Phonos/MTG Exhibit at the Museu de la Música in Barcelona

To celebrate 40 years of Phonos (20 of which are also part of the history of the MTG) we have organized an Exhibit at the Museu de la Música in Barcelona. Through the presentation of 10 electronic instruments that were either developed or used at Phonos/MTG we review our history in the field of electronic music, going over some of the people that made this history and presenting some of the music that resulted from it.

Phonos was created in 1974 by Andrés Lewin-Richter, Josep Maria Mestres Quadreny and Lluís Callejo as an electronic music laboratory and in 1994 Phonos became part of the Universitat Pompeu Fabra, resulting in the creation of Music Technology Group (MTG). Very interesting things have happened in these 40 years and relevant contributions have been made to the world of Electronic Music. To learn a bit about this you will have to go to the Museu de la Música in Barcelona. 

The Exhibition opens on December 18th 2014 and will remain open until September 27th 2015.

Marco Marchini defends his PhD thesis on November 27th
27 Nov 2014

Marco Marchini defends his PhD thesis entitled "Analysis of Ensemble Expressive Performance in String Quartets: a Statistical and Machine Learning Approach" on Thursday November 27th 2014 at 12:00h in room 55.309 of the Communication Campus of the UPF.

The jury of the defense is: Xavier Serra (UPF), Josep Lluís Arcos (IIIA-CSIC), Roberto Bresin (KTH).

Abstract: Computational approaches for modeling expressive music performance have produced systems that emulate human expression, but few steps have been taken in the domain of ensemble performance. Polyphonic expression and inter-dependence among voices are intrinsic features of ensemble performance and need to be incorporated at the very core of the models. For this reason, we proposed a novel methodology for building computational models of ensemble expressive performance by introducing inter-voice contextual attributes (extracted from ensemble scores) and building separate models of each individual performer in the ensemble. We focused our study on string quartets and recorded a corpus of performances both in ensemble and solo conditions employing multi-track recording and bowing motion acquisition techniques. From the acquired data we extracted bowed-instrumentspecic expression parameters performed by each musician. As a preliminary step, we investigated over the dierence between solo and ensemble from a statistical point of view and show that the introduced inter-voice contextual attributes and extracted expression are statistically sound. In a further step, we build models of expression by training machine-learning algorithms on the collected data. As a result, the introduced inter-voice contextual attributes improved the prediction of the expression parameters.
Furthermore, results on attribute selection show that the models trained on ensemble recordings took more advantage of inter-voice contextual attributes than those trained on solo recordings. The obtained results show that the introduced methodology can have applications in the analysis of collaboration among musicians.

We are launching the AcousticBrainz project today!

The AcousticBrainz project aims to crowd source acoustic information for all music in the world and to make it available to the public. This acoustic information describes the acoustic characteristics of music and includes low-level spectral information and additional high level descriptors for genres, moods, keys, scales and much more. The goal of AcousticBrainz is to provide music technology researchers and open source hackers a massive database of information about music. We hope that this database will spur the development of new music technology research and allow music hackers to create new and interesting recommendation and music discovery engines.

AcousticBrainz is a joint effort between the MusicBrainz project and our research group, being originally envisioned by Xavier Serra. At the heart of this project lies the Essentia software library, our open source toolkit that allows the automatic analysis of music. The output from Essentia is collected by the AcousticBrainz project and made available to the public under CC0 license (public domain). In 6 weeks since its inception, AcousticBrainz contributors have already submitted data for 650,000 audio tracks using the pre-release software. Today, AcousticBrainz also releases a music analysis tool for Mac, Linux and Windows to the general public, which will allow many more people to contribute data from their personal music collections.

This new project is being presented today by Robert Kaye, founder of MusicBrainz and Executive Director of the MetaBrainz Foundation, at the Music 4.5 Open Data in which a session is devoted to discuss the value of music content and music related data and how open data could be a catalyst for monetising music content. AcousticBrainz will also be presented at Strata Conference tomorrow in a session titled 'Disrupting the Music Tech Space with Open Data'.

Tutorial on Beijing Opera and computational tools for its analysis
18 Nov 2014 - 20 Nov 2014

This is a 3 hours tutorial that we gave at ISMIR in Taipei and that now we are doing it again here:

Jingju music: concepts and computational tools for its analysis
Xavier Serra, Rafael Caro Repetto, Sankalp Gulati, Ajay Srinivasamurthy
Tuesday, Nov 18, & Thursday, Nov 20, 10:00am-12:00pm, Room 55.230

Abstract: Jingju (also known as Peking or Beijing opera) is one of the most representative genres of Chinese traditional music. From an MIR perspective, jingju music offers interesting research topics that challenge current MIR tools. The singing/acting characters in jingju are classified into predefined role-type categories with characteristic singing styles. Their singing is accompanied by a small instrumental ensemble, within which a high pitched fiddle, the jinghu, is the most prominent instrument within the characteristic heterophonic texture. The melodic conventions that form jingju modal systems, known as shengqiang, and the percussion patterns that signal important structural points in the performance offer interesting research questions. Also the overall rhythmic organization into pre-defined metrical patterns known as banshi makes tempo tracking and rhythmic analysis a challenging problem. Being Chinese a tonal language, the intelligibility of the text would require the expression of tonal categories in the melody, what offers an appealing scenario for the research of lyrics-melody relationship. The role of the performer as a core agent of the music creativity gives jingju music a notable space for improvisation. The lyrics and scores cannot be taken as authoritative sources, but as transcriptions of particular performances.

In this tutorial we will give an overview of Jingju music, of the relevant problems that can be studied from an MIR perspective and of the use of specific computational tools for its analysis. The tutorial will be organized in three parts. The first will be an introduction to Jingju from a musicological perspective, the second will cover diverse audio analysis tools of relevance to the study of Jingju (using http://essentia.upf.edu), and finally in the last part we will present and discuss specific examples of analyzing Jingju arias using those tools (work done in the context of http://compmusic.upf.edu).
