Music, Embodied Mind, and Cultural Practice: how the self and the other shape musical experience
In this talk, human musicality is inquired in the context of the cultural practice of music. Informed by the theory of social embodied cognition, some musical practices are investigated with the aim of accounting for an ontology of the self and the other in the cultural practice of music. Since the very beginning of life, making sense of music requires human action-perception involvement with the complexity of sonic-kinetic events. This capacity is based on human disposition to build social meaning throughout the interaction of our mind-body-environmental complexes with others’. Musical development is bound to the ways in which the temporal, spatial and dynamic configurations of sound and movement are organized in our self-other interaction, and developed in our imaginative, embodied and emotional cognition. The meaning of the embodied mind and the ways the self and the other in interaction shape human experience in the cultural practice of music are important to discuss an epistemological turn in the fields of musicology, music psychology and music pedagogy, and also to open new music research avenues.

The First Brazilian Symposium on Computer Music presents Brazilian computer music potentials - Caxambu, MG, 1994
The main objective of this talk is to report on the First Brazilian Symposium on Computer Music, which occurred on August 1994, at the city of Caxambu, Minas Gerais, promoted by the UFMG. NUCOM, the group of young academic dedicated to this emerging research field in Brazil, was created as a discussion list by e-mail, during the year of 1993. This quite exciting and fancy event at Hotel Gloria in Caxambu was able to imposingly launch the group to the national, as well as to the international academic community. First, due to the excellency of the event’s output and its daring program, that included 34 selected papers by researchers from various institutions from Argentina, Brazil, Canada, Denmark, France, Hong Kong, Mexico, UK, and USA, 5 lectures an 2 panels of discussion offered by researchers from the most important computer music research centers all over the world. The program also included eight concerts, two of them featuring traditional music, such as Bach, Mozart, and Brazilian music. Six computer music concerts presented 48 selected compositions submitted to the symposium. Second, as the symposium happened as apart of the 14th Congress of Brazilian Computer Science Society (SBC), the excellency of its output was able to attract the interest of SBC’s board of directors. They invited NUCOM to integrate the society as Special Committee, which are sub-groups of SBC dedicated to specific computer science topics. At the end of the description, this report aims at raising questions, arguments, and debates about today’s format of NUCOM meetings, considering more seriously the interdisciplinary character of the methodologic approaches adopted by the field. Interdisciplinarity should be persued by striving to contaminate a growing number of different topics of musical sciences, as well as of other research fields.

The Politics of Computer Music
When a set of objects, actions, and procedures begin to coalesce and gain some coherence, they become perceived as a new, cohesive field. This may be related to the emergence of a new discipline, a new craft, or a new technological configuration. As this new field shows some coherence and unity, we tend to overlook the conditions that gave rise to it. These conditions become “naturalized” as if they were inherent in that field. From this point on, we do not wonder anymore to what extent the contingencies (formal, social, economic, technological, aesthetic, religious) that gave rise to that field have been crucial to its constitution.
When it comes to computer music we are used to its applied perspective: tools, logical models, and algorithms are created to solve problems without questioning the (non-computational) origin of these problems or the directions taken by the solutions we give to them. The idea of computing as a set of abstract machines often hides the various aspects of the sonic cultures that are at play when we develop tools and models in computer music.
The way we connect the development of computer tools with the contingencies and contexts in which these tools are used is what I call the politics of computer music. This connection is often overshadowed in the development of computer music. However, I would like to argue that this connection is behind everything we do in terms of computer music to the point that it often guides the research, development, and results within the field. In this presentation, I would like to consider the politics of computer music as a way to critically explore the field. I’ll also point to some initiatives in this direction that we have developed at the NuSom, the Research Center on Sonology of the University of São Paulo.

Computational Methods for Percussion Music Analysis
Most of the research conducted on information technologies applied to music has been oriented towards mainstream popular music in the so-called ‘Western’ tradition. Although it proved to be effective for various music styles and repertoires, new approaches are needed to deal with other music traditions, such as those from Africa, China, India, or the Arab world. Fortunately, over the last few years there have been increasing efforts devoted to the study of traditional, folk or ethnic music. The computational analysis of rhythm from audio signals remains a challenging task in several cases, for instance, for syncopated or poly-rhythmic music.
This talk offers an overview of the research we conducted over the last few years on computational rhythm analysis from audio recordings, considering the Afro-Uruguayan candombe drumming as a case study. It comprises the creation of datasets, the discovery and analysis of rhythmic patterns, the study of micro-timing and the development of algorithms for beat and downbeat tracking. Besides, it also discusses our current efforts to improve and extend the methods to other music traditions, in particular, to Afro-Brazilian Samba.
All the concerts will be at CCUFSJ - Solar da Baronesa.
