Sevenminute-Play for flute and piano
Sevenminute-Play for flute and piano
Rudolf Kelterborn: Sevenminute-Play for flute and piano was written in 1976. The piece was premiered on February 20, 1977, in New York by the renowned Swiss flutist Aurèle Nicolet and pianist Jürg Wyttenbach.
As the title suggests, the work is strictly timed, exploring the tension between "clock time" and "musical time." The composition is categorized as a "dialogue" piece where the flute and piano act as dramatic antagonists or partners in a compressed seven-minute span.
At the time of composition, Kelterborn was interested in the tension between perceived duration (how long a listener feels a piece is) and chronological duration. By titling it after its length, he creates a psychological "countdown" for the audience, forcing them to be aware of the passage of time as an active element of the performance.
In the German musical tradition (Spiel), the word "Play" carries two meanings that Kelterborn exploited.
The piece is a theatrical interaction where the instruments are "players" in a drama, often acting as antagonists or mimics of one another. By calling it a "Play" rather than a "Sonata" or "Suite," Kelterborn was signaling his mid-70s shift away from rigid serialism. He wanted the work to feel improvisatory and "played," despite its strict seven-minute structure.
From 1975, Kelterborn Held a position as Director of the Basel Academy of Music. His administrative duties limited his time for massive orchestral works. The "Sevenminute" title reflects his new artistic goal in 1976: to pack the maximum emotional tension of an opera into a miniature timeframe. The title also honors the technical "playfulness" of Aurèle Nicolet, the flutist for whom it was written. Nicolet was known for his ability to handle rapid, "pointillistic" character shifts, which the title Sevenminute-Play captures.

Sevenminute-Play
Kelterborn Rudolf
Rudolf Kelterborn (1931–2021) was a Swiss composer, conductor, and educator, regarded as one of the most influential figures in 20th-century Swiss musical life. His style is noted for its rigorous structural integrity and expressive, often dramatic, tonal language.
Born in Basel, Switzerland, he grew up in a city with a deep intellectual and musical heritage. He studied at the Basel Academy of Music, focusing on composition, conducting, and music theory.
His upbringing was shaped by studies with Walther Geiser (a student of Busoni) and Willy Burkhard in Zurich. He later moved to Germany to study with Boris Blacher and Wolfgang Fortner, whose influence helped bridge Kelterborn's traditional roots with the emerging avant-garde.
Kelterborn's career is characterized by a rare balance of high-level administration and prolific création.
He served as the Director of the Basel Academy of Music (1975–1983), where he oversaw the training of a generation of European modernists. Before that, he was the head of the music department for Swiss German Radio (DRS) for five years. A role that allowed him to champion contemporary music on a national scale.
Early in his career, Kelterborn was associated with serialism and the strict structuralism of the Darmstadt school. However, by the 1970s (around the time of Sevenminute-Play), his work became more gestural and intuitive, prioritizing psychological tension over mathematical systems.
