 Aircraft Pitch Motion
The pitching motion is being caused by the deflection of the elevator of this aircraft.
The pitch axis is perpendicular to the aircraft centerline and lies in the plane of the wings.
A pitch motion is an up or down movement of the nose of the aircraft as shown in the animation.

 FAQ About Pitch Canker
Pitch Canker is a disease, which causes die-back of individual branches (figure 1), leading to a general decline in tree health, and, in some cases, premature death.
In cases where the incidence of pitch canker is isolated, the timely removal of diseased branch tips may be effective in slowing the spread of the disease.
Many of these insects are known to transmit the pitch canker fungus to healthy trees and are considered to be the primary means by which new infections are established.

 Pitch Diameter
In a bevel or hypoid gear, the pitch diameter is understood to be at the outer ends of the teeth unless otherwise specified.
A gear does not have an operating pitch diameter until it is meshed with a mating gear.
In parallel shaft gears the pitch diameters can be determined directly from the centre distance and the numbers of teeth by proportionality.

 Disorders of pitch
To lower the pitch of the voice, a procedure called a thyroplasty can be performed in which a small vertical strip of cartilage is removed from one or both sides of the thyroid cartilage in the neck.
Disorders in which the pitch is too low most often result from anabolic hormones or hormonal imbalance (such as adrenocortical syndrome) and are most often seen among females.
The pitch of the voice is determined by four main factors.

 Pitch
The pitch ascribed to a complex tone or sound may not necessarily correspond to a frequency that is physically present in the sound.
In summary, Schouten has stated, "The pitch ascribed to a complex sound is the pitch of that component to which the attention, either by virtue of its loudness or of its contrast with former sounds is strongest drawn.
The sense of pitch depends on the intensity of the tone, as shown in the graph; below 1000 Hz, pitch tends to drop with increasing loudness, and above 1000 Hz, tends to rise.

 Rules of Card Games: Setback / Pitch
The version of Pitch in which the five is an additional scoring trump worth 5 points (making 9 points in all) is now described on the Pedro page, along with Double Pedro or Cinch, in which the other five of the same colour is also a trump scoring 5 (for a total of 14 points).
Pitch is a North American game, derived from the old English game of All Fours (which was also known in America as Seven Up or Old Sledge).
There is also "Dirty Pitch" in which the point for Low goes to the side that wins the Two rather than holding it, and "Reverse Pitch" in which the rank of the trumps is reversed (two high and ace low).

The pitch of a harmonic tone is defined to be its fundamental frequency, which is the frequency of the pure tone which has the same pitch.
As confusing as pitch is for a single tone, the difficulties are compounded with multiple tones, multiple voices or instruments.

 Sequoia Pitch Moth Management Guidelines--UC IPM
Pitch canker can infect pine tissue of any age, including young branches and terminal shoots the diameter of a pencil; bark beetles and sequoia pitch moth primarily attack the main trunk, though sometimes large limbs several inches in diameter can also be attacked.
Bark beetle pitch tubes are usually less than 1/2 inch in diameter and typically have a distinct round hole in the center made by an adult beetle.
Yellow and red dying and dead branches scattered throughout the tree are a characteristic symptom of pitch canker, eventually followed by death of the entire pine tree; branches rarely die from sequoia pitch moth.

 Pitch
The pitch perception of the human ear is understood to operate basically by the place theory, with some sharpening mechanism necessary to explain the remarkably high resolution of human pitch perception.
Although for most practical purposes, the pitch of a sound can be said to be simply a measure of its frequency, there are circumstances in which a constant frequency sound can be perceived to be changing in pitch.
The just noticeable difference in pitch is conveniently expressed in cents, and the standard figure for the human ear is 5 cents.

 The Pitch Drop Experiment
Video clip showing what pitch is like at room temperature and what happens when you hit it with a hammer.
Three years were allowed for the pitch to settle, and in 1930 the sealed stem was cut.
From that date on the pitch has slowly dripped out of the funnel - so slowly that now, 72 years later, the eighth drop is only just about to fall.

