“Fragment d‘une ébauche” is a very short piano work which Pierre Boulez dedicated to Jean-Marie Lehn in 1987 on the occasion of his Nobel Prize in Chemistry. Jean-Marie Lehn held the chair of chemistry at the Collège de France while Pierre Boulez gave lectures in invention, technique and language of music. A friendship connected the two persons.
Pierre Boulez dedicated this piece to Jean-Marie Lehn and wrote on the score: ‘The fragment of a future work for piano and instrumental ensemble, still in draft form. But for a Nobel Prize winner, one can make an exception and give a simple draft as a token of sympathy and admiration.’
