Dancing tango. A stage, a black curtain, a nothing, a something. More? Music. The couple dancing tango finds its analogy in the two clarinets. The dancers are moving on a fictitious stage - different constellations develop in this room, various relationships between the instruments come into being. The thirteen minute tangos trace these different constellations. They create miniature pictures of the situations, sketches, each of them with an approximate duration of one minute, grouped into two units of six minute tangos each and rounded off with the somewhat longer 'Canción'. Two people are dancing tango. Two instruments are playing for the dance.
