Nondominant Seventh Chord
In music theory, a nondominant seventh chord is both a diatonic chord and a seventh chord, but it does not possess dominant function, and thus it is ''not'' a dominant seventh chord. Since the V and vii chords are the dominant function chords, the "major minor seventh" V7 and "half-diminished seventh" vii7 are the dominant seventh chords. Since the nondominant function chords are I, i, ii, ii, iii, III, IV, iv, vi, and VI, the nondominant seventh chord qualities include the augmented major seventh chord, major seventh chord, minor major seventh chord, minor seventh chord, and major minor seventh chords that do not possess dominant function, such as, in melodic minor, IV. To analyze seventh chords indicate the quality of the triad; major: I, minor: ii, half-diminished: vii, or augmented: III+; and the quality of the seventh; same: 7, or different: or . With chord letters used to indicate the root and chord quality, and add 7, thus a seventh chord on ii in C major (m ...

Augmented Major Seventh Chord
In music, an augmented major seventh chord or major seventh sharp five chord is a seventh chord composed of a root, major third, augmented fifth, and major seventh (1, 3, 5, 7). It can be viewed as an augmented triad with an additional major seventh. When using popular-music symbols, it is denoted by e.g. +7. For example, the augmented major seventh chord built on A, written as e.g. A+7, has pitches A-C-E-G: : The chord can be represented by the integer notation . The augmented major seventh chord is associated with the augmented scaleCoker, Jerry (1976). ''The Jazz Idiom'', p.66. . (see jazz scale and chord-scale system). This chord also comes from the third mode of both the harmonic minor and the melodic minor scales. For example, the third mode of the A melodic minor scale outlines an augmented major seventh chord, as shown below. : As with dominant seventh chords, nondominant seventh chords including the augmented major seventh usually progress according to the ...

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" does not 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 flat sixth chord (minor triad with an added minor sixth) is an inversion of this chord. Examples In 1888 ...

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. The distance between any point of the circle and the centre is called the radius. The length of a line segment connecting two points on the circle and passing through the centre is called the diameter. A circle bounds a region of the plane called a disc. The circle has been known since before the beginning of recorded history. Natural circles are common, such as the full moon or a slice of round fruit. The circle is the basis for the wheel, which, with related inventions such as gears, makes much of modern machinery possible. In mathematics, the study of the circle has helped inspire the development of geometry, astronomy and calculus. Terminology * Annulus: a ring-shaped object, the region bounded by two concentric circles. * Arc: any connected part of a circle. Specifying two end points of an arc and a centre allows for two arcs that together make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Circle Of Fifths
In music theory, the circle of fifths (sometimes also cycle of fifths) is a way of organizing pitches as a sequence of perfect fifths. Starting on a C, and using the standard system of tuning for Western music (12-tone equal temperament), the sequence is: C, G, D, A, E, B, F/G, C/D, G/A, D/E, A/B, F, and C. This order places the most closely related key signatures adjacent to one another. Twelve-tone equal temperament tuning divides each octave into twelve equivalent semitones, and the circle of fifths leads to a C seven octaves above the starting point. If the fifths are tuned with an exact frequency ratio of 3:2 (the system of tuning known as just intonation), this is not the case (the circle does not "close"). Definition The circle of fifths organizes pitches in a sequence of perfect fifths, generally shown as a circle with the pitches (and their corresponding keys) in clockwise order. It can be viewed in a counterclockwise direction as a circle of fourths. Harmonic progres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Resolution (music)
Resolution in Western tonal music theory is the move of a Musical note, note or chord (music), chord from Consonance and dissonance, dissonance (an unstable sound) to a Consonance and dissonance, consonance (a more final or stable sounding one). Dissonance, resolution, and suspense can be used to create musical interest. Where a melody or chord progression, chordal pattern is expected to resolve to a certain note or chord, a different but similarly suitable note can be resolved to instead, creating an interesting and unexpected sound. For example, the deceptive cadence. Basis Resolution has a strong basis in Tonality, tonal music, since atonal music generally contains a more constant level of Consonance and dissonance, dissonance and lacks a tonal center to which to resolve. The concept of "resolution", and the degree to which resolution is "expected", is contextual as to culture and historical period. In a classical piece of the Baroque music, Baroque period, for example, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Major And Minor
In Western music, the adjectives major and minor may describe an interval, chord, scale, or key. A composition, movement, section, or phrase may also be referred to by its key, including whether that key is major or minor. The words derive from Latin words meaning "large" and "small," and were originally applied to the intervals between notes, which may be larger or smaller depending on how many semitones (half-steps) they contain. Chords and scales are described as major or minor when they contain the corresponding intervals, usually major or minor thirds. Intervals A major interval is one semitone larger than a minor interval. The words ''perfect'', ''diminished'' and ''augmented'' are also used to describe the quality of an interval. Only the intervals of a second, third, sixth, and seventh (and the compound intervals based on them) may be major or minor (or, rarely, diminished or augmented). Unisons, fourths, fifths, and octaves and their compound interval must be p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Root (chord)
In the music theory of harmony, the root is a specific Note (music), note that names and typifies a given chord (music), chord. Chords are often spoken about in terms of their root, their Chord quality, quality, and their Chord extensions, extensions. When a chord is named without reference to quality, it is assumed to be major chord, major—for example, a "C chord" refers to a C major triad, containing the notes C, E, and G. In a given harmonic context, the root of a chord need not be in bass note, the bass position, as chords may be Inversion (music), inverted while retaining the same name, and therefore the same root. In tertian harmonic theory, wherein chords can be considered stacks of third intervals (e.g. in common practice period, common practice tonality), the root of a chord is the Musical note, note on which the subsequent thirds are stacked. For instance, the root of a triad (music), triad such as E Minor is E, independently of the vertical order in which the three n ...

