Constant Structure
In jazz, a constant structure is a chord progression consisting of three or more chords of the same type or quality.Rawlins, Robert (2005). ''Jazzology: The Encyclopedia of Jazz Theory for All Musicians'', p.131. . Popularized by pianists Bill Evans and Herbie Hancock, the combination of functional and nonfunctional chords provides cohesiveness while producing a free and shifting tonal center. For example, the progression Fmaj7–Amaj7–Dmaj7–Gmaj7–C13sus4 contains four major seventh chords (and one thirteenth chord), none of which are diatonic to the key of F major except the first. In contrast, the vi–ii–V–I or circle progression from classical theory contains four chords of two or three different qualities: major, minor, and possibly a dominant seventh chord; all of which, however, are diatonic to the key. Thus diversity is achieved within a stable and fixed tonal center. See also *Parallel harmony *Side-slipping In jazz improvisation, outside playing descri ...

Jazz
Jazz is a music genre that originated in the African-American communities of New Orleans, Louisiana in the late 19th and early 20th centuries, with its roots in blues and ragtime. Since the 1920s Jazz Age, it has been recognized as a major form of musical expression in traditional and popular music. Jazz is characterized by swing and blue notes, complex chords, call and response vocals, polyrhythms and improvisation. Jazz has roots in European harmony and African rhythmic rituals. As jazz spread around the world, it drew on national, regional, and local musical cultures, which gave rise to different styles. New Orleans jazz began in the early 1910s, combining earlier brass band marches, French quadrilles, biguine, ragtime and blues with collective polyphonic improvisation. But jazz did not begin as a single musical tradition in New Orleans or elsewhere. In the 1930s, arranged dance-oriented swing big bands, Kansas City jazz (a hard-swinging, bluesy, improvisationa ...

Diatonic And Chromatic
Diatonic and chromatic are terms in music theory that are most often used to characterize scales, and are also applied to musical instruments, intervals, chords, notes, musical styles, and kinds of harmony. They are very often used as a pair, especially when applied to contrasting features of the common practice music of the period 1600–1900. These terms may mean different things in different contexts. Very often, ''diatonic'' refers to musical elements derived from the modes and transpositions of the "white note scale" C–D–E–F–G–A–B. In some usages it includes all forms of heptatonic scale that are in common use in Western music (the major, and all forms of the minor). ''Chromatic'' most often refers to structures derived from the twelve-note chromatic scale, which consists of all semitones. Historically, however, it had other senses, referring in Ancient Greek music theory to a particular tuning of the tetrachord, and to a rhythmic notational convention in me ...

Side-slipping
In jazz improvisation, outside playing describes an approach where one plays over a scale, mode or chord that is harmonically distant from the given chord. There are several common techniques to playing outside, that include side-stepping or side-slipping, superimposition of Coltrane changes, and polytonality. Side-slipping The term side-slipping or side-stepping has been used to describe several similar yet distinct methods of playing outside. In one version, one plays only the five "'wrong'" non-scale notes for the given chord Chord may refer to: * Chord (music), an aggregate of musical pitches sounded simultaneously ** Guitar chord a chord played on a guitar, which has a particular tuning * Chord (geometry), a line segment joining two points on a curve * Chord ( ... and none of the seven scale or three to four chord tones, given that there are twelve notes in the equal tempered scale and heptatonic scales are generally used. Another technique described as sides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parallel Harmony
In music, parallel harmony, also known as harmonic parallelism, harmonic planing or parallel voice leading, is the parallel movement of two or more melodies (see voice leading). Illustrative example Lines with parallel harmony can be viewed as a series of chords with the same intervallic structure. Parallel means that each note within the chord rises or falls by the same interval. Examples from works Prominent examples include: * Claude Debussy's '' Beau soir'' (1880), ''Prélude à l'après-midi d'un faune'' (1894), ''Nocturnes'' (1899), '' La Mer'' (1905), ''La cathédrale engloutie'', "Voiles", " Feuilles mortes" * Maurice Ravel's '' Daphnis and Chloë'' Suite No. 2 (1913), "Menuet" from ''Le Tombeau de Couperin'' * Erik Satie's ''Le Fils des étoiles (1892) * Igor Stravinsky's ''The Rite of Spring'' (1913) * Olivier Messiaen's music features abundant planing * Richard Strauss's '' Elektra'' (1909) * Arnold Schoenberg's ''Pierrot lunaire'', "Columbine" (1914) * William ...

Dominant Seventh Chord
In music theory, a dominant seventh chord, or major minor seventh chord, is a seventh chord, usually built on the fifth degree of the major scale, and composed of a root, major third, perfect fifth, and minor seventh. Thus it is a major triad together with a minor seventh, denoted by the letter name of the chord root and a superscript "7". An example is the dominant seventh chord built on G, written as G7, having pitches G–B–D–F: : Dominant seventh chords contain a strong dissonance – a tritone between the chord's third and seventh. Dominant seventh chords are often built on the fifth scale degree (or dominant) of a key. For instance, in the C major scale, G is the fifth note of the scale, and the seventh chord built on G is the dominant seventh chord, G7 (shown above). In this chord, F is a minor seventh above G. In Roman numeral analysis, G7 would be represented as V7 in the key of C major. Similarly, this chord also occurs on the seventh degree of any natural ...

