Jazz improvisation is the spontaneous invention of melodic solo lines or accompaniment parts in a performance of jazz music. It is one of the defining elements of jazz. Improvisation is composing on the spot, when a singer or instrumentalist invents melodies and lines over a chord progression played by rhythm section instruments (piano, guitar ...
For instance, in C major, a jazz musician may alter the V chord, G 7 (G–B–D–F), with a flattened fifth, producing the chord G 7 ♭ 5 (G–B–D ♭ –F). An improviser might then choose a scale containing these four notes, such as the G whole tone scale, the G octatonic scale, or a mode of either D or A ♭ melodic minor ascending.
Thus, this upper structure can be called upper structure flat three, or US ♭ III for short. Other possible upper structures are: USII – e.g. D major over C 7, resulting in C 13 ♯ 11; US ♭ V – e.g. G ♭ major over C 7, resulting in C 7 ♭ 9 ♯ 11; US ♭ VI – e.g. A ♭ major over C 7, resulting in C 7 ♯ 9 ♭ 13; USVI – e.g ...
5-34. The jazz minor scale or ascending melodic minor scale is a derivative of the melodic minor scale, except only the ascending form of the scale is used. As the name implies, it is primarily used in jazz [citation needed], although it may be found in other types of music as well. It may be derived from the major scale with a minor third, [ 1 ...
It was added as a counter-melody to the song's "muddy shoes" guitar part, [6] and it is this hook that the Edge plays during live performances of the song. Bono sang in the upper register of his range to add to the feeling of spiritual yearning; in the verses he hits a B-flat note, and an A-flat in the chorus. [7]
Altered scale. In jazz, the altered scale, altered dominant scale, or Super Locrian scale ( Locrian ♭4 scale) is a seven-note scale that is a dominant scale where all non-essential tones have been altered. This means that it comprises the three irreducibly essential tones that define a dominant seventh chord, which are root, major third, and ...
Jazz harmony is the theory and practice of how chords are used in jazz music. Jazz bears certain similarities to other practices in the tradition of Western harmony, such as many chord progressions, and the incorporation of the major and minor scales as a basis for chordal construction. In jazz, chords are often arranged vertically in major or ...
Outside (jazz) In jazz improvisation, outside playing describes approaches 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, [1] and polytonality.
