Utilizing sine waves – sound without any distortion and representing a single frequency – the members of the SineWave Orchestra carry out performances in which the public participate.

Anyone can take part to it if he/she can produce a sine wave. The performance is carried out in a place with all the participants concurrently. Each participant produces only one sine wave. The sine waves, which are the simplest elements of sound, arise from each speaker and are interfered in the real space. Then, the sea of sine waves will appear.

So far, people were mainly using laptops. During the Yokohama Triennale, TSWO will hold participatory performances six times during the Triennale. Each participant is asked to hold an i-pod that is emitting the sound based on sine wave. Depending on where each performer is standing in the space, the sound will be in various degrees of synch. After the performance, i-pods are installed inside the warehouse.
