Tension tone

from Wikipedia, the free encyclopedia

Under a Spannungston (also: voltage Score ) is understood in the music a sound , the function of the pitch generates a musical tension or expectation; A tone of tension is assigned a need for resolution that arises from the listener's expectation. In the key of C major , for example, an F played in addition to the C major chord (C + G) is such a tension note, because the resulting sound does not sound stable, but triggers an expectation. He must , for example, F-Dur (from the tonic to the dominant in the classical harmony I-IV-VI compound ) continue or be completed with a C-major. Or a dissonance created by a tone of tension dissolves into a consonance .

Musical tension can be achieved not only through tension tones, but also through repetition or the gradual or continuous increase in pitch .

In the jazz harmonic tension tones with Engl. Tension notes , or tension tones for short , that can be added to a chord.

Tensions

In jazz , the optional tones 9, 11 and 13 are mainly used in an altered form ( ♭ 9, ♯ 9, ♯ 4 / ♭ 5, ♭ 13) as tension tones and used as additional tones in (extended) dominant seventh chords . Compared to option tones 9, 11 and 13, which are included in the tonality scale , altered option tones create more tension.

The guitarist and author Mathias Löffler differentiates tensions in option tones (9, 11, ♯ 11, 13) and their alterations ( ♭ 9, ♯ 9 and ♭ 13), whereby he describes ♯ 11 as an option tone. He explained by the fact that the sound ♯ 11 at best aspire within the dominant seventh to fifth, but not the dominant even urge a resolution.

The (extended) dominant seventh chords are usually notated in chordsheets with given tensions, for example G 9 is the dominant seventh chord on G, the fifth degree in C major, which has been extended with 9 as an option tone. In the chord notation, the symbol V is sometimes used for the fifth level. Extended dominant seventh chords often used in jazz are, in this notation, for example: V9 (with 9 as an option tone), Gsus9 (with 4 and 9), V7b9 (with ♭ 9 as an alternate optional tone), V13b9 (with ♭ 9 and 13), Vaug7 (with # 5) and Vaug7b9 (with # 5 and ♭ 9).
