   7. mus. the relative acuteness or gravity of a tone,
      determined by the number of vibrations which produce it;

   note: musical tones with reference to absolute pitch, are
         named after the first seven letters of the alphabet;
         with reference to relative pitch, in a series of tones
         called the scale, they are called one, two, three,
         four, five, six, seven, eight. eight is also one of a
         new scale an octave higher, as one is eight of a scale
         an octave lower.

   9. mech.
      a the distance from center to center of any two adjacent
          teeth of gearing, measured on the pitch line; --
          called also circular pitch.
      b the length, measured along the axis, of a complete
          turn of the thread of a screw, or of the helical lines
          of the blades of a screw propeller.
      c the distance between the centers of holes, as of rivet

   10. elec. the distance between symmetrically arranged or
       corresponding parts of an armature, measured along a
       line, called the pitch line, drawn around its length.
       sometimes half of this distance is called the pitch.

   concert pitch mus., the standard of pitch used by
      orchestras, as in concerts, etc.

   diametral pitch gearing, the distance which bears the
      same relation to the pitch proper, or circular pitch, that
      the diameter of a circle bears to its circumference; it is
      sometimes described by the number expressing the quotient
      obtained by dividing the number of teeth in a wheel by the
      diameter of its pitch circle in inches; as, 4 pitch, 8
      pitch, etc.

   pitch chain, a chain, as one made of metallic plates,
      adapted for working with a sprocket wheel.

   pitch line, or pitch circle gearing, an ideal line, in
      a toothed gear or rack, bearing such a relation to a
      corresponding line in another gear, with which the former
      works, that the two lines will have a common velocity as
      in rolling contact; it usually cuts the teeth at about the
      middle of their height, and, in a circular gear, is a
      circle concentric with the axis of the gear; the line, or
      circle, on which the pitch of teeth is measured.

   pitch of a roof arch., the inclination or slope of the
      sides expressed by the height in parts of the span; as,
      one half pitch; whole pitch; or by the height in parts of
      the half span, especially among engineers; or by degrees,
      as a pitch of 30deg, of 45deg, etc.; or by the rise
      and run, that is, the ratio of the height to the half
      span; as, a pitch of six rise to ten run. equilateral
      pitch is where the two sloping sides with the span form an
      equilateral triangle.

   pitch of a plane carp., the slant of the cutting iron.

   pitch of poles elec., the distance between a pair of
      poles of opposite sign.

   pitch pipe, a wind instrument used by choristers in
      regulating the pitch of a tune.