Chord Letters
Musicians use various kinds of chord names and symbols in different contexts to represent musical chords. In most genres of popular music, including jazz, pop, and rock, a chord name and its corresponding symbol typically indicate one or more of the following: * the root note (e.g. C) * the chord quality (e.g. minor or lowercase m, or the symbols or + for diminished and augmented chords, respectively; chord quality is usually omitted for major chords) * whether the chord is a triad, seventh chord, or an extended chord (e.g. 7) * any altered notes (e.g. sharp five, or 5) * any added tones (e.g. add2) * the bass note if it is not the root (e.g. a slash chord) For instance, the name C augmented seventh, and the corresponding symbol C, or C, are both composed of parts 1 (letter 'C'), 2 ('aug' or '+'), and 3 (digit '7'). These indicate a chord formed by the notes C–E–G–B. The three parts of the symbol (C, aug, and 7) refer to the root C, the augmented (fifth) interval ...

Seventh (chord)
In music, the seventh factor (chord), factor of a chord (music), chord is the note (music), note or pitch (music), pitch seven scale degrees above the root (chord), root or tonality, tonal center.Riemann, Hugo. Dictionary of Music'. Trans. J.A. Shedlock. Augener, 1900. 730. When the seventh is the bass note, or lowest note, of the expressed chord, the chord is in third inversion . Conventionally, the seventh is fourth in importance to the root, fifth (chord), fifth, and third (chord), third, with third inversion being the third strongest Inversion (interval), inversion and the seventh variably minor or major. In jazz In jazz chords and theory, and classical music theory, the seventh is what defines a chord as a "seventh chord". Moreover, most triad (music), triads that appear in lead sheets or fake books can have sevenths added to them, using the performer's discretion and "ear". For example, if a tune is in the key of C, if there is a G chord, the chord-playing performer will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Augmented Chord
An augmented triad is a chord (music), chord, made up of two major thirds (an augmented fifth). The term ''augmented triad'' arises from an augmented triad being considered a major chord whose top note (fifth) is raised. When using Chord names and symbols (popular music), popular-music symbols, it is indicated by the symbol "+" or "aug". For example, the augmented triad built on A, written as A+, has pitches A-C-E: The chord can be represented by the Pitch class#Integer notation, integer notation . Analysis Whereas a Major chord, major triad, such as C–E–G, contains a major third (C–E) and a minor third (E–G), with the interval of the fifth (C–G) being Interval quality, perfect, the augmented triad has an augmented fifth, becoming C–E–G. In other words, the top note is raised a semitone. H.R. Palmer notes: The augmented chord on I may contain the Augmented major seventh chord, major seventh (I () or I ()), while the augmented chord on V may contain the Augment ...

Minor Chord
In music theory, a minor chord is a chord that has a root, a minor third, and a perfect fifth. When a chord comprises only these three notes, it is called a minor triad. For example, the minor triad built on A, called an A minor triad, has pitches A–C–E: In harmonic analysis and on lead sheets, a C minor chord can be notated as Cm, C−, Cmin, or simply the lowercase "c". A minor triad is represented by the integer notation . A minor triad can also be described by its intervals: the interval between the bottom and middle notes is a minor third, and the interval between the middle and top notes is a major third. By contrast, a major triad has a major third on the bottom and minor third on top. They both contain fifths, because a minor third (three semitones) plus a major third (four semitones) equals a perfect fifth (seven semitones). Chords that are constructed of consecutive (or "stacked") thirds are called '' tertian.'' In Western classical music from 1600 to ...
