The paper presents definition extensions to MPEG-7 metadata ones, mainly related to audio descriptors, introduced to efficiently describe traditional Greek music data features in order to further enable efficient music retrieval. A number of advanced content-based retrieval scenarios have been defined such as query by music rhythm, query by example and humming based on newly introduced music features, query by traditional Greek music genre, chroma-based query. MPEG-7 DDL extensions and appropriate traditional greek music genre dictionary entries are deemed necessary for accounting for the specificities of the music data under question and for attaining efficiency in music information retrieval. The reported work has been undertaken within the framework of an R&D project targeting an advanced music portal offering a number of content-based music retrieval services, namely POLYMNIA [12].
