Seminario sobre Cante Flamenco y Música Andalusí
16 Oct 2013

El miercoles 16 de Octubre a las 15:00h en la sala 55.309 del Campus de la Comunicación de la UPF tendremos una conferencia sobre el Cante Flamenco, impartida por José Miguel Díaz-Báñez y Joaquin Mora (Universidad de Sevilla) y otra sobre la Música Andalusí impartida por Amin Chaachoo (Tetouan-Asmir Center).

"Apuntes sobre el Cante Flamenco. El Caso de las Tonás"
José Miguel Díaz-Báñez y Joaquin Mora (Universidad de Sevilla)
Esta charla pretende ofrecer una introducción al cante flamenco pasando de lo general a lo particular, describiendo los aspectos generales que se requieren para realizar una incursión en el marco del flamenco y particularizando después en un grupo de "cantes",  conocidos como  "cantes por tonás", que se interpretan a capela y poseen una riqueza ornamental heredada de la cultura mediterránea.
"La Música Andalusí. Historia, Identidad y Características"
Amin Chaachoo (Tetouan-Asmir Center)
Se la conoce como Música andalusí, o Al-Ala, o Música Hispano-Musulmana o Música Arábigo-Andaluza. Se la define como la Música de Al-Ándalus, el patrimonio musical que los andalusíes descendientes de los expulsados de la península ibérica, conservaron y trasmitieron con cariño, amor, y sobretodo, con orgullo. Pero ¿cómo fue esa música? ¿Cómo se desarrolló en la Península? ¿Cómo llegó a ser una de las músicas más ricas y complejas? ¿Qué influencias y aportes contribuyeron en su formación? ¿Y cuál fue su destino en los países de acogida de los andalusíes?
Todas estas preguntas serán tratadas por Amin Chaachoo en la charla titulada “LA MÚSICA ANDALUSÍ. HISTORIA, IDENTIDAD Y CARACTERÍSTICAS” y que tratará de los distintos aspectos de esta música: sus componentes históricas, las fases de su desarrollo, su repertorio, sus tendencias, sus modos musicales, sus orquestas, etc. La conferencia incluirá además proyecciones de vídeo y audiciones de grabaciones que manifiestan y dejan ver la verdadera identidad de la música andalusí.

Justin Salamon defends his PhD thesis
20 Sep 2013

Justin Salamon defends his PhD thesis entitled "Melody Extraction from Polyphonic Music Signals" on Friday 20th of September 2013 at 10:00h in room 55.390.

The jury members of the defense are: Geoffroy Peeters (IRCAM), Fabien Gouyon (INESC-Porto), Juan Bello (NYU).

Abstract:  Music was the first mass-market industry to be completely restructured by digital technology, and today we can have access to thousands of tracks stored locally on our smartphone and millions of tracks through cloud-based music services. Given the vast quantity of music at our fingertips, we now require novel ways of describing, indexing, searching and interacting with musical content. In this thesis we focus on a technology that opens the door to a wide range of such applications: automatically estimating the pitch sequence of the melody directly from the audio signal of a polyphonic music recording, also referred to as melody extraction. Whilst identifying the pitch of the melody is something human listeners can do quite well, doing this automatically is highly challenging. We present a novel method for melody extraction based on the tracking and characterisation of the pitch contours that form the melodic line of a piece. We show how different contour characteristics can be exploited in combination with auditory streaming cues to identify the melody out of all the pitch content in a music recording using both heuristic and model-based approaches. The performance of our method is assessed in an international evaluation campaign where it is shown to obtain state-of-the-art results. In fact, it achieves the highest mean overall accuracy obtained by any algorithm that has participated in the campaign to date. We demonstrate the applicability of our method both for research and end-user applications by developing systems that exploit the extracted melody pitch sequence for similarity-based music retrieval (version identification and query-by-humming), genre classification, automatic transcription and computational music analysis. The thesis also provides a comprehensive comparative analysis and review of the current state-of-the-art in melody extraction and a first of its kind analysis of melody extraction evaluation methodology.

