The second definition of pitch refers to the field on which sports are played - including cricket. This is not quite right - the cricket pitch refers only to the (approx) 20 metre strip of rolled turf/astro turf/concrete on which the bowler bowls and batter bats. The rest of the field is referred to, generally, as a field or a ground, i.e. Melbourne Cricket Ground or Sydney Cricket Ground. Crom 188.8.131.52 21:57, 6 October 2010 (UTC)
Unknown etymology 3
Etymology 3 is probably related to etymology 2: "the angle at which an object sits": angle > angular frequency of a rotating object > frequency of a sinusoidal wave > frequency of a sound wave
Under Etymology 2, aren't noun definitions #5, #22, #23, and #24 really just saying the same thing?