 The Pitch Drop Experiment
As indicated previously the pitch drop experiment is not kept in a temperature controlled environment and estimations of the actual temperature changes from 19 27 to the present time involve a lot of guesswork.
This was done by measuring the mass of water needed to fill the beaker, into which the pitch drops fell, up to a convenient mark, and then (by measuring the dimensions of the beaker) determining the volume of water required to fill the beaker (if empty of pitch) up to the same mark.
Allowing the pitch drop result to be as low as 1x10^8 Pa s due to the possible effect of the pendant drop brings model VII into agreement with the experimental result.

 Huggins Pitch: A dichotic pitch
Huggins Pitch is produced such that the three pitches are played in succession (400 to 440 Hz first, 500 to 550 second, and 600 to 660 third), each for one second following a section of noise without a dichotic pitch.
That is, in the demonstration the dichotic Huggins pitch should sound about the same (although fainter) than that produced by narrow bands of noise with bandwidths of 400 to 440 Hz, 500 to 550 Hz, or 600 to 660 Hz.
A faint pitch is heard which mimics that one would hear if they only listen to the sound of the region of the interaural phase shift.

 Perfect pitch
When they hear a pitch, they can compare it to the reference pitch, see what the interval between the two pitches is, and calculate the pitch that they heard from that.
They tend to identify pitch by having one or two reference pitches in their head (typically an open string on a violin, or something).
Having absolute pitch means that I can hear a note and tell you that it's a G, or an E flat, or whatever.

 Absolute Pitch ear training software for learning perfect pitch
Having absolute pitch makes it easier for a composer or performer, especially of atonal music, to retain and hear complex melodies and harmonies in his or her head (Schoenberg mentions his ability in a letter; Boulez is well known for it).
Musicians with extremely good relative pitch can give results indistinguishable from those having absolute pitch, but they are always at a disadvantage in having to hear a reference tone, such as Middle A, first.
For any singer, it obviates the use of a reference pitch, and ensures that performing without instrumental accompaniment, such as in a barbershop quartet, doesn't risk a gradual sliding out of tune during a piece.

 ASA 148th Meeting Lay Language Papers -Perfect Pitch in Tone Language Speakers Carries Over to Music
Absolute pitch, popularly known as "perfect pitch," is the ability to name or produce a musical note of particular pitch without benefit of a reference note.
In this, the first large-scale study in which the prevalence of absolute pitch in normal populations was compared using a direct test, we examined the prevalence of absolute pitch in two groups of music students.
On this line of reasoning, absolute pitch for music might then be acquired by tone language speakers in the same way as they would acquire the pitches of a second tone language.

 University of California Absolute Pitch Study
Absolute Pitch, commonly referred to as Perfect Pitch, is an intriguing behavioral trait involved in music perception and is defined as the ability to recognize the pitch of a musical tone without an external reference pitch.
From our initial testing of a mixed population of self-reported absolute pitch and non-absolute pitch musicians, we were able to determine the distribution and mean scores on both the pure tone and piano tone tests.
A large survey was conducted to assess the role of musical training in the development of Perfect Pitch and to evaluate whether this trait aggregates in families.

 The Physics Classroom
But pitch is not the only property of a sound wave detectable by the human ear.
A high pitch sound corresponds to a high frequency and a low pitch sound corresponds to a low frequency.
Because sound waves are longitudinal waves which produce high- and low-pressure disturbances of the particles of a medium at a given frequency, the ear has an ability to detect such frequencies and associate them with the pitch of the sound.

 Slow-Pitch Softball RULES
The pitch, delivered with an underhand motion, must have a perceptible arc and reach a height of at least 6 feet from the ground, while not exceeding a maximum of 12 feet.
A pitch delivered legally with the proper arc requirement that crosses the plate within the strike zone will be called a strike.
If the catcher in any way obstructs the umpire's view, the pitch shall be declared a ball.
