S Ori 70, also known as S Ori J053810.1–023626, takes its name from a mid-T type astronomical object located about 1,150 light-years from Earth — an enigmatic body discovered in 2002 by M. R. Zapatero-Osorio and E. L. Martín’s team at the Roque de los Muchachos Observatory (La Palma). There remains ongoing debate over whether it is a field brown dwarf or a young planet belonging to the σ Orionis cluster — perhaps even one of the first known free-floating planets.
This is the first piece in which the Mini-Fan technique is used, allowing the creation of sustained drones inside the piano and enabling complex transitions across the harmonic series and between the series and the string’s fundamental. The work explores the piano as a polyphonic and spatial instrument — unstable and elusive.
