Miklós Kocsár wrote this work in 1993, commissioned by the artists Bea Berényi and her husband Ákos Dratsay. As the title indicates, the composer's intention was to display the tone and colour potential of the two flutes. The overall form of the work is provided by the sequence of eight sharply contrasting movements of differing length. The piece is characterized by thematic correspondences, variations, formal arcs that gradually reach completion, different styles of playing, alternating slow and fast musical materials, free and fixed rhythms, as well as cantabile and virtuosic sections.
