A improvisação como ferramenta pedagógica no ensino vocacional de piano

Resumo I - A frequência do Estágio do Ensino Especializado proporcionou uma oportunidade de observar o ensino de piano numa das escolas mais importantes do ensino da música em Portugal, acompanhando alunos do Curso Básico e do Curso Secundário, que frequentaram a Escola de Música do Conservatório Nacional no regime integrado. O processo de observação de aulas que decorreu deste estágio possibilitou-nos assistir às aulas de piano de uma professora experiente, permitindo a observação de metodologias consolidadas e assistir de perto à forma como estas são postas em prática. Por outro lado, através da leccionação de aulas observadas, foi dada a oportunidade de testar e reflectir sobre o próprio desempenho docente, procurando estratégias e ferramentas pedagógicas que possam vir a acrescentar qualidade à prática pedagógica. O ensino especializado da música em Portugal tem experimentado mudanças importantes, o que leva a que haja uma adaptação das escolas às mudanças, continuando a leccionar um ensino de qualidade, que se quer cada vez mais eficaz, inovador, e com professores cada vez melhor fundamentados e preparados.

Love, politics, time

Featuring the musical compositional techniques of phase, repetition and pulse, with the sounds of New York recorded from a 16th floor hotel window, this sonic poem is a plea for the intimately spoken word. As cockatoos rise in the white siren sky, two lovers confront love and time in a halting conversation inside a placeless shelter.
This performance work is a poetic and musical experimentation with ideas from the philosopher Alain Badiou. The intersection of political and amorous truth procedures thought to form the subject matter of many novels is extended upon by presenting such an intersection via the crossing of genres of music, sound art, poetry, prose and theatre. This collaborative venture forms a continuing experiment with the idea that music does not simply form a corollary with words and their representation in sound, but rather explores ways in which music can form an antagonistic relationship to the spoken word.
'Conversation in an air raid shelter' was originally presented as a live performance at Double Dialogues Conference: 'The 21st century - The Event, The Subject, The Artwork', Fiji, 2012 and the audio recording appears in Double Dialogues Issue 16, Spring 2013 with an accompanying discursive article 'Love, Politics, Time'. It is available on CD and Youtube. It was also performed at the Torquay Literary Festival in 2013. A discussion of its process by Josephine Scicluna features on a video currently in production by Deakin University for a new unit on creativity in the Bachelor of Arts program.

Música e surdez: o ensino de música numa perspectiva bilíngue na escola regular

The present study focuses on the development of pedagogical activities in Music Teaching, aiming to enhance the accessibility of musical knowledge for both deaf and hearing students, using a bilingual approach in regular schools. Few studies address Music and Deafness, and those that do focus exclusively on the context of special education, and specifically the deaf student, which signals the urgent need for conducting research on this issue in the context of inclusion – empirically and carried out on school grounds. Therefore, we developed our study at a Natal City Public Elementary school, in a class of 6th graders, comprised of 37 students, 3 of whom were deaf. The objective of the study was to develop a proposal for a pedagogical intervention in Music Teaching, using a bilingual approach, with deaf and hearing students, in the context of regular school classes. The research is based on the theoretical framework presented in Penna (2010), Brito (2001) and Fonterrada (2008), with reference to music education, and Haguiara-Cervellini (2003), Finck (2009) and Louro (2006), with reference to inclusion in teaching music. To achieve this objective, we developed a proposal for intervention based on the methodological dictates of intervention research, presented in studies by Jobim and Souza (2011) in light of the theoretical concepts posited by Mikhail Bakhtin, which assert that knowledge is produced through interaction between subjects, dialogically and through alterity. This methodology was carried out in pedagogical workshops, conceived as spaces for the construction of knowledge, mobilizing participants to engage in ludic activities of musical experimentation. Content covered in these workshops focused on Pulse and Rhythm – basic elements in music education – demonstrating that awareness about and sensitivity to these elements is not limited to the auditory sensory perception of the student, once the entire body is used as an agent of acquisition and expression. Thus, we began the trajectory of our research from the starting point of the identification and perception of „Pulse‟, using one‟s own body and the body of classmates, representing it through physical expressions and movement. Subsequently, this Pulse was extended from the body to a percussion instrument, and was then represented graphically as lines of rhythm, constituting a process of reading and writing; ultimately the intervention culminated in the class presentation with the musical group De Pau e Lata (Stick and Can). In our analysis, faced with the challenges and possibilities presented in our study, findings showed satisfactory results with regard to the participation of all of the students: completing the activities proposed in the class, asking questions when they did not understand, positioning themselves when they thought it necessary, expressing opinions about the work completed, evaluating the workshops given, interacting, helping in the activities, constructing knowledge collaterally, experimenting and experiencing musical elements through the body in activities that applied to both groups (deaf and hearing) in the one class. These indications elucidate the viability of teaching music to deaf and hearing students, using a bilingual approach, and based on experiences with the body and communicative and cultural specificities involved, confirming, as well, the role of Sign Language as a mediator in the teaching/learning process.

