Scale transformations, the interpenetration of macro and micro dimensions, are part of the serial fabric of Stockhausen's work. This is a composer who compresses rhythm into pitch in Kontakte and slows down the sound of geese until they are revealed as the shouts of a football crowd in Hymnen. If I am right and the violin is a mosquito, then what the composer is also saying is that the mosquito is also a tiny helicopter. The violin is the connection. There is a deep poignancy here.
Children play and squeal, a distant ship's horn sounds.
The nervous fidgeting of the solo players is offset by tape images evoking the stained glass and movie screens that to a poor kid in Nazi Germany were windows to a better life and represented a higher truth than the wretched reality of despair and deprivation he endured as a child.
