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 ...

Cross-beat
In music, a cross-beat or cross-rhythm is a specific form of polyrhythm. The term ''cross rhythm '' was introduced in 1934 by the musicologist Arthur Morris Jones (1889–1980). It refers to when 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 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 master drummer and scholar C.K. Ladzekpo, and in the writings of David Locke. Jones observes ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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; 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 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 Mozart's opera '' Don Giovanni'', two orchestras are heard playing ...

Perfect Fifth
In music theory, a perfect fifth is the musical interval corresponding to a pair of pitches with a frequency ratio of 3:2, or very nearly so. In classical music from Western culture, a fifth is the interval from the first to the last of five consecutive notes in a diatonic scale. The perfect fifth (often abbreviated P5) spans seven semitones, while the diminished fifth spans six and the augmented fifth spans eight semitones. For example, the interval from C to G is a perfect fifth, as the note G lies seven semitones above C. The perfect fifth may be derived from the harmonic series as the interval between the second and third harmonics. In a diatonic scale, the dominant note is a perfect fifth above the tonic note. The perfect fifth is more consonant, or stable, than any other interval except the unison and the octave. It occurs above the root of all major and minor chords (triads) and their extensions. Until the late 19th century, it was often referred to by one of its Gr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Color (medieval Music)
In medieval music theory, the terms color and coloration are used in four distinct senses, two of which relate to the notation and structuring of note durations, the third to florid ornamentation, and the fourth to the quality of chromatic music. Coloration (mensural notation device) As a notation device in mensural notation, the 14th–16th century system of notating musical meters and rhythms, ''coloration'' refers to the technique of marking notes as having a change in durational value—most commonly a reduction to two thirds of their normal value. It is indicated by literally coloring the note-heads in the written music differently than their normal appearance. In the 14th and early 15th century, colored notes were typically marked in red while normal notes were black; in the 16th century, the same effect was achieved by filling the note-heads in black while normal notes were hollow. Sequences of colored notes can be used to notate triplet rhythms or hemiola effects. Color ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ostinato
In music, an ostinato (; derived from 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 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), and The Verve's " Bitter Sweet Symphony" (1997). 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 covers repetition with variation and development, such as the alteration ...

Mensural Notation
Mensural notation is the musical notation system used for European vocal polyphonic music from the later part of the 13th century until about 1600. The term "mensural" refers to the ability of this system to describe precisely measured rhythmic durations in terms of numerical proportions between note values. Its modern name is inspired by the terminology of medieval theorists, who used terms like ''musica mensurata'' ("measured music") or ''cantus mensurabilis'' ("measurable song") to refer to the rhythmically defined polyphonic music of their age, as opposed to ''musica plana'' or ''musica choralis'', i.e., Gregorian plainchant. Mensural notation was employed principally for compositions in the tradition of vocal polyphony, whereas plainchant retained its own, older system of neume notation throughout the period. Besides these, some purely instrumental music could be written in various forms of instrument-specific tablature notation. Mensural notation grew out of an earlier, ...

George Grove
Sir George Grove (13 August 182028 May 1900) was an English engineer and writer on music, known as the founding editor of ''Grove's Dictionary of Music and Musicians''. Grove was trained as a civil engineer, and successful in that profession, but his love of music drew him into musical administration. When responsible for the regular orchestral concerts at the Crystal Palace, he wrote a series of programme notes from which eventually grew his musical dictionary. His interest in the music of Franz Schubert, which was neglected in England at that point in the nineteenth century, led him and his friend Arthur Sullivan to go to Vienna in search of undiscovered Schubert manuscripts. Their researches led to their discovery of the lost score of Schubert's ''Rosamunde'' music, several of his symphonies and other music in 1867, leading to a revival of interest in Schubert's work. Grove was the first director of the Royal College of Music, from its foundation in 1883 until his retireme ...

Rhythmic Cell
The 1957 ''Encyclopédie Larousse''quoted in Nattiez, Jean-Jacques (1990). ''Music and Discourse: Toward a Semiology of Music'' (''Musicologie générale et sémiologue'', 1987). Translated by Carolyn Abbate (1990). . defines a cell in music as a "small rhythmic and melodic design that can be isolated, or can make up one part of a thematic context". The cell may be distinguished from the figure or motif: the 1958 ''Encyclopédie Fasquelle'' defines a cell as "the smallest indivisible unit", unlike the motif, which may be divisible into more than one cell. "A cell can be developed, independent of its context, as a melodic fragment, it can be used as a developmental motif. It can be the source for the whole structure of the work; in that case it is called a generative cell." A rhythmic cell is a cell without melodic connotations. It may be entirely percussive or applied to different melodic segments. History The term "cell" (German: ''Keim'') derives from organic music theorists ...
