The titleThe incommunicability between different cultures and worlds and the confusion that this generates lie at the heart of this work: the fanfare-like themes that characterise the introduction, together with the "Arabian" melodies of the Presto, represent these differences. The bare theme of the Andante, while offering a glimpse of hope, also describes the impossibility of a meeting and the pain this situation causes. The empty fifth and dissonance of the minor second are elements that feature throughout this work. In the Coda, moreover, all these ideas reappear "kaleidoscopically", amidst a convulsive and excitingly chaotic atmosphere.
