Usul: Aksak Routine by Omercho published on 2014-05-20T11:42:23Z "Usul: Aksak Routine" is an algorithmic performance of electroacoustic music based on the rythmic system Usul of Turkish music. The term usul, which includes both the concepts of meter (measure) and rhythm, defines the rhythmic elements of all the structured musical pieces of the system. Every usul is a recurrent rhythmic circle – something similar of meter in western music – a model with a name and a pattern. The usuls are performed in beats, known in Turkish as "darp". Also the usuls are named according to the length and form of their beats and they are divided into two main groups, Minor usuls and Major usuls. The minors are those of 2 to 15 beats. The majors are those containing from 16 to 124 beats. The goal of this project is the use of minor usuls to create diffrent major usuls in real time. The current multichannel (4ch to 8ch) piece consists of 6 sound sources. Each one of them returns a different minor usul, with samples created using the physical modeling software Genesis and SuperCollider. Every darp (beat) produced with graining effects in SuperCollider. The rhythmic patterns and the sound spatialization are generated with original programs and routines, written also in SuperCollider. For controller in performance I am using a multitouch OSC controller. Genre Electroacoustic