New trends in musical genre classification using optimum-path forest

Musical genre classification has been paramount in the last years, mainly in large multimedia datasets, in which new songs and genres can be added at every moment by anyone. In this context, we have seen the growing of musical recommendation systems, which can improve the benefits for several applications, such as social networks and collective musical libraries. In this work, we have introduced a recent machine learning technique named Optimum-Path Forest (OPF) for musical genre classification, which has been demonstrated to be similar to the state-of-the-art pattern recognition techniques, but much faster for some applications. Experiments in two public datasets were conducted against Support Vector Machines and a Bayesian classifier to show the validity of our work. In addition, we have executed an experiment using very recent hybrid feature selection techniques based on OPF to speed up feature extraction process. © 2011 International Society for Music Information Retrieval.

Expressão musical na educação pré-escolar: constrangimentos e práticas educativas

Com o intuito de conhecer e combater os principais constrangimentos que levam os(as) educadores(as) de infância a não implementar atividades de expressão musical, ou à sua escassa implementação, este relatório intitulado “Expressão Musical na Educação Pré-escolar - Constrangimentos e Práticas Educativas” pretende apresentar algumas atividades, neste domínio, que poderão ser desenvolvidas por educadores(as) cuja formação inicial é globalizante e não específica - contribuindo, deste modo, para a prática educacional em contexto pré-escolar. O presente relatório enquadra-se no âmbito do Mestrado em Educação Pré-escolar, mais concretamente na unidade curricular de Prática e Ensino Supervisionada, e apresenta ainda a descrição e reflexão do percurso realizado numa instituição pública de educação pré-escolar. Para o desenvolvimento deste trabalho, como profissionais reflexivos, recorreu-se à metodologia de Investigação-Ação. Neste sentido desenvolveu-se uma atitude de pesquisa, experimentação, análise e reflexão, sendo estas as ações elementares para melhorar a prática educativa e dar às crianças uma educação de qualidade.

Elaboração de material pré-composicional através de expansão de procedimentos do sistema Schillinger de composição musical

The work aims at investigating possibilities of extending compositional procedures, based on the Schillinger System of Musical Composition (SSMC). I start by elaborating a brief historical review on SSMC, which is followed by a critical review of the System. The work includes a state of the art on the research on this topic, performed upon analysis of the current work conducted by a research group from the UFRN Music School from which I also make part. The main line of the research is to elaborate on the suggestion of extending the SSMC concept of place of attack to the idea of place of instrumentation, through developing a binary instrumentation procedure. The experimentation on the thesis‟ hypothesis is presented in my composition titled “Suíte Grega” (Greek Suite), a compositional memoir for Oboe, Saxophone and 3 Cellos.

Generation in context : an exploratory method for musical enquiry

This paper discusses a method, Generation in Context, for interrogating theories of music analysis and music perception. Given an analytic theory, the method consists of creating a generative process that implements the theory in reverse. Instead of using the theory to create analyses from scores, the theory is used to generate scores from analyses. Subjective evaluation of the quality of the musical output provides a mechanism for testing the theory in a contextually robust fashion. The method is exploratory, meaning that in addition to testing extant theories it provides a general mechanism for generating new theoretical insights. We outline our initial explorations in the use of generative processes for music research, and we discuss how generative processes provide evidence as to the veracity of theories about how music is experienced, with insights into how these theories may be improved and, concurrently, provide new techniques for music creation. We conclude that Generation in Context will help reveal new perspectives on our understanding of music.

