Common-chord (music)
A common chord, in the theory of harmony, is a chord that is diatonic to more than one key or, in other words, is ''common'' to (shared by) two keys. A "common chord" may also be defined simply as a triadic chord (e.g., C–E–G), as one of the most commonly used chords in a key (I–IV–V–vi–ii), more narrowly as a triad in which the fifth is perfect (i.e., a major or minor triad), in which sense it is alternatively referred to as a "perfect chord" or, more narrowly still (in American practice), as a major triad only.Don Michael Randel, "Common Chord", ''Harvard Dictionary of Music'', fourth edition, Harvard University Press Reference Library 16 (Cambridge: Harvard University Press 2003): 193. . "Common chord: Major triad." Common chords are frequently used in modulations, in a type of modulation known as common chord modulation or diatonic pivot chord modulation. It moves from the original key to the destination key (usually a closely related key) by way of a chord both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Root (chord)
In music theory, the concept of root is the idea that a chord (music), chord can be represented and named by one of its Musical note, notes. It is linked to Harmony (music), harmonic thinking—the idea that vertical aggregates of notes can form a single unit, a chord. It is in this sense that one speaks of a "C chord" or a "chord on C"—a chord built from C and of which the note (or pitch) C is the root. When a chord is referred to in Classical music or popular music without a reference to what type of chord it is (either major or minor, in most cases), it is assumed a major triad, which for C contains the notes C, E and G. The root need not be the bass note, the lowest note of the chord: the concept of root is linked to that of the Inverted chord, inversion of chords, which is derived from the notion of Invertible Counterpoint, invertible counterpoint. In this concept, chords can be inverted while still retaining their root. In tertian harmonic theory, wherein chords can be con ...

Common Tone (scale)
In music, a common tone is a pitch class that is a member of, or common to (shared by) two or more scales or sets. Common tone theorem A common tone is a pitch class that is a member of, or common to, a musical scale and a transposition of that scale, as in modulation. Six of seven possible common tones are shared by closely related keys, though keys may also be thought of as more or less closely related according to their number of common tones. "Obviously, tonal distance is in some sense a function of the extent of intersection between diatonic PC collections of tonal systems". In diatonic set theory the common tone theorem explains that scales possessing the deep scale property share a different number of common tones, not counting enharmonic equivalents (for example, C and C have no common tones with C major), for every different transposition of the scale. However many times an interval class occurs in a diatonic scale is the number of tones common both to the origin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Tone (chord)
In music, a common tone is a pitch class that is a member of, or common to (shared by) two or more chords or sets. Typically, it refers to a note shared between two chords in a chord progression. According to H.E. Woodruff: The example below shows the seven diatonic triads of C major. The common tones between the tonic triad and the other six triads are highlighted in blue. As Woodruff describes, the tonic triad shares ''no'' common tones with either II and VII (consecutive to I), ''one'' common tone with IV and V (four and five degrees from I) each, and ''two'' common tones with III and VI (three and six degrees from I) each. : In voice leading Common tones are a consideration in voice leading and voicing. Abbé Vogler (1749–1814), Weber (1779–1839), Hauptmann (1792–1868), A. B. Marx (1795–1866), and earlier theorists emphasized "common-tone retention and smooth voice leading in... heirtreatment of harmonic succession hord progressions . It may be considered ...

Enharmonic Scale
In music theory, an enharmonic scale is "an maginarygradual progression by quarter tones" or any " usicalscale proceeding by quarter tones". The enharmonic scale uses dieses (divisions) nonexistent on most keyboards,John Wall Callcott (1833). ''A Musical Grammar in Four Parts'', p.109. James Loring. since modern standard keyboards have only half-tone dieses. More broadly, an enharmonic scale is a scale in which (using standard notation) there is no exact equivalence between a sharpened note and the flattened note it is enharmonically related to, such as in the quarter tone scale. As an example, F and G are equivalent in a chromatic scale (the same sound is spelled differently), but they are different sounds in an enharmonic scale. See: musical tuning. Musical keyboards which distinguish between enharmonic notes are called by some modern scholars enharmonic keyboards. (The enharmonic genus, a tetrachord with roots in early Greek music, is only loosely related to enharmonic sca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subdominant
In music, the subdominant is the fourth tonal degree () of the diatonic scale. It is so called because it is the same distance ''below'' the tonic as the dominant is ''above'' the tonicin other words, the tonic is the dominant of the subdominant. It also happens to be the note one step below the dominant. In the movable do solfège system, the subdominant note is sung as ''fa''. The triad built on the subdominant note is called the subdominant chord. In Roman numeral analysis, the subdominant chord is typically symbolized by the Roman numeral "IV" in a major key, indicating that the chord is a major triad. In a minor key, it is symbolized by "iv", indicating that the chord is a minor triad. These chords may also appear as seventh chords: in major, as IVM7, or in minor as iv7 or sometimes IV7: A cadential subdominant chord followed by a tonic chord produces the so-called plagal cadence. As with other chords which often precede the dominant, subdominant chords typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominant (music)
In music, the dominant is the fifth scale degree () of the diatonic scale. It is called the ''dominant'' because it is second in importance to the first scale degree, the tonic. In the movable do solfège system, the dominant note is sung as "So(l)". The triad built on the dominant note is called the dominant chord. This chord is said to have dominant function, which means that it creates an instability that requires the tonic for resolution. Dominant triads, seventh chords, and ninth chords typically have dominant function. Leading-tone triads and leading-tone seventh chords may also have dominant function. Dominant chords In music theory, the dominant triad is a major chord, symbolized by the Roman numeral "V" in the major scale. In the natural minor scale, the triad is a minor chord, denoted by "v". However, in a minor key, the seventh scale degree is often raised by a half step ( to ), creating a major chord. These chords may also appear as seventh chords: ty ...

