The work consists of two movements, preceded by a short introduction and followed by an epilogue and a coda. It is played without a break. The first movement comprises three episodes, of which the first is the fastest, the second slower and the third is the slowest. The basic tempo remains the same and the differences of speed are realised by the lengthening of the rhythmical units. Each episode is followed by a short, slow intermezzo. It is based on a group of toccata-like themes contrasting with a rather singing one: a series of differentiated tuttis leads to a climax of the whole work. Then comes the last movement, based on a slow singing theme and a sequence of short dramatic recitatives played by the string group. A short and very fast coda ends the piece.
