Abstract

The publish/subscribe messaging model is widely used within distributed business systems as a scalable delivery mechanism for business events. More recently, implementations have been developed for more compact messages such as those used for instrumentation applications.This talk describes a music analysis framework implemented in Java consisting of applications linked by an event distribution mechanism using a publish/subscribe message broker. Using the framework, applications can be developed that take advantage of the messaging properties that decouple space, time and synchronisation between publishing and subscribing applications. The use of the framework is illustrated by describing the support for MIDI messages and applications for pitch spelling using the spiral array, visualisation and building semantic networks. A comparison is made between the results obtained with a modified spiral array spelling algorithm with previously published set. A demonstration ontology for representing the semantic relationship between the musical concepts extracted during the analysis is defined.
