A centralized access to sources, editions, and further kinds of publications facilitates the research process and provides a comprehensive overview of existing information. To connect musicological collections and repositories, we created a metasearch for annotated music: IncipitSearch. It is a tool and a service specifically tailored for research on music incipits, the initial sequences of notes that characterize a work. IncipitSearch is a service to interconnect musical pieces via metadata. It is also a tool that can be reintegrated into existing digital research platforms. By connecting some of the largest digital collections of music metadata it already offers access to around 1 million incipits. In four comprehensible steps, this poster will be a guide explaining how data owners can add their data to IncipitSearch and how the reimplementation of the search functionality can be carried out.
