Seventh Chords
A seventh chord is a chord consisting of a triad plus a note forming an interval of a seventh above the chord's root. When not otherwise specified, a "seventh chord" usually means a dominant seventh chord: a major triad together with a minor seventh. However, a variety of sevenths may be added to a variety of triads, resulting in many different types of seventh chords. In its earliest usage, the seventh was introduced solely as an embellishing or nonchord tone. The seventh destabilized the triad, and allowed the composer to emphasize movement in a given direction. As time passed and the collective ear of the western world became more accustomed to dissonance, the seventh was allowed to become a part of the chord itself, and in some modern music, jazz in particular, . Additionally, the general acceptance of equal temperament during the 19th century reduced the dissonance of some earlier forms of sevenths.

Dominant Seventh Chord
Domination or dominant may refer to: Society * World domination, structure where one dominant power governs the planet * Colonialism in which one group (usually a nation) invades another region for material gain or to eliminate competition * Chauvinism in which a person or group consider themselves to be superior, and thus entitled to use force to dominate others * Sexual dominance involving individuals in a subset of BDSM behaviour * Hierarchy Music * Dominant (music), a diatonic scale step and diatonic function in tonal music theory Albums * ''Domination'' (Cannonball Adderley album) or the title track, 1965 * ''Domination'' (Morbid Angel album), 1995 * ''Domination'', by Domino, 2004 * ''Domination'', by Morifade, 2004 Songs * "Domination" (song), by Pantera, 1990 * "Domination", by Band-Maid from ''World Domination'', 2018 * "Domination", by Symphony X from ''Paradise Lost'', 2007 * "Domination", by Way Out West from '' Way Out West'', 1996 * "Domination", by Within t ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Major Second
In Western music theory, a major second (sometimes also called whole tone or a whole step) is a second spanning two semitones (). A second is a musical interval encompassing two adjacent staff positions (see Interval number for more details). For example, the interval from C to D is a major second, as the note D lies two semitones above C, and the two notes are notated on adjacent staff positions. Diminished, minor and augmented seconds are notated on adjacent staff positions as well, but consist of a different number of semitones (zero, one, and three). The major second is the interval that occurs between the first and second degrees of a major scale, the tonic and the supertonic. On a musical keyboard, a major second is the interval between two keys separated by one key, counting white and black keys alike. On a guitar string, it is the interval separated by two frets. In moveable-do solfège, it is the interval between ''do'' and ''re''. It is considered a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diminished Third
In classical music from Western culture, a diminished third () is the interval (music), musical interval produced by Diminution, narrowing a minor third by a chromatic semitone.Benward & Saker (2003). ''Music: In Theory and Practice, Vol. I'', p.54. . For instance, the interval from A to C is a minor third, three semitones wide, and both the intervals from A to C, and from A to C are diminished thirds, two semitones wide. Being diminished, it is considered a consonance and dissonance, dissonant interval. In 12-tone equal temperament a diminished third is enharmonic with the major second, both having a value of 200 cent (music), cents. However, in meantone temperament, meantone tunings with fifths flatter than 700 cents, the diminished third is wider than the major second. In 19 equal temperament it is in fact enharmonically equivalent to an augmented second, both having a value of 252.6 cents. In 31 equal temperament it has a more typical value of 232.3 cents. In a twelve-note ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augmented Seventh Chord
The augmented seventh chord, or seventh augmented fifth chord, or seventh sharp five chord is a seventh chord composed of a root, major third, augmented fifth, and minor seventh (1, 3, 5, 7).Garner, Robert (2007). ''Mel Bay Presents Essential Music Theory for Electric Bass'', p. 69. . It can be viewed as an augmented triad with a minor seventh. When using popular-music symbols, it is denoted by +7, aug7, or 75. For example, the augmented seventh chord built on A, written as A+7, has pitches A-C-E-G: : The chord can be represented by the integer notation . Use The root is the only optional note in an augmented seventh chord, the fifth being required because it is raised. This alteration is useful in the major mode because the raised 5th creates a leading tone to the 3rd of the tonic triad. See also dominant. In rock parlance, the term ''augmented seventh chord'' is sometimes confusingly and erroneously used to refer to the so-called " Hendrix chord", a 79 chord which ...

