The piece starts with the introduction of all four instruments, one by one. Throughout the piece the instruments relate to each other; sometimes play rhythmically together in different combinations , sometimes their rhythms are independent.
At the beginning the texture is rather complex. Gradually it becomes more and more simple and towards the end 3 instruments play in rhythmic unison and only the piano keeps its independence.
The lyrical parts serve as a contrast to the continuous rhythmical flow of the piece.
