From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]:

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  more  simple  harmonic  motions,  make  other  kinds  of  harmonic
motion.  The  motion  of  the  pendulum  bob  of  a  clock  is
approximately  simple  harmonic  motion.

{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

{Harmonic  triad}  (Mus.),  the  chord  of  a  note  with  its  third