Augmented Fifth
In Western classical music, an augmented fifth () is an interval produced by widening a perfect fifth by a chromatic semitone.Benward & Saker (2003). ''Music: In Theory and Practice, Vol. I'', p.54. . For instance, the interval from C to G is a perfect fifth, seven semitones wide, and both the intervals from C to G, and from C to G are augmented fifths, spanning eight semitones. Being augmented, it is considered a dissonant interval. Its inversion is the diminished fourth, and its enharmonic equivalent is the minor sixth. The augmented fifth only began to make an appearance at the beginning of the common practice period of music as a consequence of composers seeking to strengthen the normally weak seventh degree when composing music in minor modes. This was achieved by chromatically raising the seventh degree (or subtonic) to match that of the unstable seventh degree (or leading tone) of the major mode (an increasingly widespread practice that led to the creation ...

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 ...

Minor Major Seventh Chord
A minor major seventh chord, or minor/major seventh chord (also known as the Hitchcock Chord) is a seventh chord composed of a root, minor third, perfect fifth, and major seventh (1, 3, 5, and 7). It can be viewed as a minor triad with an additional major seventh. When using popular-music symbols, it is denoted by e.g. m(M7). For example, the minor major seventh chord built on A, written as e.g. Am(M7), has pitches A-C-E-G: : The chord can be represented by the integer notation . Use The chord occurs on the tonic when harmonizing the harmonic minor scale in seventh chords. That is, the first, third, fifth, and seventh scale degrees of the harmonic minor scale form a minor major seventh chord, as shown below. : The harmonic minor scale has a raised seventh, creating a minor second (half step) between the seventh and the octave. This half step creates a pull (leading tone) to the tonic that is useful in harmonic context and is not present in the natural minor scale ...

Diminished Seventh
In classical music from Western culture, a diminished seventh () is an interval (music), interval produced by Diminution, narrowing a minor seventh by a chromatic semitone,Benward & Saker (2003). ''Music: In Theory and Practice, Vol. I'', p.54. . Specific example of an d7 not given but general example of minor intervals described. and its Inversion (interval), inversion is the augmented second. For instance, the interval from A to G is a minor seventh, ten semitones wide, and both the intervals from A to G, and from A to G are diminished sevenths, spanning nine semitones. Being diminished, it is considered a consonance and dissonance, dissonant interval. The diminished seventh is used quite readily in the minor key, where it is present in the harmonic minor scale between the seventh scale step and the sixth scale step in the octave above. In 12-tone equal temperament, a diminished seventh is equal to nine semitones, a ratio of 29/12:1 (approximately 1.6818), or 900 cents, and i ...

Diminished Seventh Chord
The diminished seventh chord is a four-note chord (a seventh chord) composed of a Root (chord), root note, together with a minor third, a diminished fifth, and a diminished seventh above the root: (1, 3, 5, 7). For example, the diminished seventh chord built on B, commonly Chord names and symbols (popular music), written as B7, has pitches B-D-F-A: : The chord consists of a diminished triad plus the diminished seventh above the root. These four notes form a stack of three Interval (music), intervals which are all minor thirds. Since stacking yet another minor third returns to the root note, the four Inversion (music), inversions of a diminished seventh chord are symmetrical. The Pitch class#Integer notation, integer notation is . Since the diminished seventh interval is enharmonically equivalent to a major sixth, the chord is enharmonically equivalent to (1, 3, 5, 6). The diminished seventh chord occurs as a leading-tone seventh chord in the harm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half-diminished Seventh Chord
In music theory, the half-diminished seventh chord (also known as a half-diminished chord or a minor seventh flat five chord) is a seventh chord composed of a Root (chord), root note, together with a minor third, a tritone, diminished fifth, and a minor seventh (1, 3, 5, 7). For example, the half-diminished seventh chord built on B, commonly Chord names and symbols (popular music), written as Bm7(♭5), or B7, has pitches B-D-F-A: : It can be represented by the Pitch class#Integer notation, integer notation . The half-diminished seventh chord exists in root position and in three inversions. The first inversion is enharmonic to a minor sixth chord: In diatonic harmony, the half-diminished seventh chord occurs naturally on the seventh scale degree of any major scale (for example, B7 in C major) and is thus a leading-tone seventh chord in the major mode.Benward & Saker (2003).