ONA, a catalan virtual singer at La Mercè
20 Sep 2013 - 24 Sep 2013

This week the first catalan virtual singer ONA will perform at Parc de la Ciutadella for the festivities of the saint patron of Barcelona (La Mercè). She will sing and dance together with other virtual singers (Bruno & Clara). People from the audience can get to the stage and control the performance of the virtual characters live using a kinect sensor. In addition, Ona will sing short poems selected from the tweets sent with hash tags #OnaEstiu #OnaFesta #OnaCiutat and #OnaFutur, which correspond to summer, party, city and future subjects.

Voctro Labs is preparing the concert and providing the virtual singers. You can check the following link for more details (in catalan).

José R. Zapata defends his PhD thesis

José R. Zapata defends his PhD thesis entitled "Comparative Evaluation and Combination of Automatic Rhythm Description Systems" on Thursday 19th of September 2013 at 16:00h in room 55.410.

The jury members of the defense are: Fabien Gouyon (INESC-Porto), Juan Bello (NYU), Xavier Serra (UPF).

Abstract: The automatic analysis of musical rhythm from audio, and more specifically tempo and beat tracking, is one of the fundamental open research problems in Music Information Retrieval (MIR) research. Automatic beat tracking is a valuable tool for the solution of other MIR problems, as it enables beat-synchronous analysis of music for tasks such as: structural segmentation, chord detection, music similarity, cover song detection, automatic remixing and interactive music systems. Even though automatic rhythm description is a relatively mature research topic in MIR and various algorithms have been proposed, tempo estimation and beat tracking remain an unsolved problem. Recent comparative studies of automatic rhythm description systems suggest there has been little improvement in the state of the art over the last few years. In this thesis, we describe a new method for the extraction of beat times with a confidence value from music audio, based on the measurement of mutual agreement between a committee of beat tracking systems. Additionally, we present an open source variant of the approach which only requires a single beat tracking model and uses multiple onset detection functions for the mutual agreement. The method can also be used identify music samples that are challenging for beat tracking without the need for ground truth annotations. Using the proposed method, we compile a new dataset that consists of pieces that are dicult for state-of-the-art beat tracking algorithms. Through an international evaluation framework we show that our method yields the highest AMLc and AMLt accuracies obtained in this evaluation to date. Moreover, we compare our method to 20 reference systems using the largest existing annotated dataset for beat tracking and show that it outperforms all the other systems under all the evaluation criteria used. In the thesis we also conduct an extensive comparative evaluation and combination of automatic rhythm description systems. We evaluate 32 tempo estimation and 16 beat tracking state-of-the-art systems in order to identify their characteristics and investigate how they can be combined to improve performance. Finally, we propose and evaluate the use of voice suppression algorithms for music signals with predominant vocals in order to improve the performance of existing beat tracking methods.

Agustin Martorell defends his PhD thesis

Agustín Martorell defends his PhD thesis entitled "Modelling tonal context dynamics by temporal multi-scale analysis" on Thursday 19th of September 2013 at 10:00h in room 55.410.

The jury members of the defense are: Petri Toiviainen (University of Jyväskylä), Geoffroy Peeters (IRCAM), Sergi Jordà (UPF).

Abstract: This work explores the multidimensional, ambiguous and temporal characteristics of tonality from a holistic perspective. The approach relies on interfacing pitch-spaces with time vs. time-scale descriptions. In this combined representation, the spatial and temporal hierarchies of tonality are evidenced simultaneously and in relation to each other. A visual exploration method is proposed for the analysis of tonal context in music works, using a simple model of tonal induction. A geometrical colouring solution, based on the topology of the pitch-space, approaches the perceptual correlation between the tonal properties and the visual representation. A relational taxonomy is proposed for describing tonal ambiguity, which leads to extending the method for the analysis of music based on tonal systems beyond the major-minor paradigm. Two perceptual studies are approached from this descriptive framework. The first study evidences the impact of time-scale in a simple model of tonal induction, and analyses the mathematical artefacts introduced by evaluations in scaled spaces. In the second study, a model of contextual instability is proposed and discussed in relation to the modelling of tonal tension. The analysis and representation methods are then generalised, through a set-class theoretical domain, in order to be applied with any pitch-based music.
