melodia, fr. Gr. ? a singing, choral song, fr.
   ? musical, melodious; ? song, tune + ? song. See {Ode}.]
   1. A sweet or agreeable succession of sounds.

            Lulled with sound of sweetest melody. --Shak.

   2. (Mus.) A rhythmical succession of single tones, ranging
      for the most part within a given key, and so related
      together as to form a musical whole, having the unity of
      what is technically called a musical thought, at once
      pleasing to the ear and characteristic in expression.

         harmony is a consonance or agreement of tones, also a
         succession of consonant musical combinations or chords.
