Example 1: Below, a common voicing used by jazz pianists is given for the chord C 7 ♯ 9 (C major chord with a minor 7th, and extended with an augmented 9th). In the lower stave the notes E ♮ and B ♭ are given. These form a tritone which defines the dominant sound, and are the major 3rd and minor 7th of the C 7 ♯ 9 chord.
An illustration shows this C7 voicing (C, E, G, B ♭), which would be extremely difficult to play in standard tuning, [30] besides the openly voiced C7-chord that is conventional in standard tuning: [30] This open-position C7 chord is termed a second-inversion C7 drop 2 chord (C, G, B ♭, E), because the second-highest note (C) in the second ...
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 ...
The tritone substitution is a common chord substitution found in both jazz and classical music. Where jazz is concerned, it was the precursor to more complex substitution patterns like Coltrane changes. Tritone substitutions are sometimes used in improvisation —often to create tension during a solo.
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 ...
The two octatonic scales on C. An octatonic scale is any eight- note musical scale. However, the term most often refers to the ancohemitonic symmetric scale composed of alternating whole and half steps, as shown at right. In classical theory (in contrast to jazz theory ), this symmetrical scale is commonly called the octatonic scale (or the ...
Jazz guitar may refer to either a type of electric guitar or a guitar playing style in jazz, using electric amplification to increase the volume of acoustic guitars. In the early 1930s, jazz musicians sought to amplify their sound to be heard over loud big bands. When guitarists in big bands switched from acoustic to semi-acoustic guitar and ...
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.
