Abstract
AbstractIn order to perform with consistency a musical score having multiple parts, as in an orchestra or a chorus, it is important that the conductor and performers share its musical semantic structures. However, past studies of the expression or visualization of musical semantic structure in the field of music information processing have dealt with scores having a single voice part. In this paper, we propose a new electronic musical score system, “HyperScore,” based on the hypertext data model. Expanding the hypertext data model and its visualization mechanism, HyperScore has a flexible semantic structure model and a strong visualization mechanism which help the conductor and performers understand the semantics of the score and communicate with each other. The musical semantic structure model consists of three components: phrase–motif–note tree structures of the musical score, musical structures such as particular musical forms, and links among these structures. The visualization mechanism generates various views of the semantic structure of the music from different perspectives. The view is generated by a visualization mechanism specifying four parameters: the XY axes, display rules, selection, and granularity. The view illustrates the musical semantics of series of notes clearly by their position in the view and their display attributes. © 2001 Scripta Technica, Syst Comp Jpn, 32(7): 39–51, 2001
