PAULINE OLIVEROS' TRIO for flute, piano, and page turner (1961) unfolds, without pretension, as a dramatic and unrestrained gesture through simple materials that are handled in such a manner that even the work's most complex events are clearly comprehensible. The flute and piano are treated with great care for their unique qualities, while the page turner's integral role is to prepare sounds for the pianist. Although the instrumental materials are for the most part characteristic, there is at times an interrelation that projects a new sound; for example, the piano occasionally acts as an attack for the flute tone, and elsewhere, the flute emerges from the harmonics or prepared piano sounds, creating an effect of continuum. Similarly, quarter tones are utilized not in a structural manner but as an intensification of individual pitches.
