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 a ...

Musical Note
In music, a note is the representation of a musical sound. Notes can represent the pitch and duration of a sound in musical notation. A note can also represent a pitch class. Notes are the building blocks of much written music: discretizations of musical phenomena that facilitate performance, comprehension, and analysis. The term ''note'' can be used in both generic and specific senses: one might say either "the piece ' Happy Birthday to You' begins with two notes having the same pitch", or "the piece begins with two repetitions of the same note". In the former case, one uses ''note'' to refer to a specific musical event; in the latter, one uses the term to refer to a class of events sharing the same pitch. (See also: Key signature names and translations.) Two notes with fundamental frequencies in a ratio equal to any integer power of two (e.g., half, twice, or four times) are perceived as very similar. Because of that, all notes with these kinds of relations can be grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musical Scale
In music theory, a scale is any set of musical notes ordered by fundamental frequency or pitch. A scale ordered by increasing pitch is an ascending scale, and a scale ordered by decreasing pitch is a descending scale. Often, especially in the context of the common practice period, most or all of the melody and harmony of a musical work is built using the notes of a single scale, which can be conveniently represented on a staff with a standard key signature. Due to the principle of octave equivalence, scales are generally considered to span a single octave, with higher or lower octaves simply repeating the pattern. A musical scale represents a division of the octave space into a certain number of scale steps, a scale step being the recognizable distance (or interval) between two successive notes of the scale. However, there is no need for scale steps to be equal within any scale and, particularly as demonstrated by microtonal music, there is no limit to how many notes can be ...

Optic Nerve Hypoplasia
Optic nerve hypoplasia (ONH) is a medical condition arising from the underdevelopment of the optic nerve(s). This condition is the most common congenital optic nerve anomaly. The optic disc appears abnormally small, because not all the optic nerve axons have developed properly.Sadun, Alfredo A., and Michelle Y. Wang. ''Handbook of Clinical Neurology''. p. 37. In press. It is often associated with endocrinopathies (hormone deficiencies), developmental delay, and brain malformations. The optic nerve, which is responsible for transmitting visual signals from the retina to the brain, has approximately 1.2 million nerve fibers in the average person. In those diagnosed with ONH, however, there are noticeably fewer nerves. Symptoms ONH may be found in isolation or in conjunction with myriad functional and anatomic abnormalities of the central nervous system. Nearly 80% of those affected with ONH will experience hypothalamic dysfunction and/or impaired development of the brain, regardless ...

Human Group Differences
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mambila Language
Mambila is a dialect chain stretching across Nigeria and Cameroon. It is one of the Mambiloid languages, a branch of Benue–Congo. Notable dialects are Barup, Bang, Dorofi, Gembu, Hainari, Kabri, Mayo Ndaga, Mbamnga, Tamien, Warwar (in Nigeria); Sunu Torbi (Torbi), Ju Naare (Gembu), and in Cameroon, Ju Ba and Langa. Mambila goes by numerous names, which, besides the dialectical names, include Bea, Ble, Juli, Lagubi, Nor, Nor Tagbo, Tongbo, and the spellings Mabila, Mambere, Mambilla. Tep is generally considered a dialect by those in Tep and by speakers of other varieties of Mambila, but though Tep speakers are ethnically Mambila, their speech is not intelligible to other varieties. In terms of linguistic classification it may be more accurate to call it a different Mambiloid The twelve Mambiloid languages are languages spoken by the Mambila and related peoples mostly in eastern Nigeria and in Cameroon. In Nigeria the largest group is Mambila (there is also a small Mambila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yoruba Language
Yoruba (, ; Yor. '; Ajami: ) is a language spoken in West Africa, primarily in Southwestern and Central Nigeria. It is spoken by the ethnic Yoruba people. The number of Yoruba speakers is roughly 50 million, plus about 2 million second-language speakers. As a pluricentric language, it is primarily spoken in a dialectal area spanning Nigeria and Benin with smaller migrated communities in Côte d'Ivoire, Sierra Leone and The Gambia. Yoruba vocabulary is also used in the Afro-Brazilian religion known as Candomblé, in the Caribbean religion of Santería in the form of the liturgical Lucumí language and various Afro-American religions of North America. Practitioners of these religions in the Americas no longer speak or understand the Yorùbá language, rather they use remnants of Yorùbá language for singing songs that for them are shrouded in mystery. Usage of a lexicon of Yorùbá words and short phrases during ritual is also common, but they have gone through changes d ... [...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.

