Like all of Hauke Harder's chamber music, Pure Presence involves a small number of fixed pitches
that are projected in simple patterns onto a steady pulse or metrical field. Harder notates
superficially simple figures that bring out an acoustical illusion space through interference
and combination tones and other acoustical phenomena. The narrow gamut of pitches and the repeated
rhythms are points of reference from which the listener can orient her attentions.
The rhythmic patterns are not developed, but rather begin and end abruptly without logical or
rhetorical motivation. Likewise, Hauke chooses his pitches on the basis of their transparence --
and their potential disappearance into the overall gestalt. In his most recent compositions,
this transparence is created by taking pitches which relate to one another as do the partial
tones in a harmonic series...
