Talk concert with pianist Claudia Janet Birkholz
Guest: Heinz-Otto Peitgen, mathematician
With works by György Ligeti (1923-2006)
as well as pictures of fractal geometry
Music releases numerous feelings in most people. If there are patterns behind what is heard, they can trigger a maelstrom-like effect.
In her discussion concerts, Claudia Janet Birkholz, pianist and artistic director of the realtime Festival for New Music, invites people to the Weserburg Museum of Modern Art in Bremen three times a year.
On May 12, beginning at 7 p.m., she and her guest, the mathematician Heinz-Otto Peitgen, will talk about illusory patterns in connection with fractal geometry. In the process, she will play selected pieces by György Ligeti, in which it will become clear how music can make use of these patterns and trigger special perceptions. Baffled, the audience wonders: How many hands are playing the piece? How wide is the keyboard?
Ligeti himself takes center stage, as does the parallelism between the mathematical research and his own compositional aspirations. When Ligeti saw Heinz-Otto Peitgen’s computer representations of the Mandelbrot set beginning in the 1980s, he understood the connection.
Birkholz and Peitgen talk about fractal geometry, the effect of supersignals, and the fascinating pull that certain music can have – played by Claudia Janet Birkholz on the grand piano.
Heinz-Otto Peitgen was professor of mathematics at the University of Bremen (emeritus in 2012) and president and CEO of Jacobs University in 2013.
Claudia Janet Birkholz is a pianist and lecturer for piano and new music at the HfK in Bremen.
