How a 12-year-old's voice revolutionized electronic music in 1956
Seventy years ago, a groundbreaking electronic composition made its debut in Cologne. Karlheinz Stockhausen’s Gesang der Jünglinge stunned listeners with its radical sound and cryptic boy’s voice. The piece, performed on May 30, 1956, featured 12-year-old Josef Protschka, whose voice became central to the work.
The concert included seven new electronic works, but Gesang der Jünglinge stood out for its bold experimentation. Critics from Germany’s leading newspapers filled the WDR broadcast hall, where the studio had everything to prove. Josef Protschka was born in Prague in 1944 and raised in Düsseldorf. As a boy soprano, he sang in churches and at variety evenings at the Düsseldorf Opera. His talent caught Stockhausen’s attention, leading to a two-year collaboration.
For Gesang der Jünglinge, Protschka recorded atonal sine-wave sequences, his voice manipulated into something almost unrecognisable. The title, meaning Song of the Youths, referenced both the biblical story of three young men in a fiery furnace and the Holocaust. At its premiere, the piece baffled audiences—its technological novelty and abstract structure made it nearly impossible to follow.
When the performance ended, chaos erupted. Some listeners lunged at each other with umbrellas, overwhelmed by the piece’s intensity. Decades later, Protschka found deeper meaning in the work when it was performed at Cologne Cathedral in 2013. The 1956 premiere marked a turning point in electronic music. Protschka’s voice, preserved in Stockhausen’s composition, became part of a landmark in avant-garde sound. Today, Gesang der Jünglinge remains a defining work of its era, its legacy tied to both innovation and controversy.
