Fusion, for twelve instrumentalists, proposes to illustrate a writing process that will be further developed in successive works (Transmutations). Two ideas are exposed, at first differentiated, that discontinuously fuse.
One of the elements is serialized, the other is not. The influences these two materials exert upon each other are not caused by one (or several) of these instrument(s), but are organized according to the general distribution of all of the twelve instruments in the ensemble with some digressions. The experience of the listener is, therefore, sometimes analytical, sometimes global.
