    Abstract

    ![CDATA[The coordinated storage of performance data in such a way that it can be used across multiple projects is problematic: general purpose systems that can store gestural, score, and other performance data are not generally available. Using data from current projects, we aim to provide a unified database that can store and present a musical score alongside associated performance data and musical analysis. Using a general purpose representation language, Performance Markup Language (PML), aspects of performance are recorded and analyzed. Data thus acquired from one project is made available to others. Presentation involves highquality scores suitably annotated with the requested information. Such output is easily and directly accessible to musicians, performance scientists, and analysts. We define a set of data structures and operators that can operate on musical pitch and musical time, and use them to form the basis of a query language for a musical database. The database can store musical information (score, gestural data, etc.) and audio/video artifacts. Querying the database results in annotations of the musical score, potentially augmented with audio/video selected from stored performances. Two demonstrations are provided: an analytically-based query and a performance-gesture-based one. In the former, dissonant notes/intervals are identified in a performance of a Bach two-part invention. The score is then graphically annotated to indicate the performers’ mean inter-onset intervals in the neighborhood of these features. In the latter, a score of a 19-ET microtonal song is displayed, annotated with the deviation in the soprano’s pitch from that notated. The database is capable of storing musical score information and multimedia recordings and cross-referencing them. It is equipped with the necessary primitives to execute music-analytical queries, and highlight notes identified from the score.]]
