Berlin-Tokyo based performer and artist, founder of label Basic Function. His practice si focused on self-made instruments, improvisations and audio-visual installation work.
- Self-made instruments
Kachi – Kachi
The instrument uses electromagnetic relay. A relay is an electrically operated switch used to switch higher voltage from lower voltages.
It consists of a coil wrapped around a core. When the current goes through the coil a it produces a magnetic field pulling at the metal plates. The clicking sound is produced by the metal plates hitting the core.
The instrument can therefore be considered an acoustic oscillator. Each unit has its’ own frequency, which, when played together, creates parallel rhythms – when combined they produce interesting textures (moire effect).
- Installation
Oshiro’s installation work is based around beating frequencies. A beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies:
fbeat=`|f1-f2|
Strings (2014)
- single strobe frequency oscillating between 23.5Hz and 24Hz (chose so that the wave would be in its’ positive phase, it reaches 25Hz at times, which causes the string to stop vibrating)
- single 50Hz sinewave playing back through the subwoofer
- 14 strings (of different lengths) stretching out across the room, tuned into different tensions.
Several strings are tied to a subwoofer that emits a low frequency sine wave; the strings are stretched to certain points in the exhibition space. When the stretched strings are tuned to certain tensions, the vibration of the subwoofer passes on to the strings, causing them to oscillate and depict waveforms. The exhibition space is lit up using a strobe light that flickers at a varying frequency that interferes with the string vibration, allowing us to see the string movements at a much slower frequency than what is actually happening. Although the result of the interference that occurs between the two frequencies is repetitive, the strings are tuned to move rather in an organic way.
Mono-poly (2017)
- similar concept as Strings;
- the string splits in multiple components;
- this piece explored how to control the movement of a single string and work with multiple frequencies at the same time.