Eco-structure data forms : classification of data analysis using perceived design affordances for musical outcomes

This paper explores a method of comparative analysis and classification of data through perceived design affordances. Included is discussion about the musical potential of data forms that are derived through eco-structural analysis of musical features inherent in audio recordings of natural sounds. A system of classification of these forms is proposed based on their structural contours. The classifications include four primitive types; steady, iterative, unstable and impulse. The classification extends previous taxonomies used to describe the gestural morphology of sound. The methods presented are used to provide compositional support for eco-structuralism.

Changing musical emotion : a computational rule system for modifying score and performance

When communicating emotion in music, composers and performers encode their expressive intentions through the control of basic musical features such as: pitch, loudness, timbre, mode, and articulation. The extent to which emotion can be controlled through the systematic manipulation of these features has not been fully examined. In this paper we present CMERS, a Computational Music Emotion Rule System for the control of perceived musical emotion that modifies features at the levels of score and performance in real-time. CMERS performance was evaluated in two rounds of perceptual testing. In experiment I, 20 participants continuously rated the perceived emotion of 15 music samples generated by CMERS. Three music works, each with five emotional variations were used (normal, happy, sad, angry, and tender). The intended emotion by CMERS was correctly identified 78% of the time, with significant shifts in valence and arousal also recorded, regardless of the works’ original emotion.

View from a bridge : what makes a musical city

The attention paid by the British music press in 1976 to the release of The Saints first single “I’m Stranded” was the trigger for a commercial and academic interest in the Brisbane music scene which still has significant energy. In 2007, Brisbane was identifed by Billboard Magazine as a “hot spot” of independent music. A place to watch. Someone turned a torch on this town, had a quick look, moved on. But this town has always had music in it. Some of it made by me. So, I’m taking this connection of mine, and working it into a contextual historical analysis of the creative lives of Brisbane musicians. I will be interviewing a number of Brisbane musicians. These interviews have begun, and will continue to be be conducted in 2011/2012. I will ask questions and pursue memories that will encompass family, teenage years, siblings, the suburbs, the city, venues, television and radio; but then widen to welcome the river, the hills and mountains, foes and friends, beliefs and death. The wider research will be a contextual historical analysis of the creative lives of Brisbane musicians. It will explore the changing nature of their work practices over time and will consider the notion, among other factors, of ‘place’ in both their creative practice and their creative output. It will also examine how the presence of the practitioners and their work is seen to contribute to the cultural life of the city and the creative lives of its citizens into the future. This paper offers an analysis of this last notion: how does this city see its music-makers? In addition to the interviews, over 300 Brisbane musicians were surveyed in September 2009 as part of a QUT-initiated recorded music event (BIGJAM). Their responses will inform the production of this paper.

Defibrillator

Defibrillator is a 16’41” musical work for solo performer, laptop computer and electric guitar. The electric guitar is processed in real-time by digital signal processing network in software, with gestural control provided by a foot-operated pedal board. --------- The work is informed by a range of ideas from the genres of electroacoustic music, western art music, popular music and cinematic sound. It seeks to fluidly cross and hybridise musical practices from these diverse sonic traditions and to develop a compositional language that draws upon multiple genres, but at the same time resists the ability to be located within a singular genre. Musical structures and sonic markers which form genre are ruptured at strategic levels of the musical structure in order to allow for a cross flow of concepts between genres. The process of rupture is facilitated by the practical implementation of music and sound reception theories into the compositional process. -------- The piece exhibits the by-products of a composer born into a media saturated environment, drawing on a range of musical and sonic traditions, actively seeking to explore the liminal space in between these traditions. The project stems from the author's research interests in locating points of connection between traditions of experimentation in diverse musical and sonic traditions arising from the broad uptake of media technologies in the early 20th century.
