Yori-Aki Matsudaira

The first track is 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 second track is 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.