Circle Progression
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The distance between any point of the circle and the centre is called the radius. Usually, the radius is required to be a positive number. A circle with r=0 (a single point) is a degenerate case. This article is about circles in Euclidean geometry, and, in particular, the Euclidean plane, except where otherwise noted. Specifically, a circle is a simple closed curve that divides the plane into two regions: an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is only the boundary and the whole figure is called a '' disc''. A circle may also be defined as a special kin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vi–ii–V–I
__NOTOC__In music, the vi–ii–V–I progression is a chord progression (also called the circle progression for the circle of fifths, along which it travels). A vi–ii–V–I progression in C major (with inverted chords) is shown below. It is "undoubtedly the most common and the strongest of all harmonic progressions" and consists of "adjacent roots in ascending fourth or descending fifth relationship", with movement by ascending perfect fourth being equivalent to movement by descending perfect fifth due to inversion.Bruce Benward and Marilyn Nadine Saker, ''Music In Theory and Practice'', seventh edition, 2 vols. + 2 sound discs (Boston: McGraw-Hill, 2003) 1:178. . For instance, in C major, the chords are Am–Dm–G–C, which have roots that descend by perfect fifth (or ascend by fourth), as shown below.William G Andrews and Molly Sclater (2000). ''Materials of Western Music Part 1'', p.227. . : The circle progression is commonly a succession through all seven diatonic cho ...

Key (music)
In music theory, the key of a piece is the group of pitches, or scale, that forms the basis of a musical composition in classical, Western art, and Western pop music. The group features a '' tonic note'' and its corresponding ''chords'', also called a ''tonic'' or ''tonic chord'', which provides a subjective sense of arrival and rest, and also has a unique relationship to the other pitches of the same group, their corresponding chords, and pitches and chords outside the group. Notes and chords other than the tonic in a piece create varying degrees of tension, resolved when the tonic note or chord returns. The key may be in the major or minor mode, though musicians assume major when this is not specified, e.g., "This piece is in C" implies that the key of the song is C major. Popular songs are usually in a key, and so is classical music during the common practice period, around 1650–1900. Longer pieces in the classical repertoire may have sections in contrasting keys. ...

Thirteenth Chord
In music or music theory, a thirteenth is the note thirteen scale degrees from the root of a chord and also the interval between the root and the thirteenth. The interval can be also described as a compound sixth, spanning an octave plus a sixth. The thirteenth is most commonly major or minor . A thirteenth chord is the stacking of six (major or minor) thirds, the last being above the 11th of an eleventh chord. Thus a thirteenth chord is a tertian (built from thirds) chord containing the interval of a thirteenth, and is an extended chord if it includes the ninth and/or the eleventh. "The jazzy thirteenth is a very versatile chord and is used in many genres." Since 13th chords tend to become unclear or confused with other chords when inverted, they are generally found in root position.Benward & Saker (2009). ''Music in Theory and Practice: Volume II'', p.179. Eighth Edition. . For example, depending on voicing, a major triad with an added major sixth is usually cal ...

Chord Progression
In a musical composition, a chord progression or harmonic progression (informally chord changes, used as a plural) is a succession of chords. Chord progressions are the foundation of harmony in Western musical tradition from the common practice era of Classical music to the 21st century. Chord progressions are the foundation of Western popular music styles (e.g., pop music, rock music), traditional music, as well as genres such as blues and jazz. In these genres, chord progressions are the defining feature on which melody and rhythm are built. In tonal music, chord progressions have the function of either establishing or otherwise contradicting a tonality, the technical name for what is commonly understood as the "key" of a song or piece. Chord progressions, such as the common chord progression I–vi–ii–V, are usually expressed by Roman numerals in Classical music theory. In many styles of popular and traditional music, chord progressions are expressed using the name and " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Major Seventh Chord
In music, a major seventh chord is a seventh chord in which the third is a major third above the root and the seventh is a major seventh above the root. The major seventh chord, sometimes also called a ''Delta chord'', can be written as maj7, M7, , ⑦, etc. The "7" doesn't have to be superscripted, but if it is, then any alterations, added tones, or omissions are usually also superscripted. For example, the major seventh chord built on C, commonly written as Cmaj7, has pitches C–E–G–B: : It can be represented by the integer notation . According to Forte, the major seventh chord is exemplified by IV7, which originates melodically. Forte, Allen (1979). ''Tonal Harmony in Concept & Practice'', p. 150. . : The just major seventh chord is tuned in the ratios 8:10:12:15, as a just major chord is tuned 4:5:6 and a just major seventh is tuned 15:8. The minor-minor sixth chord (minor triad with an added minor sixth) is an inversion of this chord. Examples In 1888, the ...
