Cross-rhythm
In music, a cross-beat or cross-rhythm is a specific form of polyrhythm. The term ''cross rhythm '' was introduced in 1934 by the Musicology, musicologist Arthur Morris Jones (1889–1980). It refers to a situation where the rhythmic conflict found in polyrhythms is the basis of an entire musical piece. Etymology The term "cross rhythm" was introduced in 1934 by the Musicology, musicologist Arthur Morris Jones (1889–1980), who, with Klaus Wachsmann, took-up extended residence in Zambia and Uganda, respectively, as missionaries, educators, musicologists, and museologists. African music One main system African cross-rhythm is most prevalent within the greater Niger-Congo linguistic group, which dominates the continent south of the Sahara Desert. (Kubik, p. 58) Cross-rhythm was first identified as the basis of sub-Saharan rhythm by A.M. Jones. Later, the concept was more fully explained in the lectures of Ewe drumming, Ewe master drummer and scholar C.K. Ladzekpo, ...

Polyrhythm
Polyrhythm () is the simultaneous use of two or more rhythms that are not readily perceived as deriving from one another, or as simple manifestations of the same meter. The rhythmic layers may be the basis of an entire piece of music (cross-rhythm), or a momentary section. Polyrhythms can be distinguished from irrational rhythms, which can occur within the context of a single Part (music), part; polyrhythms require at least two rhythms to be played concurrently, one of which is typically an irrational rhythm. Concurrently in this context means within the same rhythmic cycle. The underlying pulse, whether explicit or implicit can be considered one of the concurrent rhythms. For example, the Clave (rhythm)#Son clave, son clave is poly-rhythmic because its 3 section suggests a different meter from the pulse of the entire pattern. In western art music In some European art music, polyrhythm periodically contradicts the prevailing meter. For example, in Wolfgang Amadeus Mozart, Moz ...

Ewe Drumming
Ewe drumming refers to the drumming Musical ensemble, ensembles of the Ewe people of Ghana, Togo, and Benin. The Ewe are known for their experience in drumming throughout West Africa. The sophisticated cross rhythms and polyrhythms in Ewe drumming are similar to those in Afro-Caribbean music and late jazz. The original purpose of Ewe drumming were sung or performed by warriors. Now the songs and performed to celebrate or for recreational use. For example, Agbadza was originally used as a warrior dance but is now used to celebrate events. Variation Ewe drumming is very diverse and is played in many slightly different ways. For example, an Ewe musician from Togo may play a piece or instrument slightly differently from the way a Ewe from Ghana does. The Fon people of Benin are another example of this variation. They construct their villages, towns, and cities on water, and because of this, they do not play the same upright drums other Ewe play. Instead, they place large gourds on wate ...

Ostinato
In music, an ostinato (; derived from the Italian word for ''stubborn'', compare English ''obstinate'') is a motif or phrase that persistently repeats in the same musical voice, frequently in the same pitch. Well-known ostinato-based pieces include classical compositions such as Ravel's ''Boléro'' and the '' Carol of the Bells'', and popular songs such as John Lennon’s “Mind Games” (1973), Donna Summer and Giorgio Moroder's " I Feel Love" (1977), Henry Mancini's theme from ''Peter Gunn'' (1959), The Who's " Baba O'Riley" (1971), The Verve's " Bitter Sweet Symphony" (1997), and Flo Rida's " Low" (2007). Both ''ostinatos'' and ''ostinati'' are accepted English plural forms, the latter reflecting the word's Italian etymology. The repeating idea may be a rhythmic pattern, part of a tune, or a complete melody in itself. Kamien, Roger (1258). ''Music: An Appreciation'', p. 611. . Strictly speaking, ostinati should have exact repetition, but in common usage, the term cover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiola
In music, hemiola (also hemiolia) is the ratio 3:2. The equivalent Latin term is sesquialtera. In rhythm, ''hemiola'' refers to three beats of equal value in the time normally occupied by two beats. In pitch, ''hemiola'' refers to the interval of a perfect fifth. Etymology The word ''hemiola'' comes from the Greek adjective ἡμιόλιος, ''hemiolios'', meaning "containing one and a half," "half as much again," "in the ratio of one and a half to one (3:2), as in musical sounds." The words "hemiola" and "sesquialtera" both signify the ratio 3:2, and in music were first used to describe relations of pitch. Dividing the string of a monochord in this ratio produces the interval of a perfect fifth. Beginning in the 15th century, both words were also used to describe rhythmic relationships, specifically the substitution (usually through the use of coloration—red notes in place of black ones, or black in place of "white", hollow noteheads) of three imperfect notes (divided into t ...