Relative Major
In music, relative keys are the major and minor scales that have the same key signatures (enharmonically equivalent), meaning that they share all the same notes but are arranged in a different order of whole steps and half steps. A pair of major and minor scales sharing the same key signature are said to be in a relative relationship. The relative minor of a particular major key, or the relative major of a minor key, is the key which has the same key signature but a different tonic. (This is as opposed to ''parallel'' minor or major, which shares the same tonic.) For example, F major and D minor both have one flat in their key signature at B♭; therefore, D minor is the relative minor of F major, and conversely F major is the relative major of D minor. The tonic of the relative minor is the sixth scale degree of the major scale, while the tonic of the relative major is the third degree of the minor scale. The minor key starts three semitones below its relative major; for example ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diatonic Functionality
In music, function (also referred to as harmonic function) is a term used to denote the relationship of a chord"Function", unsigned article, ''Grove Music Online'', . or a scale degree to a tonal centre. Two main theories of tonal functions exist today: * The German theory created by Hugo Riemann in his ''Vereinfachte Harmonielehre'' of 1893, which soon became an international success (English and Russian translations in 1896, French translation in 1899), and which is the theory of functions properly speaking."It was Riemann who coined the term 'function' in ''Vereinfachte Harmonielehre'' (1893) to describe relations between the dominant and subdominant harmonies and the referential tonic: he borrowed the word from mathematics, where it was used to designate the correlation of two variables, an 'argument' and a 'value'". Brian Hyer, "Tonality", ''Grove Music Online'', . Riemann described three abstract tonal "functions", tonic, dominant and subdominant, denoted by the letters T, ...

Predominant Chord
In music theory, a predominant chord (also pre-dominant) is any chord which normally resolves to a dominant chord.Benward & Saker (2009). ''Music in Theory and Practice: Volume II'', Glossary, p.359. Eighth Edition. . "Any chord in functional harmony that normally resolves to the dominant chord." Examples of predominant chords are the subdominant (IV, iv), supertonic (ii, ii°), Neapolitan sixth and German sixth. Other examples are the secondary dominant (V/V) and secondary leading tone chord. Predominant chords may lead to secondary dominants. Predominant chords both expand away from the tonic ''and'' lead to the dominant, affirming the dominant's pull to the tonic.Cleland, Kent D. and Dobrea-Grindahl, Mary (2013). ''Developing Musicianship Through Aural Skills: A Holistic Approach to Sight Singing and Ear Training'', p.255. Routledge. . Thus they lack the stability of the tonic and the drive towards resolution of the dominant. The predominant harmonic function is part of the ...

Major And Minor
In Western music, the adjectives major and minor may describe a chord, scale, or key. As such, composition, movement, section, or phrase may be referred to by its key, including whether that key is major or minor. Intervals Some intervals may be referred to as ''major'' and ''minor''. 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 perfect (or, rarely, diminished or augmented). In Western music, a minor chord "sounds darker than a major chord". Kamien, Roger (2008). ''Music: An Appreciation'', 6th Brief Edition, p. 46. . Scales and chords The other uses of ''major'' and ''minor'' generally refer to scales and ...

Chord (music)
A chord, in music, is any harmonic set of pitches/frequencies consisting of multiple notes (also called "pitches") that are heard as if sounding simultaneously. For many practical and theoretical purposes, arpeggios and broken chords (in which the notes of the chord are sounded one after the other, rather than simultaneously), or sequences of chord tones, may also be considered as chords in the right musical context. In tonal Western classical music (music with a tonic key or "home key"), the most frequently encountered chords are triads, so called because they consist of three distinct notes: the root note, and intervals of a third and a fifth above the root note. Chords with more than three notes include added tone chords, extended chords and tone clusters, which are used in contemporary classical music, jazz and almost any other genre. A series of chords is called a chord progression. One example of a widely used chord progression in Western traditional music and blu ...
