The point where a declivity begins; hence, the declivity itself; a descending slope; the degree or rate of descent or slope; slant; as, a steep pitch in the road; the pitch of a roof. 7. (Mus.) The relative acuteness or gravity of a tone, determined by the number of vibrations which produce it; the place of any tone upon a scale of high and low. 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. 8. (Mining) The limit of ground set to a miner who receives a share of the ore taken out. 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 holes in boiler plates. 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 30[deg], of 45[deg], 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 pipe, a wind instrument used by choristers in regulating the pitch of a tune.
