Pattern Machine

Patterns are units of information, which are repeated. Patterns can be used visually, as language or words, and as music. They are a principle that has been utilized in almost all style epochs. Many preludes by Johann Sebastian Bach, the accompaniment known as Alberti bass in classical music, or the arabesques in the music of Debussy or Ravel exhibit the rhythmic or melodic use of patterns. The pattern aesthetic became well known through the composers of minimal music, which is constructed exclusively of patterns, especially through Steve Reich. The installation »Pattern Machine«, which was developed in the ZKM | Institute for Music and Acoustics, is an interactive tool for designing musical patterns. »Pattern Machine« formalizes strategies of composition and perception as pattern formation, derivation, and progressive form, and renders them experienceable for visitors.
