The paper addresses issues related to the design of query languages for searching and restructuring collections of XML-encoded music scores. We advocate against a direct approach based on XQuery, and propose a more powerful strategy that first extracts a structured representation of music notation from score encodings, and then manipulates this representation in closed form with dedicated operators. The paper exposes the content model, the resulting language, and describes our implementation on top of a large Digital Score Library (DSL).
