the Aleatorik (of lat. Alea, the cube) designates a bringing of artistic structures out in music , art and literature by means of improvisatorischer or combinatorial coincidence operations.

The term aleatorily is not arbitrarily” or “arbitrary” thereby to equate with “. Aleatorik describes rather a certain, arranged not intentionfulManifestation of an artistic work.

The term Aleatorik is used for the first time 1954 by Werner Meyer Eppler. It takes this term of the Théorie fonctions of the aléatoires of André blank Lapierre and Robert Fortet. Meyer Eppler defines such procedures in the context of the acoustics thereby as aleatory, their process inrough is fixed, in detail however on the coincidence depends (Werner Meyer Eppler, statistic and psychological sound problems, in: those lines 1 up: electronic music. Information about serial music. Vienna 1955, S. 22.)

Aleatory so for instance modulations are in traditional music instruments, which strengthens - construction dependently and by the usedMaterials - easy, impure fluctuations in the Klangbild exhibit, which the listener feels as warm.

Meyer Eppler does not call thus the uncontrolled coincidence aleatory. Only small, noticeable fluctuations are aleatory within a fixed framework.

Aleatory music gets 20 in the music. Century toward end that50's a great importance and stands in connection with the Fluxus - movement. A outstanding exponent of aleatory works is John Cage. Music-historically the use of coincidence operations is in the composition however no earnings/services of the modern trend; already in the Middle Ages Christian monks four threw differentlycurved iron staffs according to the coincidence principle, in order to receive one „beautiful melody “. Also Mozart availed itself in its „musical cube play “the coincidence and left the listener of tome clocks with two cubes at will together cubes.