Sino-Tibetan Languages
Sino-Tibetan, also cited as Trans-Himalayan in a few sources, is a family of more than 400 languages, second only to Indo-European in number of native speakers. The vast majority of these are the 1.3 billion native speakers of Chinese languages. Other Sino-Tibetan languages with large numbers of speakers include Burmese (33 million) and the Tibetic languages (6 million). Other languages of the family are spoken in the Himalayas, the Southeast Asian Massif, and the eastern edge of the Tibetan Plateau. Most of these have small speech communities in remote mountain areas, and as such are poorly documented. Several low-level subgroups have been securely reconstructed, but reconstruction of a proto-language for the family as a whole is still at an early stage, so the higher-level structure of Sino-Tibetan remains unclear. Although the family is traditionally presented as divided into Sinitic (i.e. Chinese) and Tibeto-Burman branches, a common origin of the non-Sinitic languages has n ...

Southern Min
Southern Min (), Minnan ( Mandarin pronunciation: ) or Banlam (), is a group of linguistically similar and historically related Sinitic languages that form a branch of Min Chinese spoken in Fujian (especially the Minnan region), most of Taiwan (many citizens are descendants of settlers from Fujian), Eastern Guangdong, Hainan, and Southern Zhejiang. The Minnan dialects are also spoken by descendants of emigrants from these areas in diaspora, most notably the Philippines, Indonesia, Malaysia, Singapore, San Francisco, Los Angeles and New York City. It is the most populous branch of Min Chinese, spoken by an estimated 48 million people in c. 2017–2018. In common parlance and in the narrower sense, Southern Min refers to the Quanzhang or Hokkien-Taiwanese variety of Southern Min originating from Southern Fujian in Mainland China. This is spoken mainly in Fujian, Taiwan, as well as certain parts of Southeast Asia. The Quanzhang variety is often called simply "Minnan Proper". It ...

Cantonese
Cantonese ( zh, t=廣東話, s=广东话, first=t, cy=Gwóngdūng wá) is a language within the Chinese (Sinitic) branch of the Sino-Tibetan languages originating from the city of Guangzhou (historically known as Canton) and its surrounding area in Southeastern China. It is the traditional prestige variety of the Yue Chinese dialect group, which has over 80 million native speakers. While the term ''Cantonese'' specifically refers to the prestige variety, it is often used to refer to the entire Yue subgroup of Chinese, including related but largely mutually unintelligible languages and dialects such as Taishanese. Cantonese is viewed as a vital and inseparable part of the cultural identity for its native speakers across large swaths of Southeastern China, Hong Kong and Macau, as well as in overseas communities. In mainland China, it is the '' lingua franca'' of the province of Guangdong (being the majority language of the Pearl River Delta) and neighbouring areas such as Gu ...

Standard Mandarin
Standard Chinese ()—in linguistics Standard Northern Mandarin or Standard Beijing Mandarin, in common speech simply Mandarin, better qualified as Standard Mandarin, Modern Standard Mandarin or Standard Mandarin Chinese—is a modern standardized form of Mandarin Chinese that was first developed during the Republican Era (1912‒1949). It is designated as the official language of mainland China and a major language in the United Nations, Singapore, and Taiwan. It is largely based on the Beijing dialect. Standard Chinese is a pluricentric language with local standards in mainland China, Taiwan and Singapore that mainly differ in their lexicon. Hong Kong written Chinese, used for formal written communication in Hong Kong and Macau, is a form of Standard Chinese that is read aloud with the Cantonese reading of characters. Like other Sinitic languages, Standard Chinese is a tonal language with topic-prominent organization and subject–verb–object (SVO) word order. C ...
