A Multi-Layered, Time-Based Music Description Approach Based on XML

Advanced interfaces for music enjoyment

“…This structure has been proposed and studied in [3]. Each layer aims at describing a music piece from a different and complementary perspective.…”

Music Description and Processing: An Approach Based on Petri Nets and XML

“…According to the definition in (Haus & Rodriguez, 1993), a music object may be anything that could have a music meaning and that could be thought as an entity, either simple or complex, either abstract or detailed. Such entity will present some relationship with other music objects.…”

“…It must be noted that different applications of Petri Nets to music analysis lead to apparently contradictory results. While Ravel's Bolero structure has been very well described in a convenient series of models (Haus & Rodriguez, 1993), some limitations of this approach have become evident when trying to describe, for example, the complexity of Stravinsky's Rite of Spring (De Matteis & Haus, 1996). From the analytical perspective, excellent or poor results in representing music analysis through Petri Nets formalism mainly depend on three factors: 1.…”

“…The main purpose of this format is having a comprehensive description of music (Haus & Longari, 2005). Even if specific encoding formats that represent peculiar music features, such as audio tracks or scores, are already commonly accepted and in use, they are not conceived to encode all this features together.…”

An XML-based Synchronization of Audio and Graphical Representations of Music Scores

“…2 This recommended practice deals with applications and representations of Symbolic Music Information using the XML language, as described in [1]. The proposed IEEE PAR1599 comes at a point in time when it is possible to draw from the experience of existing, previous efforts.…”
