Gesang der Jünglinge "complexes" structured statistically . The last category occurs in Stockhausen's electronic music for the first time in "Gesang der Jünglinge", and originates in the course of studies Stockhausen took between 1954 and 1956 with Werner Meyer-Eppler at the University of Bonn. The text of "Gesang der Jünglinge" is from a Biblical story in The Book of Daniel where Nebuchadnezzar throws Shadrach, Meshach, and Abednego into a fiery furnace but miraculously they are unharmed and begin to sing praises to God. This text is presented in a carefully devised scale of seven degrees of comprehensibility, an idea which also came from
Shadrach, Meshach, and Abednego to in odes seven and eight of the canon, a hymn sung in the matins service and on other occasions in the Eastern Orthodox Church, where their feast day is December 17 (along with Daniel). The Orthodox also commemorate them on the two Sundays before the Nativity of Christ. The reading of the story of the fiery furnace, including the song, is prescribed for the vesperal Divine Liturgy celebrated by the Orthodox on Holy Saturday. Likewise, the three are commemorated as prophets in the Calendar of Saints of the Lutheran Church on December 17 with Daniel. Musical Christy Semsen and
