Gesang der Jünglinge

Gesang der Jünglinge (literally "Song of the Youths") is an electronic music work by Karlheinz Stockhausen. It was realized in 1955–56 at the Westdeutscher Rundfunk studio in Cologne and is Work Number 8 in the composer's catalog. The vocal parts were supplied by 12-year-old Josef Protschka. It is exactly 13 minutes, 14 seconds long.

The work, normally described as "the first masterpiece of electronic music" and "an opus, in the most emphatic sense of the term", is significant in that it seamlessly integrates electronic sounds with the human voice by means of matching voice resonances with pitch and creating sounds of phonemes electronically. In this way, for the first time ever it successfully brought together the two opposing worlds of the purely electronically generated German elektronische Musik and the French musique concrète, which transforms recordings of acoustical events. Gesang der Jünglinge is also noted for its early use of spatiality; it was originally in five-channel sound, which was later reduced to just four channels (mixed to monaural and later to stereo for commercial recording release).
