I created this piece remembering an article Ryuichi Sakamoto contributed to a stereogram book (C.G.ステレオグラム: 驚異の3D) when I was in elementary school, discussing stereoscopic sound in the context of polyphony. I placed it at the end as an homage to Hideki Matsutake's "Closing world for future" from the YMO remix album "YMO-REMIXES TECHNOPOLIS 2000-00".
Come to think of it, I once created and performed an MML (Master Music Line) piece for a five-person ensemble in Mabinogi.
I used a TB-303 for the cello's bass, placed gamelan instruments on both the left and right edges of the melody, and used a strawberry flute for the vocals. For the accompaniment, I used an FM Grand piano, and as an accent, I brought in FM Tublers with ping-pong delay to create a sound exchange from the left and right. The production time was only five hours.
