Seminar by George Tzanetakis on Physical Modelling
24 Oct 2013

George Tzanetakis, from University of Victoria (Canada), gives a talk on "Physical Modelling Beyond Sound Synthesis: three case studies" on Thursday October 24th at 15:30h in room 52.321.

Abstract: Physical modelling synthesis refers to a set of sound synthesis techniques in which the generated sound is computed as the output of a set of equations describing the actual physics of sound production of musical instruments. It can be viewed as a virtual simulation of the physical world. Physical modelling synthesis has many advantages including rich realistic sound, meaningful control parameters (such as the length of a string), and computational efficiency. One of the main challenges is that, similarly to actual acoustic music instruments, the control of physical models is not trivial as there are many regions of the parameter space that produce undesirable output sound. In this talk I will describe three case studies of combining concepts from different research areas (namely New Interfaces for Musical Expression and Music Information Retrieval) and physical modelling synthesis that attempt to address this control issue:

  1.  the SoundPlane which is a multi-touch pressure sensitive surface  that provides rich control possibilities
  2. the hybrid Gyil (an African Xylophone from Ghana) in which the buzzing gourds are physically modeled on a computer but the actual wooden bars are retained and
  3. Vivi, a virtual violinist that is taught how to bow a physical violin model similarly to how a beginner player learns to bow an actual acoustic violin.

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.
