YORIAKI MATSUDAIRA : Oto No Hajimari Wo Motomete 12 - ZENEI - ELECTRONICMUSIC EDITION

Transient '64, produced in 1964, composer Yoriaki Matsudaira

In the production process, a cluster of sine waves with a transient tone, referred to as 'transient sound', was created.
The material was created using only transient sounds,
such as the transient oscillation sound produced when a six-channel sine wave oscillator
is switched on before the vacuum tubes are heated,
or the instant a sine wave cluster passes through a damaged loudspeaker.

Assemblages for Tape, produced in 1969, composer Yoriaki Matsudaira

Until now, electronic music has used sound sources with fixed waveforms,
such as sine waves, sawtooth waves, square waves, and white noise.
With these oscillators, it is impossible to create free tones. The photoformer was then conceived.
We thought that if it was possible to create freely drawn waveforms, then it would be possible to create freely drawn tones.
The photoformer was used for the search of a tone imagined from a drawn figure,
but the pulse noise generated by the return time of the cathode ray was so heavily mixed in
that the sound of the drawn waveform was faintly audible, buried in this noise.
The piece was born out of the idea that such sounds were necessary in a work with uncertain sounds.
