Added tone chord
As Optionston or a secondary audio option is referred to the considered chord in jazz harmony. These tones can - for example, when improvising or playing along with a soloist by a harmony instrument (piano or guitar) - optional, will therefore either played or omitted because they are not important to the character of the chord. Since one in jazz harmony, in contrast to classic harmony of four, rather than three chord tones emanating, the seventh of a chord counts not always as Optionston. The options of a jazz chord are therefore the ninth, the eleventh and the thirteenth ( one goes in the naming of the intervals from a Terzschichtung of the chord: root ( 1), third ( 3), fifth ( 5), seventh ( 7), None, (9 ), eleventh (11 ), thirteenth (13)).
For example, the chord tones are in a dominant seventh chord on the root G h ( third), d ( fifth) and f ( seventh), that the Rings are located above a ( None), c ( eleventh ) and e ( thirteenth ); the same applies to minor ( Sept ) chords. However, it should be ensured that the eleventh in a major chord a very strong tension with the third of the chord results and this option is therefore ( except as a passing tone ) is very rarely actually played.
Each Optionston, depending on the harmonic context, altered, that is changed chromatic.
