'''Jazz harmony''' is the [[music theory|theory]] and practice of how [[chord (music)|chords]] are used in [[jazz]] music.


L''''armonia jazz''' è la [[Teoria musicale|teoria]] e la pratica di come gli [[Accordo (musica)|accordi]] sono utilizzati nella [[Jazz|musica jazz]].

== Descrizione ==
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]] [[scale (music)|scales]] as a basis for chordal construction. In jazz, chords are often arranged vertically in [[major third|major]] or [[minor third]]s, although ''[[quartal harmony|stacked fourths]]'' are also quite common.<ref name="Stacking Thirds" /> Also, jazz music tends to favor certain harmonic progressions and includes the addition of ''tensions'', [[interval (music)|intervals]] such as 9ths, 11ths, and 13ths to chords. Additionally, [[jazz scales|scales unique to style]] are used as the basis of many harmonic elements found in jazz. Jazz harmony is notable for the use of [[seventh chord]]s as the basic harmonic unit more often than [[triad (music)|triad]]s, as in [[classical music]].<ref name="Rawlins 2005" /> In the words of [[Robert Rawlins]] and Nor Eddine Bahha, "7th chords provide the building blocks of jazz harmony."<ref name="Rawlins 2005" />

The [[piano]] and [[guitar]] are the two instruments that typically provide harmony for a jazz group. Players of these instruments deal with harmony in a real-time, flowing improvisational context as a matter of course. This is one of the greatest challenges in jazz.

Riga 17 ⟶ 23:

Bebop or "straight-ahead" jazz, in which only certain of all possible extensions and alterations are used, is distinguished from free, avant-garde, or post-bop jazz harmony.<ref name="Rawlins 2005" />

==Chord symbols==

Analytic practice in Jazz recognizes four basic chord types, plus diminished seventh chords. The four basic chord types are ''[[major seventh chord|major]]'', ''[[minor seventh chord|minor]]'', ''[[minor/major seventh chord|minor-major]]'', and ''[[dominant seventh chord|dominant]]''. When written in a jazz ''chart'', these chords may have ''alterations'' specified in parentheses after the chord symbol. An altered note is a note which is a deviation from the canonical chord tone.

Riga 45 ⟶ 51:

It is possible to specify chords with more than four notes. For example, the chord Do-Δ9 contains the notes (Do Mi{{Musica|alterazione|b}} Sol Si D).

== Scala minore melodica ==

==Melodic Minor Scale==

Gran parte dell'armonia jazz si basa sulla [[scala minore melodica]] (usando solo la scala "ascendente" definita nell'armonia classica). I modi di questa scala sono la base per molta improvvisazione jazz e sono variamente chiamati come sotto, usando la chiave di Do-Minore come esempio:
