Jennifer Stasack, Crossing Rivers IV, Mvt.
4, mm. 6-8
piano part of Movement IV of Crossing Rivers IV requires the pianist to
play white-key note clusters with the palms of the hand and black-key note
clusters with completely flat fingers (no tips). This is indicated at the
beginning of the movement over the first four clusters. Black-key and white-key
clusters are clearly indicated in the score by the placement of sharps
or flats next to every note within a given cluster, or by placing no sharps
or flats next to others. Stasack has mentioned that one need not hit the
exact notes indicated in the score, but the important thing, according
to her, is to follow the shape and dynamics of each short phrase, as well
as the general range on the keyboard of each cluster. The hand is flat
in shape and makes a crawling motion up or down the keyboard, following
the direction of each phrase. In order for there to be legato connection
between each cluster, the hand needs to be flexible.
