Acoustic scale

The acoustic scale ( also Overtone Scale, Lydian Dominant, Lydian ♭ 7 or Mixo ♯ 11) is a heptatonic diatonic scale. She is the first mode of Heptatonia Secunda. The term was coined by Acoustic scale Ernő Lendvai.

Derivation

To derive the harmonic series can be used, in which the partials 8-14 (modified in the equal temperament ) correspond to the acoustic scale. You can also alternatively as the minor scale C7 ♯ 11 chord (ie consisting of C, E, G, B, D, F #, A) interpret, which is therefore also referred to as an acoustic Tredezimakkord.

Another possible interpretation is the change of church modes. This allows the acoustic scale as the Lydian mode consider its seventh tone was tiefalteriert: This results in the ( English ) name " Lydian ♭ 7". The alternative name " Mixo ♯ 11 " refers to a Mixolydian scale, which contains a tritone above the root ( the fourth tone was ergo hochalteriert, recorded by jazz habit as 11 tone or eleventh ).

Use

First used is the scale in the music of the 19th century. Already Franz Liszt used frequently ( eg in the Années de pèlerinage or third Mephisto Waltz ), and later Maurice Ravel and Claude Debussy involve them in some of their works one ( for example, in La Mer ). Part excessive use of the acoustic scale, Alexander Scriabin, which he used, among other things for its mystic chord. More examples can be in Béla Bartók, Igor Stravinsky, Olivier Messiaen, or find.
