Anatom was one of the early pieces written using the Raku Composition Program (RCP) developed by Dan Senn initially at the Canberra School of Music in Australia in 1981. The orginal work, called Might Nots, from whence this work was derived, was composed for two pianos and written 1983-84 in Canberra. Then, in 1996, after the death of Dan's friend and teacher Salvatore Martirano (November, 1995), he reworked the original score and composed Anatom for Sal. In 2015, in his Watertown Studio, he again updated the piece as presented here.
The RCP, produces of a variety of stylistic artifacts (see Its Mirror for solo flute) and is used in this work to create a continuum of driving and kaliedoscopic modalities resting beneath a 5/5 metrical net which captures the piece for live performance. Yet perception of the piece may exist apart from its surface structure, i.e., phrases which trigger tonal (chance) references to musical memory, can begin at any point. This happens because the RCP processes data cell-by-cell, 120 in all, and the 5/4 netting is simply plopped on top like fencing over hilly country land.
The reference to the earth and geography here is central to understanding the RCP as the software arose out of Senn's close association with ceramic art, specifically the Raku process, and with the land itself having spent much of his youth farming, gardening and camping throughout the western United States. Musical material, in the RCP, is treated plastically and like layers of earth strata which can be stretched, displaced, driven upward and condensed.
