  Harmonic \Har*mon"ic\ (h[aum]r*m[o^]n"[i^]k), Harmonical
  \Har*mon"ic*al\ (-[i^]*kal), a. [L. harmonicus, Gr. "armoniko`s;
     cf. F. harmonique. See Harmony.]
     1. Concordant; musical; consonant; as, harmonic sounds.
        [1913 Webster]
              Harmonic twang! of leather, horn, and brass. --Pope.
        [1913 Webster]
     2. (Mus.) Relating to harmony, -- as melodic relates to
        melody; harmonious; esp., relating to the accessory sounds
        or overtones which accompany the predominant and apparent
        single tone of any string or sonorous body.
        [1913 Webster]
     3. (Math.) Having relations or properties bearing some
        resemblance to those of musical consonances; -- said of
        certain numbers, ratios, proportions, points, lines,
        motions, and the like.
        [1913 Webster]
     Harmonic interval (Mus.), the distance between two notes of
        a chord, or two consonant notes.
     Harmonical mean (Arith. & Alg.), certain relations of
        numbers and quantities, which bear an analogy to musical
     Harmonic motion, the motion of the point A, of the foot of
        the perpendicular PA, when P moves uniformly in the
        circumference of a circle, and PA is drawn perpendicularly
        upon a fixed diameter of the circle. This is simple
        harmonic motion. The combinations, in any way, of two or
        more simple harmonic motions, make other kinds of harmonic
        motion. The motion of the pendulum bob of a clock is
        approximately simple harmonic motion.
     Harmonic proportion. See under Proportion.
     Harmonic series or Harmonic progression. See under
     Spherical harmonic analysis, a mathematical method,
        sometimes referred to as that of Laplace's Coefficients,
        which has for its object the expression of an arbitrary,
        periodic function of two independent variables, in the
        proper form for a large class of physical problems,
        involving arbitrary data, over a spherical surface, and
        the deduction of solutions for every point of space. The
        functions employed in this method are called spherical
        harmonic functions. --Thomson & Tait.
     Harmonic suture (Anat.), an articulation by simple
        apposition of comparatively smooth surfaces or edges, as
        between the two superior maxillary bones in man; -- called
        also harmonia, and harmony.
     Harmonic triad (Mus.), the chord of a note with its third
        and fifth; the common chord.
        [1913 Webster]

From The Collaborative International Dictionary of English v.0.48 :

  Harmonic \Har*mon"ic\ (h[aum]r*m[o^]n"[i^]k), n. (Mus.)
     A musical note produced by a number of vibrations which is a
     multiple of the number producing some other; an overtone. See
     [1913 Webster]

From WordNet (r) 3.0 (2006) :

      adj 1: of or relating to harmony as distinct from melody and
             rhythm; "subtleties of harmonic change and tonality"-
             Ralph Hill [ant: nonharmonic]
      2: of or relating to harmonics
      3: of or relating to the branch of acoustics that studies the
         composition of musical sounds; "the sound of the resonating
         cavity cannot be the only determinant of the harmonic
      4: relating to vibrations that occur as a result of vibrations
         in a nearby body; "sympathetic vibration" [syn: harmonic,
      5: involving or characterized by harmony [syn: consonant,
         harmonic, harmonical, harmonized, harmonised]
      n 1: a tone that is a component of a complex sound
      2: any of a series of musical tones whose frequencies are
         integral multiples of the frequency of a fundamental
