Music linked with geography and moods

Group Music Technology (GTM) and DJ Melbourne at Pompeu Fabra (UPF) presented these days its new research projects at the International Conference on Music Information Retrieval 2009 (ISMIR 2009), held in Kobe (Japan) to the 30th of October.

GTM’s contribution consists of nine -three oral communications and posters-six, five shows seven contributions to the community sessions Music Information Retrieval Evaluation eXchange (MIREX), plus a special session.

Researchers at GTM , Emilia Gomez Haro and Martin Perfecto Herrera, are the authors of the paper in the ISMIR 2009 : Music and geography: description of musical audio content from different parts of the world . The paper analyzes 6,000 pieces of music from around the world from different geographical areas and compares both their common features as that differentiate them . Automatic description of audio signals, together with data mining techniques provide useful means for comparative analysis and classification of music from around the world, and provide an original link between music and geography.

Meanwhile, Cyril Laurier, Mohamed Sordo, Juan Serrano and Perfecto Herrera, researchers GTM are the authors of the communication Music Mood Representations from Social Tags , and study the relationship between the ways to describe moods that uses a community listeners and descriptors used by academic researchers. This knowledge becomes a fundamental part of algorithms and computational models used for automatic classification of songs according to the mood. The paper identifies basic models of emotions and classified into four possible states of mood: happy, sad, angry and sensitive.

Characterization of musical instruments

In Scalability, generality and temporal aspects in automatic recognition of musical predominant instruments in polyphonic music , by Ferdinand Fuhrmann, Martin Haro and Perfecto Herrera, a classification polyphonic audio is presented for different types of musical instruments that includes methodological aspects often little studied. The work aims to provide a unified platform to extract each track the information needed to build computational models to determine what instruments sound with no prominence.

In addition, several members of GTM, led by Xavier Serra, promoter and director of the research group, the future of musical recovery technologies arises.

The GTM was created in 1994 by its current director, Xavier Serra. It is integrated within the Department of Information Technology and Communications and the Institut Universitari de l’Audiovisual , specializing in digital technologies related to sound and music, with more than 40 researchers from different and complementary areas.

Last year the UPF initiated the Master in Sound and Music , an official master whose program provides advanced training in a wide range of disciplines ranging from engineering to musicology, through computing, acoustics, electronics the musical composition or psychology. The master is oriented towards two aspects, professional and research, with the main objective of training professionals and prepared to work in the field of music technology and sound in the context of the current information society researchers.
