"Subimago": Stage of development of the winged but still not sexually mature ephemera (Duden – dictionary).
*
Subimago is the attempt to represent the development process of a two-relationship, whose participants are impersonated by viola and piano. The isolationist existence of every actor gives way to the search for each other. Only gradually succeeds that thematic material belongs to both, that’s why understanding and communication become possible. What began as a harsh against each other, ends in a fusion which has already left the ecstasy behind.
