Cordialmente Jos´eEduardo Fornari Novo Jr. Coordenador geral do SBCM 2015 Introduction The SBCM Brazilian Symposium on Computer Music is a biannual event with international recognition in the field of computer music organized by NUCOM, the computer music interest group of the Brazilian Computer Society (SBC). This 15th edition will be held from November 23th to 25th, 2015, at Campinas, S˜ao Paulo, and is specially dedicated to the theme ”Computer Music: beyond the frontiers of signal processing and computational models”. From electroacoustic experiments to the most complex sound generation and human machine interfaces, signal processing and computational models always had an important role. The proposed theme for this SBCM brings up discussions about aspects that are also inherent to the computer music field, as math, creativity, aesthetic meaning, virtual reality and social networks. Welcome It is always a pleasure to organize an event with the status of SBCM; the Brazilian Symposium on Computer Music. This is undoubtedly one of the most important national events in the field of music and technology, with decades of academic tradition and the active presence of important names of this field of study, that intersects Science, Techno- logy and Art. The local organization started its activities in the first half of 2015, when it was formally decided that the SBCM 2015 would indeed be held at the University of Campinas, UNICAMP. I, the local organizer, researcher at NICS (the Interdisciplinary Center for Sound Communication), and former participant of previous SBCM events, felt comfortable and aligned with the purposes and interests of this event. I must say that the organization process happened in a rather peaceful, productive and motivating way. In order to have that happened, the local organization had the privilege of counting with the support of various departments at UNICAMP, especially with the staffs of: Convention Center (CDC), the Department of Music, at the Institute of Arts, and NICS. In terms of people, I thank the invaluable cooperation of Elizabeth Fernandes (Beth, from NICS), who actively participated in each and every detail of SBCM 2015 organization; Prof. Dra. Adriana Mendes (NICS coordinator and also member of the local organizing team), as well as all other members of this staff, namely: Ana Lia, Gerson Abdala, Gisele Gomes, Francieli Moreira, Angelica Pe˜na, Miguel Clementi, Djalma de Campos, Sandra Cielavin, Rafael de Almeida, Tiago Tavares, Charles Santana, Gabriel Rimodi. Alexandre Henrique and Matteo Ricciard. As usual, this SBCM also had the promotion of the Brazilian Computer Society, SBC, which I here acknowledge. We also had the privilege of having the financial support of CAPES, the Brazilian Coordination for Higher Education and Personnel Improvement, which once again supported an SBCM event, as well as FAEPEX, the Fund for Support Education, at PRP / UNICAMP. Finally, I also thank CECM, the Special Committee on Computer Music, in the person of Prof. Dr. Leandro Costa- longa, as well as SBCM 2015 technical section coordinator, Prof. Dr. Flavio Schiavoni; and musical coordinator, Prof. Dr. Rodrigo Schramm. I hope that this SBCM 2015 turns to be an event that succeeds to bring about invaluable contributions for the research, dissemination and development of computer music field that still stands as one of the large aggregating fronts for the analysis, processing, composition and performance in contemporary music. Best regards, Jos´eEduardo Fornari New Jr. General Chair of the SBCM 2015 Carta da CECM/SBC Na sua 15° edi¸c˜ao, o Simp´osio Brasileiro de Computa¸c˜ao (SBCM), se volta para al´em das fronteiras dos processamento de sinais e modelos computacionais.

  • Some Lisp Tools for Musicology Research Aids for an Electronic Corpus of Lute Music
    Some Lisp tools for musicology Research aids for an Electronic Corpus of Lute Music David Lewis,∗ Christophe Rhodes† Centre for Cognition, Computation and Culture Goldsmiths College, University of London New Cross, London, SE14 6NW 28th June 2006 Abstract We present the tools that have been developed in the course of implementing a resource to assist in musicological investigation of lute music. We discuss the use we have made of current Lisp-based technologies in our applications, and the modifications and customizations we have needed to make. Our tools both have the current ability to service musicological queries, and have an evident path for further development to enhance their utility. 1 Introduction There is a long history of association between musicology and computer technology. The term ‘Music Information Retrieval’ dates back at least as far as 1966 [1], and the earliest computer-based music encoding and analysis initiative, centred around the works of Josquin des Prez, was started by Lewis Lockwood and Arthur Mendel in Princeton at 1963 [2]. It is perhaps surprising, therefore, that the impact of computing on the discipline has been negligible. One reason for this is the complexity of some of the tasks required: music analysis is frequently very difficult or even impossible to specify algorith- mically and artistic, interpretative or creative processes pose special challenges. This is not, however, the case for all musicological tasks, and probably the greatest impediment to routine, productive use of computers for musicology lies in a severe lack of encoded data. Lisp’s history predates even the use of computers in musicology; the vibrancy of the user community has ebbed and flowed over the last 45 years, but it is relatively clear that Lisp is emerging from the downturn of the AI Winter: over the last five years, many developments (including implementation maintenance, library development, and the continuation of Moore’s law) have made it easier for users to run powerful software on their desktop computers.

  • A Free Implementation of CLIM
    A Free Implementation of CLIM Robert Strandh∗ Timothy Moorey August 17, 2002 Abstract McCLIM is a free implementation of the Common Lisp Interface Man- gager, or CLIM, specification. In this paper we review the distinguishing features of CLIM, describe the McCLIM implementation, recount some of the history of the McCLIM effort, give a status report, and contemplate future directions. McCLIM is a portable implementation of the Common Lisp Interface Man- gager, or CLIM, specification[9] released under the Lesser GNU Public License (LGPL). CLIM was originally conceived as a library for bringing advanced fea- tures of the Symbolics Genera system[3], such as presentations, context sensitive input, sophisticated command processing, and interactive help, to Common Lisp implementations running on stock hardware. The CLIM 2.0 specification added \look-and-feel" support so that CLIM applications could adopt the appearance and behavior of native applications without source code changes. Several Lisp vendors formed a consortium in the late 80s to share code in a common CLIM implementation, but for a variety of reasons the visibility of CLIM has been limited in the Common Lisp community. The McCLIM project has created an implementation of CLIM that, in the summer of 2002, is almost feature complete. Initially created by merging several developers' individual efforts, McCLIM is being used by several programs including a music editor, a web browser, and an IRC client (see Figure 1). Some non-graphic parts of CLIM have been adopted into the IMHO web server[2]. In this paper we review the distinguishing features of CLIM, describe the McCLIM implementation, recount some of the history of the McCLIM effort, give a stlatus report, and contemplate future directions for McCLIM.

Algorithmic Music Analysis: A Case Study of a Prelude from David Cope’s “From Darkness, Light.” Doctor of Philosophy (Music Theory), May 2015, 433 pp., 16 tables, 57 figures, 125 examples, bibliography, 278 titles. The use of algorithms in compositional practice has been in use for centuries. With the advent of computers, formalized procedures have become an important part of computer music. David Cope is an American composer that has pioneered systems that make use of artificial intelligence programming techniques. In this dissertation one of David Cope’s compositions that was generated with one of his processes is examined in detail. A general timeline of algorithmic compositional practice is outlined from a historical perspective, and realized in the Common Lisp programming language as a musicological tool. David Cope’s compositional output is summarized with an explanation of what types of systems he has utilized in the analyses of other composers’ music, and the composition of his own music. Twentieth century analyses techniques are formalized within Common Lisp as algorithmic analyses tools.
