Harlekin (1975) is one of the best known and most appreciated of Karlheinz Stockhausen‘s works for the originality of its mise-en-scène and mode of composition: the clarinettist, in fact, plays, mimes and dances contemporaneously. Stockhausen developed the concept of the composition for Formulas already tried in, among others, Mantra (1970) and Inori (1972).

The Formula, the extreme evolution of the post-Webernian series, is a collection of notes, dynamics, rhythms and detailed phrasing connected by close internal bonds balanced by precise mathematical calculations. Stockhausen’s Harlequin no longer possesses almost anything of the mask of the commedia dell’arte: the character that we see on stage does not express himself through the word but through music and body language. The pantomime, in its entirety, becomes an abstract representation of man’s life. The Formula of Harlekin consists of 13 sounds which evolve and are modified, in the space of 43 minutes, through seven sections, to which Stockhausen gives an exact title.

Michele Marelli (1978) is internationally recognised as one of the finest contemporary musicians of his generation. He collaborated with Karlheinz Stockhausen for more than 10 years, giving premières under his conductorship and recording 2 CDs with the Maestro himself. He has been Winner of the Stockhausen Stiftung für Musik (six times) and numerous other international awards; he collaborates, as clarinet and basset horn soloist, with the Ensemble Stockhausen, and is assistant to Suzanne Stephens at Stockhausen Kurse Kürten.

Harlekin was the last work prepared with the Maestro before his passing.
