In 1975, Stockhausen wrote twelve little pieces, one about each of the signs of the Zodiac.Those twelve little melodies, written initially for twelve music boxes, were among the instrumental building stones of another work, Musik im Bauch (Music in the Belly), which also involved six percussionists and a sound projectionist. It was only later that Stockhausen decided to reuse these twelve pieces and to turn them into an autonomous work. On that occasion, he also edited a score of the work under the title Tierkreis. Among the recordings of the piece already available, this new version by Het Collectief and Capilla Flamenca, going under the name “12x12”, strikes us by its originality. In their approach, Stockhausen’s little music pieces are extended and further elaborated, they even quote in a daring but most successful way some 14th century compositions, more specifically from the Ars Nova period, as point of reference. The confrontation, but in a certain sense also the symbiosis between these radically opposed worlds, plunges the listener from the first musical notes into a very special poetic universe.
