Nuances is a composition in two parts. These parts differ tonally not only in that flute is used in the first movement and alto flute in the second, but also in the different instrumentation in the percussion. In the first part, woodwinds and drums dominate, i.e. instruments with short sound duration. The musical development is strongly rhythmically oriented, melodic motif chains in the flute are varied in several ways. Three virtuoso interpolations by the flute interrupt the largely rigid musical flow. The second movement is dominated by metal instruments, some with long decay times, and the timbres become more important. Here, too, individual motif bits of the flute part are constantly varied and recombined.
