Pitch Angle (engineering)
This page lists the standard US nomenclature used in the description of mechanical gear construction and function, together with definitions of the terms. The terminology was established by the American Gear Manufacturers Association (AGMA), under accreditation from the American National Standards Institute (ANSI). Addendum The addendum is the height by which a tooth of a gear projects beyond (outside for external, or inside for internal) the standard #Pitch circle, pitch circle or #Pitch line, pitch line; also, the radial distance between the pitch diameter and the outside diameter. Addendum angle Addendum angle in a bevel gear, is the angle between face cone and pitch cone. Addendum circle The addendum circle coincides with the tops of the teeth of a gear and is concentric with the standard (reference) pitch circle and radially distant from it by the amount of the addendum#In engineering, addendum. For external gears, the addendum circle lies on the outside cylinder wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch (music)
Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Perception Pitch and frequency Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Absolute Pitch
Absolute pitch (AP), often called perfect pitch, is a rare ability of a person to identify or re-create a given musical note without the benefit of a reference tone. AP may be demonstrated using linguistic labeling ("naming" a note), associating mental imagery with the note, or sensorimotor responses. For example, an AP possessor can accurately reproduce a heard tone on a musical instrument without "hunting" for the correct pitch. The frequency of AP in the general population is not known. A proportion of 1 in 10,000 is widely reported, but not supported by evidence; a 2019 review indicated a prevalence of at least 4% amongst music students. Generally, absolute pitch implies some or all of these abilities, achieved without a reference tone: * Identify by name individual pitches played on various instruments. * Name the key of a given piece of tonal music. * Identify and name all the tones of a given chord or other tonal mass. * Name the pitches of common everyday sounds such as ...

Pitch Pine
''Pinus rigida'', the pitch pine, is a small-to-medium-sized pine. It is native to eastern North America, primarily from central Maine south to Georgia and as far west as Kentucky. It is found in environments which other species would find unsuitable for growth, such as acidic, sandy, and low-nutrient soils. Description The pitch pine is irregular in shape, but grows to ). Branches are usually twisted, and it does a poor job at self-pruning. The needles are in fascicles (bundles) of three, about in length, and are stout (over broad) and often slightly twisted. The cones are long and oval, with prickles on the scales. Trunks are usually straight with a slight curve, covered in large, thick, irregular plates of bark. Pitch pine has an exceptionally high regenerative ability; if the main trunk is cut or damaged by fire, it can re-sprout using epicormic shoots. This is one of its many adaptations to fire, which also include a thick bark to protect the sensitive cambium layer from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch Class
In music, a pitch class (p.c. or pc) is a set of all pitches that are a whole number of octaves apart; for example, the pitch class C consists of the Cs in all octaves. "The pitch class C stands for all possible Cs, in whatever octave position." Important to musical set theory, a pitch class is "all pitches related to each other by octave, enharmonic equivalence, or both." Thus, using scientific pitch notation, the pitch class "C" is the set : = . Although there is no formal upper or lower limit to this sequence, only a few of these pitches are audible to humans. Pitch class is important because human pitch-perception is periodic: pitches belonging to the same pitch class are perceived as having a similar quality or color, a property called "octave equivalence". Psychologists refer to the quality of a pitch as its "chroma". A ''chroma'' is an attribute of pitches (as opposed to ''tone height''), just like hue is an attribute of color. A ''pitch class'' is a set of all pit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch Accent
A pitch-accent language, when spoken, has word accents in which one syllable in a word or morpheme is more prominent than the others, but the accentuated syllable is indicated by a contrasting pitch ( linguistic tone) rather than by loudness (or length), as in many languages, like English. Pitch-accent also contrasts with fully tonal languages like Vietnamese and Standard Chinese, in which each syllable can have an independent tone. Some have claimed that the term "pitch accent" is not coherently defined and that pitch-accent languages are just a sub-category of tonal languages in general. Languages that have been described as pitch-accent languages include: most dialects of Serbo-Croatian, Slovene, Baltic languages, Ancient Greek, Vedic Sanskrit, Tlingit, Turkish, Japanese, Norwegian, Swedish (but not in Finland), Western Basque,Hualde, J.I.

Pitch (gear)
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sales Pitch
As a selling technique, a sales presentation or sales pitch is a line of talk that attempts to persuade someone or something, with a planned sales presentation strategy of a product or service designed to initiate and close a sale of the product or service. A sales pitch is essentially designed to be either an introduction of a product or service to an audience who knows nothing about it, or a descriptive expansion of a product or service that an audience has already expressed interest in. Sales professionals prepare and give a sales pitch, which can be either formal or informal, and might be delivered in any number of ways. A sales pitch may be invited by an organisation looking to obtain supplies or services, for example in a commissioning context. Elements First impression The first visual and audible impression upon a market or client can appeal any of the five senses in order to initiate excellent chemistry between the buyer and seller. A way of luring in the potentia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch (resin)
Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, or plants. Various forms of pitch may also be called tar, bitumen, or asphalt. Pitch produced from plants is also known as resin. Some products made from plant resin are also known as rosin. Uses Pitch was traditionally used to help caulk the seams of wooden sailing vessels (see shipbuilding), and to coat earthenware vessels for the preservation of wine. Pitch may also be used to waterproof wooden containers and in the making of torches. Petroleum-derived pitch is black in colour, hence the adjectival phrase, "pitch-black". The viscoelastic properties of pitch make it well suited for the polishing of high-quality optical lenses and mirrors. In use, the pitch is formed into a lap or polishing surface, which is charged with iron oxide ( Jewelers' rouge) or cerium oxide. The surface to be polished is pressed into the pitch, then rubbed against the surface so formed. The ability ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch Weekly
''The Pitch'' is a free alternative newspaper distributed in the Kansas City Metropolitan Area, including Lawrence and Topeka, Kansas. While known for its investigative stories of the local government, it also covers local sports stories, restaurants, events, visual art, and concerts. It was started in July 1980 as the ''Penny Pitch'', which was a monthly handout at Penny Lane Record Shop in the Westport area of Kansas City.

Pitch (film)
''Pitch'' is a 1997 Canadian documentary created by Kenny Hotz and Spencer Rice, featuring themselves as two young filmmakers attending the Toronto International Film Festival to pitch a film concept to various celebrities. Their film idea, titled "The Dawn", concerns a Mafia don who goes for a hernia operation but gets a sex change instead. During the 1996 Toronto fest, they approach Roger Ebert, Norman Jewison (at a packed press conference), Eric Stoltz (leaving a limo), Al Pacino, and others without much success. On a roll, they leave Toronto for Hollywood, getting advice from Arthur Hiller and Neil Simon and finding an agent who expresses interest in their pitch. The film was shown at the 1997 Toronto Film Festival. The film features songs by the Toronto band Phono-Comb Phono-Comb was a Canadian instrumental/modern surf rock group that formed in 1993 in Toronto. History Phono-Comb first materialized when Shadowy Men on a Shadowy Planet played with Jad Fair when he wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
