Flo Menezes' "Parcours de l'Entité" is a lively blend of electro-acoustic sounds - reproduced from a recording - and instrumental live music of flutes and percussion instruments.

"Parcours de l'Entité" is based on harmonic techniques which I have been working on since about 1984: one is the cyclical module, another is proportional projections. The aim of these methods was the development and emergence of harmonic structures derived from complex harmonic figures (entities) with reference to the tempered system (module), as well as to non-tempered sound spaces (projections). In the case of the non- tempered harmonies, a computer program was developed for the Atari computer to calculate the projections.

Although one notices at the beginning of the piece a spectral mixture of the sounds of the flutes and the sounds of the percussion instruments, as this is determined by the sound material of the original tape, gradually a real discord may be heard as it develops between the two sound spheres, finally merging into a melodic structure of the flute in C. This is developed from the middle of the composition to the end of the piece. In this process one can hear a more and more lively layer in the sound material that basically consists of sounds that have been developed through the use of the synthesizer computer program Music V. One could say that the Music V sounds come to replace the percussion instruments after this point, since the computer generated sounds are derived from the "inharmonic" structure of gong tones. The entire composition is nonetheless based on a single symmetrical harmonic figure. It is as though this latent structure were making its own path (its "Parcours") into the constitution of the piece. With the exception of the Music V sounds, all of the sound material was developed from a digital recording of the electroacoustic processing of the sounds of flutes and metal percussion instruments.
