Co-incidence is a work that opens onto an anacrusi made of two notes, the main element of everything that will happen. These first two notes falling like two short blasts thrown into space will evolve in a more and more resolute manner. The bass string of the violin is tuned to the notes ''E'' instead of ''G'', giving the instrument a close to the Viola range, and allowing the creation of an atmosphere of a dark and dramatic lyricism, interrupted by a new theme ''Presto'' and light, that we will find again at the lightning conclusion.
