“At the request of the work's commissioner, Heinz Holliger, this duet has very few passages that call for 'unconventional' performance techniques. In exchange, it exploits the many musical possibilities opened up by two instruments with closely related timbres: wide-ranging antitheses and commonalities of expression and movement, cantabile duets, convergences in unisons, octaves and fifths.”<br>
