Well, it will be difficult. It is a youthful piece that Boulez has always rejected from the official catalogue of his works. In consequence, I don't think the score has ever been published. If you truly want the sheet music, your only hope would be to contact the Paul Sacher Stiftung or the Bibliothèque nationale de France, who share the Pierre Boulez archives, to see if they can provide it to you.

Where can I find the sheet music...
