Rhythms
Rhythm (from Greek , ''rhythmos'', "any regular recurring motion, symmetry") generally means a " movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions". This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or hours, or, at the most extreme, even over many years. The Oxford English Dictionary defines rhythm as ''"The measured flow of words or phrases in verse, forming various patterns of sound as determined by the relation of long and short or stressed and unstressed syllables in a metrical foot or line; an instance of this"''. Rhythm is related to and distinguished from pulse, meter, and beats: In the performance arts, rhythm is the timing of events on a human scale; of musical sounds and silences that occur over ...

Music
Music is the arrangement of sound to create some combination of Musical form, form, harmony, melody, rhythm, or otherwise Musical expression, expressive content. Music is generally agreed to be a cultural universal that is present in all human societies. Definitions of music vary widely in substance and approach. While scholars agree that music is defined by a small number of elements of music, specific elements, there is no consensus as to what these necessary elements are. Music is often characterized as a highly versatile medium for expressing human creativity. Diverse activities are involved in the creation of music, and are often divided into categories of musical composition, composition, musical improvisation, improvisation, and performance. Music may be performed using a wide variety of musical instruments, including the human voice. It can also be composed, sequenced, or otherwise produced to be indirectly played mechanically or electronically, such as via a music box ...

Traditional Indonesian Instruments02
A tradition is a system of beliefs or behaviors (folk custom) passed down within a group of people or society with symbolic meaning or special significance with origins in the past. A component of cultural expressions and folklore, common examples include holidays or impractical but socially meaningful clothes (like lawyers' wigs or military officers' spurs), but the idea has also been applied to social norms and behaviors such as greetings, etc. Traditions can persist and evolve for thousands of years— the word ''tradition'' itself derives from the Latin word ''tradere'' literally meaning to transmit, to hand over, to give for safekeeping. While it is reportedly assumed that traditions have an ancient history, many traditions have been invented on purpose, whether it be political or cultural, over short periods of time. Various academic disciplines also use the word in a variety of ways. The phrase "according to tradition" or "by tradition" usually means that what follows i ...

Hip Hop Music
Hip-hop or hip hop (originally disco rap) is a popular music Music genre, genre that emerged in the early 1970s from the African Americans, African-American community of New York City. The style is characterized by its synthesis of a wide range of musical techniques. Hip-hop includes rapping often enough that the terms can be used synonymously. However, "hip-hop" more properly denotes an entire hip-hop culture, subculture. Other key markers of the genre are the disc jockey, turntablism, scratching, beatboxing, and hip hop production, instrumental tracks. Cultural interchange has always been central to the hip-hop genre. It simultaneously borrows from its social environment while commenting on it. The hip-hop genre and culture emerged from block parties in ethnic minority neighborhoods of New York City, particularly The Bronx, Bronx. DJs began expanding the instrumental Break (music), breaks of popular records when they noticed how excited it would make the crowds. The extend ...

Ray Jackendoff
Ray Jackendoff (born January 23, 1945) is an American linguist. He is professor of philosophy, Seth Merrin Chair in the Humanities and, with Daniel Dennett, co-director of the Center for Cognitive Studies at Tufts University. He has always straddled the boundary between generative linguistics and cognitive linguistics, committed to both the existence of an innate universal grammar (an important thesis of generative linguistics) and to giving an account of language that is consistent with the current understanding of the human mind and cognition (the main purpose of cognitive linguistics). Jackendoff's research deals with the semantics of natural language, its bearing on the formal structure of cognition, and its lexical and syntactic expression. He has conducted extensive research on the relationship between conscious awareness and the computational theory of mind, on syntactic theory, and, with Fred Lerdahl, on musical cognition, culminating in their generative theory of t ...

Entrainment (biomusicology)
Entrainment in the biomusicological sense refers to the synchronization (e.g., foot tapping) of organisms to an external perceived rhythm such as human music and dance. Humans are the only species for which all individuals experience entrainment, although there are documented examples of entrained nonhuman individuals. Beat induction Beat induction is the process in which a regular isochronous pulse is activated while one listens to music (i.e., the beat to which one would tap one's foot). It was thought that the cognitive mechanism that allows us to infer a beat from a sound pattern, and to synchronize or dance to it, was uniquely human. No primate tested so far—with exception of the human species—can dance or collaboratively clap to the beat of the music. Humans know when to start, when to stop, when to speed up or to slow down, in synchronizing with their fellow dancers or musicians. Although primates do not appear to display beat induction, some parrots do. The most famo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the Heredity, heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with selective breeding, artificial selection, which is intentional, whereas natural selection is not. Genetic diversity, Variation of traits, both Genotype, genotypic and phenotypic, exists within all populations of organisms. However, some traits are more likely to facilitate survival and reproductive success. Thus, these traits are passed the next generation. These traits can also become more Allele frequency, common within a population if the environment that favours these traits remains fixed. If new traits become more favoured due to changes in a specific Ecological niche, niche, microevolution occurs. If new traits become more favoured due to changes in the ...

Hominid
The Hominidae (), whose members are known as the great apes or hominids (), are a taxonomic family of primates that includes eight extant species in four genera: '' Pongo'' (the Bornean, Sumatran and Tapanuli orangutan); '' Gorilla'' (the eastern and western gorilla); '' Pan'' (the chimpanzee and the bonobo); and ''Homo'', of which only modern humans (''Homo sapiens'') remain. Numerous revisions in classifying the great apes have caused the use of the term ''hominid'' to change over time. The original meaning of "hominid" referred only to humans (''Homo'') and their closest extinct relatives. However, by the 1990s humans and other apes were considered to be "hominids". The earlier restrictive meaning has now been largely assumed by the term ''hominin'', which comprises all members of the human clade after the split from the chimpanzees (''Pan''). The current meaning of "hominid" includes all the great apes including humans. Usage still varies, however, and some scientis ...

Drum Pattern
A drum beat or drum pattern is a rhythmic pattern, or repeated rhythm establishing the meter and groove through the pulse and subdivision, played on drum kits and other percussion instruments. As such a "beat" consists of multiple drum strokes occurring over multiple musical beats while the term "drum beat" may also refer to a single drum stroke which may occupy more or less time than the current pulse. Many drum beats define or are characteristic of specific music genres. Many basic drum beats establish the pulse through alternating bass (on the on-beats) and snare drums (on the off-beats) strokes while establishing the subdivision on the ride cymbal (thus its name) or hi-hat: This establishes a quarter note pulse in (quad) duple time: each measure is formed from (two groups of) two quarter note pulses, each pulse divided into two eighth notes. This establishes a quarter note pulse in triple time: each measure is formed from three quarter note pulses, each divided int ...

Duple Meter
Duple metre (or Am. duple meter, also known as duple time) is a musical metre characterized by a ''primary'' division of 2 beats to the bar, usually indicated by 2 and multiples (simple) or 6 and multiples ( compound) in the upper figure of the time signature, with ( cut time), , and (at a fast tempo) being the most common examples. Shown below are a simple and a compound duple drum pattern. : \new Staff : \new Staff Though the upper number ''must be'' divisible by 2, the mere fact that 2 evenly divides the upper figure does not in and of itself indicate a duple metre; it is only a prerequisite. The most common time signature in rock, blues, country, funk, and pop is . Although jazz writing has become more adventurous since Dave Brubeck's ''Time Out'', the majority of jazz and jazz standards are still in " common time" (). Duple time is common in many styles including the polka, well known for its obvious "oom-pah" duple feel. Compare to the waltz. Quadruple me ...
