“[A]fter absorbing lessons from visiting volunteer luthiers and a three-month apprenticeship in Italy, Mr. Shelaldeh, 18, has his own instrument repair shop. It is in a former garage around the corner from the [Ramallah] music center, Al Kamandjati (‘the Violinist’). He has learned to fix instruments and replace the hair on bows. He has already made two violins, one with a tiny Palestinian flag on the tailpiece, which anchors the strings.”
