Iannis Xenakis - Mists

Mists, for piano (1981) Claude Helffer, piano Following the roiling, oceanic energy of Evryali (1973), Xenakis turned again to a watery image for his third piano solo, Mists (1980). Composed for Australian virtuoso Roger Woodward, Mists builds on principles from Evryali, adding a few new twists along the way. "Arborescences," dense, polyphonic bundles of melodies, are again prominent, here grouped into two different types. One is a "thicker" version of the sweeping waves of Evryali, with two or more layers shaping the contour rather than just one. The other opens out from the instrument's middle register, the contours taking shape in more sinewy and dendritic form. In both instances, Xenakis makes generous use of polyrhythms to distinguish the different strands within the texture: in certain passages, in fact, the pianist is asked to simultaneously manage four distinct rhythmic/temporal schemes. The other main texture Xenakis employs in Mists is a pointillistic one in which single notes are played in "haphazard" fashion to create a cloud of sounds; the range may either encompass the full register of the piano or be quite restricted, giving rise to recognizable motifs. Xenakis' notation, devised for this piece and employed extensively thereafter, provides a temporal/spatial grid within which the stemless notes are placed geometrically, the aim being to achieve a high degree of rhythmic accuracy without encumbering the performer with overly complex metric notation. Given that the temporal placement is generated from stochastic (probabilistic functions on a computer), absolute precision is not necessary (nor possible, in most cases). The piece is organized into three sections. The first contains the two kinds of arborescences; the second is entirely stochastic, employing the aforementioned "note clouds"; and the third is a sequence of alternations between the two types of material. There are also a number of silences that serve as a striking repose for the relentless onslaught of densely voiced musical gestures. These are not impressionistic "mists," but wind-driven, penetrating needles of urgent musical expression. [allmusic.com] Art by Hans Hartung
