  Disorders of pitch   (Site not responding. Last check: 2007-10-22)
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.
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.

 Pitch
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.
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.

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

 FAQ About Pitch Canker   (Site not responding. Last check: 2007-10-22)
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.
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.
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.

 Rules of Card Games: Setback / Pitch
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 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 paradoxical
Pitch perception is one of the many fascinating mysteries of hearing.
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.

 The Pitch Drop Experiment   (Site not responding. Last check: 2007-10-22)
Three years were allowed for the pitch to settle, and in 1930 the sealed stem was cut.

 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.
The just noticeable difference in pitch is conveniently expressed in cents, and the standard figure for the human ear is 5 cents.
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 Pitch Drop Experiment
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.
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.
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   (Site not responding. Last check: 2007-10-22)
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.
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.
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.

 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.
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.
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.

 Perfect pitch   (Site not responding. Last check: 2007-10-22)
Having absolute pitch means that I can hear a note and tell you that it's a G, or an E flat, or whatever.
They tend to identify pitch by having one or two reference pitches in their head (typically an open string on a violin, or something).
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.

 Absolute Pitch ear training software for learning perfect pitch
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.
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).
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.

 The Physics Classroom
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.
But pitch is not the only property of a sound wave detectable by the human ear.

 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.
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.
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.

 Absolute pitch and melody recognition   (Site not responding. Last check: 2007-10-22)
In each trial, participants were shown a short standard melody notated in the C major and heard a comparison melody played in the C major (untransposed) or in the A flat major or F sharp major (transposed).
The comparison melody was either exactly the same as the notated standard in relative pitch or had one tone shifted by one or two semitones.
The listeners having no absolute pitch exhibited equivalent performance regardless of whether or not the comparison melodies were transposed from the notated standard melodies.
