The title SLF is defined twice: The "superior longitudinal fasciculus" is a bundle of nerves in the brain. This combines the sensory Wernicke center, whose function is the semantic processing of speech, with the Broca center, which controls the motor skills of speech as well as syntactic speech processing.
"City - Country - River" (in German: "Stadt - Land - Fluss" = SLF) overrides the three movements. The text content consists of geographic terms, cities, countries and rivers (with some distractions). At the same time, the individual movements rhythmically-motorically and sonically-formally characterize the three places in their respective relationships and meanings for human being.
The first movement "city" consists of city names of different density and relatively fast tempo spoken in different pitches. Predominantly contrapuntal, the voices coordinate at various points in a brief, concise, homophonic phase, only to separate again. Structurally, the bass voice gives a continuous meter of monosyllabic city names and descending lines.
The second movement "country" is quiet and tender and consists mainly of slowly changing reclining sounds, in which - in two voices - the country names appear.
The third movement consists of a contrapuntal network of river names moving in small melismas. The individual voices each use their own diatonic tone reservoirs, so that a polytonal mesh is created.
