Beatriz Ferreyra has been at the forefront of electroacoustic music since 1963, when she joined the GRM as one of Pierre Schaeffer’s research assistants. At Schaeffer’s studios, she developed her own research project Objets Construits (constructed objects). These are layers of short sounds, chords of different noises. Each layer is isolated on a separate piece of tape to analyse the relationships between components, and the effect of minimal alterations in pitch, dynamics, morphology of sounds or timing on the overall perception of the chord.