Arthur Morris Jones
Arthur Morris Jones (1889–1980), was an English missionary and musicologist who worked in Zambia during the early 20th century. Jones became a priest in 1923 and served as a curate in Kent before travelling to Northern Rhodesia (now Zambia) in 1929 with the Universities’ Mission to Central Africa. He was stationed at St Mark's School in Mapanza, a community in the Southern Province of present-day Zambia (called Rhodesia at the time). He is best known for his ethnomusicological work, particularly his two-volume '' Studies in African Music''. He made an important contribution to the literature with his work in African rhythmic structure. In 1934 he introduced the technical term ''cross-rhythm'': Formulae of movement, phrases or motifs are combined in that way, that their starting place, main accents and, or beat reference points "cross", that is, that they do not coincide. In ''Studies in African Music'' he says that "African children love to turn any physical movement in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycle (music)
In music, a cycle can be several things. Acoustically, it is one complete vibration, the base unit of Hertz being one cycle per second. Theoretically, an interval cycle is a collection of pitch classes created by a sequence of identical intervals. Cycles are also individual pieces of larger works, like the movements in a suite, symphony sonata, or string quartet. This can range from settings of the Mass or a song cycle to an opera cycle. Another cycle is the complete performance of an individual composer's work in one genre. Harmonic cycles—repeated sequences of a harmonic progression—are at the root of many musical genres, such as the twelve-bar blues. In compositions of this genre, the chord progression may be repeated indefinitely, with melodic and lyrical variation forming the musical interest. The form theme and variations is essentially of this type, but generally on a larger scale. Composition using a tone row is another example of a cycle of pitch material, although ...

Cross-beat Escapement
An escapement is a mechanical linkage in mechanical watches and clocks that gives impulses to the timekeeping element and periodically releases the gear train to move forward, advancing the clock's hands. The impulse action transfers energy to the clock's timekeeping element (usually a pendulum or balance wheel) to replace the energy lost to friction during its cycle and keep the timekeeper oscillating. The escapement is driven by force from a coiled spring or a suspended weight, transmitted through the timepiece's gear train. Each swing of the pendulum or balance wheel releases a tooth of the escapement's ''escape wheel'', allowing the clock's gear train to advance or "escape" by a fixed amount. This regular periodic advancement moves the clock's hands forward at a steady rate. At the same time, the tooth gives the timekeeping element a push, before another tooth catches on the escapement's pallet, returning the escapement to its "locked" state. The sudden stopping of the escape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyil
The balafon (pronounced , or, by analogy with ''xylophone'' etc., ) is a gourd-resonated xylophone, a type of struck idiophone. It is closely associated with the neighbouring Mandé, Bwaba Bobo, Senoufo and Gur peoples of West Africa, particularly the Guinean branch of the Mandinka ethnic group, but is now found across West Africa from Guinea, Burkina Faso, Mali. Its common name, ''balafon'', is likely a European coinage combining its Mandinka name ''bala'' () with the word ''fôn'' () 'to speak' or the Greek root ''phono''. History Believed to have been developed independently of the Southern African and South American instrument now called the marimba, oral histories of the balafon date it to at least the rise of the Mali Empire in the 12th century CE. Balafon is a Manding name, but variations exist across West Africa, including the ''balangi'' in Sierra Leone and the gyil of the Dagara, Lobi and Gurunsi from Ghana, Burkina Faso and Ivory Coast.

Xylophone
The xylophone (; ) is a musical instrument in the percussion family that consists of wooden bars struck by mallets. Each bar is an idiophone tuned to a pitch of a musical scale, whether pentatonic or heptatonic in the case of many African and Asian instruments, diatonic in many western children's instruments, or chromatic for orchestral use. The term ''xylophone'' may be used generally, to include all such instruments such as the marimba, balafon and even the semantron. However, in the orchestra, the term ''xylophone'' refers specifically to a chromatic instrument of somewhat higher pitch range and drier timbre than the marimba, and these two instruments should not be confused. A person who plays the xylophone is known as a ''xylophonist'' or simply a ''xylophone player''. The term is also popularly used to refer to similar instruments of the lithophone and metallophone types. For example, the Pixiphone and many similar toys described by the makers as xylophones have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
