According to the Encyclopaedia Britannica, the Ancient Greek term mīmēsis, derived from mīmeisthai (μιμεῖσθαι, ‘to imitate’) is a “basic theoretical principle in the creation of art” and may be defined as “‘imitation’ (though in the sense of ‘re-presentation’ rather than of ‘copying’).” Greek philosopher and polymath Aristotle (384-322 BCE) regarded mīmēsis as the imitation of nature, with its enactment of perfection achieved via a consideration of the four causes in nature (material, formal, efficient or agent, and final or purpose) in tandem with the aesthetic quality of beauty, framed by the mathematical sciences around “order and symmetry and definiteness.” The work adopts a unique interpretation of the concept of mimesis via the juxtaposition of ‘organic,’ or intuitively-driven invention with algorithmic composition based on ‘probabilistic automata’. The melodic elements of the viola part exclusive to the former, while the materials for the secondary tape element – represented by the Virtual Nagoya Harp, or Taishãgoto (a rectangular-shaped wooden zither invented in 1912 in Nagoya, Japan by Nisaburo Kawaguchi ‘Gorã Morita’ featuring the mechanics of a typewriter with a traditional koto or autoharp) – entirely generated by a set of algorithms that ‘imitate’ the primary source via Markov-chain-derived modelling, or algorithmic mapping of the melody that take into account every set of transitions between the states. The rhythm adopts the combinatorial strategy of ‘Single-State Probabilistic Automatons,’ or “unrestricted compositions of the integer n into m parts.” The viola on the other hand incorporates a rhythmic structure based on the exploration of the mathematical concept of ‘partitions’ or ‘all partitions of n with m parts in the set’, subdividing all 20-second intervals of the work into a varied number of parts and sizes that symmetrically expand and contract in rhythmic density (essentially metric modulations with the ratios 1:1, 3:2, 2:1, 3:1, 2:1 and 3:2) over an arch-form structure.
