LORENZ, ROESSLERE, HENON : MUSIC COMPOSITION FOR CHAMBER ENSEMBLE AND MODULAR SYNTHESIZER

Abstract

The composition Lorenz, Roessler, Henon for chamber ensemble and modular synthesizer are an original contemporary classical music pieces. They were composed based on strange attractor equations which are applied to manage pitch, dynamic and note duration and combined acoustic and electronic composition techniques altogether.

The principle composition technique which is heavily used in the compositions are algorithmic. Furthermore, they are integrating sound design on modular synthesizer. The process of each composition used different approaches on obtaining result from equation. In the first composition, the composer used Micro Ornament and Crime module in Low Rentz mode to obtain the value of Lorenz equation and then took the value of the result to manage pitch, dynamic, duration and dimension of the soumd. The quarter tone and regular equal-temper tuning system were used together by the composer. In the second composition the composer used Max software to aid in finding values from Roessler equation to manage pitch and duration in the composition. In addition, the composer used Euclidean rhythm pattern in the middle part of the composition. In the third composition, the composer used algorithm on software to generate MIDI file and then spread the obtained melody to all instruments in the ensemble according to registration of each instrument. All of 3 compositions used modular synthesizer to play cadenza part, The next procedure is to prepare musical raw material and plan various structures then develop and ensemble all material together to get the composition which has rhythmic, melodic, harmonic and timbre variety. Furthermore, the composition has value in both of structure and appreciation. However, the compositions are challenging according to difficulty in performing and preparation. Thus they needs efficient preparation and rehearsal.
