  • Bellur, Ashwin; Ishwar, Vignesh; Serra, Xavier; Murthy, Hema A. (Universitat Pompeu Fabra, 2012)
    In this paper, we describe several techniques for detecting tonic pitch value in Indian classical music. In Indian music, the raga is the basic melodic framework and it is built on the tonic. Tonic detection is therefore ...
  • Sordo, Mohamed; Serrà Julià, Joan; Koduri, Gopala Krishna; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper a method for extracting semantic information from online music discussion forums is proposed. The semantic relations are inferred from the co-occurrence of musical concepts in forum posts, using network ...
  • Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    Our information technologies do not respond to the world's multicultural reality; in fact, we are imposing the paradigms of our market-driven western culture also on IT, thus facilitating the access of a small part of ...
  • Salamon, Justin; Gulati, Sankalp; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    The tonic is a fundamental concept in Indian classical music since it constitutes the base pitch from which a lead performer constructs the melodies, and accompanying instruments use it for tuning. This makes tonic ...
  • Sordo, Mohamed; Koduri, Gopala Krishna; Sentürk, Sertan; Gulati, Sankalp; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In the context of the CompMusic project we are developing methods to automatically describe/annotate audio music recordings pertaining to various music cultures. As a way to demonstrate the usefulness of the methods we ...
  • Font, Frederic; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    User generated content shared in online communities is often described using collaborative tagging systems where users assign labels to content resources. As a result, a folksonomy emerges that relates a number of tags ...
  • Sentürk, Sertan; Holzapfel, Andre; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    The main information sources to study a particular piece of music are symbolic scores and audio recordings. These are complementary representations of the piece and it is very useful to have a proper linking between the ...
  • Serrà Julià, Joan; Koduri, Gopala Krishna; Miron, Marius; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    The issue of tuning in Indian classical music has been, historically, a matter of theoretical debate. In this paper, we study its contemporary practice in sung performances of Carnatic and Hindustani music following an ...
  • Gulati, Sankalp; Salamon, Justin; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper we propose a new approach for tonic identification in Indian art music and present a proposal for a complete iterative system for the same. Our method splits the task of tonic pitch identification into two ...
  • Özaslan, Tan Hakan; Serra, Xavier; Arcos Rossell, Josep Lluís (International Society for Music Information Retrieval (ISMIR), 2012)
    The embellishments of makam music in Turkey are an inherent characteristic of the music rather than a separate expressive resource, thus their understanding is essential to characterize this music. We do a computational ...
  • Koduri, Gopala Krishna; Serrà Julià, Joan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    Intonation is an important concept in Carnatic music that is characteristic of a raaga, and intrinsic to the musical expression of a performer. In this paper we approach the description of intonation from a computational ...
  • Koduri, Gopala Krishna; Serrà Julià, Joan; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of the rāga and intrinsic to the musical expression of the performer. Describing intonation is of importance ...
  • Font, Frederic; Roma, Gerard; Herrera Boyer, Perfecto; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    There are many online communities with membergenerated and openly available multimedia content. Their success depends on having active contributing users and on producing useful content. With this criterion, the community ...
  • Serrà Julià, Joan; Gómez Gutiérrez, Emilia; Herrera Boyer, Perfecto; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We present a new technique for audio signal comparison based on tonal subsequence alignment and its application to detect cover versions (i.e., different performances of the same underlying musical piece). Cover song ...
  • Koduri, Gopala Krishna; Miron, Marius; Serrà Julià, Joan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    The classical music traditions of the Indian subcontinent, Hindustani and Carnatic, offer an excellent ground on which to test the limitations of current music information research approaches. At the same time, studies ...
  • Serrà Julià, Joan; Serra, Xavier; Andrzejak, Ralph Gregor (Institute of Physics (IOP), 2009)
    There is growing evidence that nonlinear time series analysis techniques can be used to successfully characterize, classify, or process signals derived from realworld dynamics even though these are not necessarily deterministic ...
  • Maestre Gómez, Esteban; Ramírez, Rafael; Kersten, Stefan; Serra, Xavier (MIT Press, 2009)
    Here we describe an approach to the expressive synthesis of jazz saxophone melodies that reuses audio recordings and carefully concatenates note samples. The aim is to generate an expressive audio sequence from the analysis ...
  • Sordo, Mohamed; Serrà Julià, Joan; Koduri, Gopala Krishna; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    By mining user-generated text content we can obtain musicrelated information that could not otherwise be extracted from audio signals or symbolic score representations. In this paper we propose a methodology for ...
  • Font, Frederic; Serrà Julià, Joan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    Collaborative tagging has emerged as an efficient way to semantically describe online resources shared by a community of users. However, tag descriptions present some drawbacks such as tag scarcity or concept ...
  • Akkermans, Vincent; Font, Frederic; Funollet, Jordi; de Jong, Bram; Roma, Gerard; Togias, Stelios; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    Freesound.org is an online collaborative sound database where people from different disciplines share recorded sound clips under Creative Commons licenses. It was started in 2005 and it is being further developed by the ...
