A expressividade é um elemento chave para o transporte de emoções em música, e seu modelamento, vital para a concepção de sistemas de síntese mais realistas. Gestos musicais executados durante a interpretação usualmente portam a informação responsável pela expressividade percebida, e podem ser rastreados por meio de padrões sônicos a eles associados em diversas escalas de resolução. Um conjunto relevante de gestos musicais expressivos foi estudado através de uma análise em multiresolução utilizando-se a transformada wavelet. A escolha deve-se principalmente à capacidade natural desta ferramenta em realizar análises de tempo-escala/frequência, e suas semelhanças com o processamento dos estágios primários do sistema auditivo. Vinte e sete eventos musicais foram capturados em interpretações de violino e flauta, e analisados com o objetivo de avaliar a aplicabilidade desta ferramenta na identificação e segregação de padrões sônicos associados a gestos musicais expressivos. Os algoritmos wavelet foram implementados na plataforma MATLAB utilizando-se bancos de filtros organizados em esquema piramidal. Rotinas para análises gráfica e sônica e uma interface ao usuário foram também implementadas. Verificou-se que as wavelets permitem a identificação de padrões sônicos associados a gestos expressivos exibindo diferentes propriedades em níveis diferentes da análise. A técnica mostrou-se útil para isolar ruídos oriundos de fontes diversas, extrair transientes associados a gestos súbitos e/ou intensos, e para segregar a estrutura harmônica de tons musicais, entre outras potencialidades não menos importantes. Particularidades da técnica e efeitos secundários observados são discutidos, e os padrões sônicos observados nos níveis wavelets são correlacionados com os gestos musicais que lhes deram origem. São propostos trabalhos futuros objetivando a investigação de certos eventos musicais e fenômenos verificados, bem como o estudo de implementações alternativas. / Expressiveness is a key element for emotion transportation in music, and its modeling necessary to conceive more realistic synthesis systems. Musical gestures executed during a performance carry the information answering for expressiveness, and may be tracked by means of sonic patterns associated to them within several resolution scales. A relevant set of musical gestures was studied through a multiresolution analysis using the wavelet transform. The choice for this tool is mainly due to its natural ability to perform time-scale/frequency analysis, and for its similarities with early auditory processing stages. Twenty seven musical events were captured from violin and flute performances, and analyzed in order to evaluate the applicability of this tool for identification and segregation of sonic patterns associated with expressive musical gestures. The wavelet algorithms were implemented on the MATLAB platform, employing filter banks organized in a pyramidal scheme. Graphical and sonic analysis routines and a user interface were carried out over the same platform. It was verified that wavelets enable the identification of sonic patterns associated to musical gestures revealing different properties on different levels of the analysis. The technique showed up useful to isolate noise from different sources, extract transients associated to sudden and/or intense gestures, and segregate the tonal harmonic structure, among other important features. Particularities of the technique and secondary effects observed are discussed, and sonic patterns on wavelet levels are correlated with the musical gestures which produced them. Future works are proposed addressing further investigation of certain musical events and phenomena observed, as well as the study of alternative implementations.

Composing or arranging for orchestra is a skill which is hard to learn and hard to teach. Literature on orchestration is comprehensive in terms of rules of thumb and these heuristic tools are sometimes called principles of orchestration. However, a study of the literature on orchestration revealed that these 'principles' are not theories about the outcomes and effects of specific decisions made by composers. An exception is the work of George McKay who does indeed establish principles of orchestration to some extent. Granting a few exceptions, literature on orchestration takes as point of departure recommendations about techniques of orchestration and illustrates these techniques with analyses of existing compositions for orchestra. In this study I invert the approach followed in the literature and take music analysis as a point of departure for my study. I used an existing and conventional analysis of Claude Debussy's Syrinx for solo flute from the book Sonic Design: The Nature of Sound and Music by Robert Cogan and Pozzi Escot (1976) as context for my own analysis of Syrinx in which the less familiar type of analysis – the analysis of musical gestures and musical forces – can be understood. This analysis formed the basis for my orchestral composition titled Ananke which is based upon musical gestures from Syrinx. A reinterpretation of Cogan and Escot's analysis of Debussy's Syrinx enabled me to identify the musical gestures I used as a basis for my orchestral composition. Musical gestures are understood in this dissertation in terms of the theory of musical forces by Steve Larson. The objective in composing Ananke, based upon material from Syrinx by Debussy, is to explore different ways in which the musical gestures can be orchestrated in order to amplify the three musical forces namely musical gravity, musical magnetism and musical inertia. This process of composing the orchestral composition enabled me to construe principles of orchestration concerning musical forces and the different ways in which musical forces can be amplified. I found that the approach I followed in this study can indeed be employed in order to investigate and construe principles of orchestration, taking music analysis as a point of departure. This new approach to the study of orchestration opens up new possibilities in teaching and learning orchestration, as well as in composing or arranging for orchestra. / Thesis (MMus (Composition))--North-West University, Potchefstroom Campus, 2013.

Este trabalho apresenta um estudo analítico dos elementos melódicos e gestuais presentes em Notas Soltas (1978) para flauta transversal solo e Notas Irresponsáveis (1986/87) para trio de flautas transversais de Bruno Kiefer. O livro Introduction to Post-Tonal Theory de Joseph Straus é utilizado como referencial teórico para a abordagem melódica. Buscamos identificar quais são os padrões de escrita empregados pelo compositor e procurar relações entre as duas peças. Utilizamos o catálogo de Gestos Musicais apresentados por Luciane Cardassi em A música de Bruno Kiefer : "terra", "vento", "horizonte" e a poesia de Carlos Nejar. Através dos resultados dessas análises, procuramos entender como se dá a escrita idiomática do compositor, bem como encontrar traços em comum entre repertório escolhido para essa pesquisa e obras de Kiefer investigadas por outros autores. / The purpose of this work is to present an analytical study of the melodic elements and gestures in Bruno Kiefer’s pieces entitled Notas Soltas (1978) for solo flute and Notas Irresponsáveis (1986/87) for flute trio. The theoretical framework for the melodic approach is based on Joseph Straus’ Introduction to Post-Tonal Theory. The aim has been to identify the musical patterns employed by the composer and their relationship in both works. The catalogue of Musical Gestures compiled by Luciane Cardassi in A música de Bruno Kiefer: "terra", "vento", "horizonte" e a poesia de Carlos Nejar was also used. Through the analyses of these two works it was possible to understand the idiomatic character of Kiefer’s style, while finding common traces in other works by the same composer.

Engaging in the music set of one’s favorite artist or DJ is oftentimes leading to the result of a powerful and euphoric felt experience, a sensation partly also induced from dancing in beat to the music. In an attempt to simulate a similar dance experience, this user-study examines when a user is let to dance in rhythm to a music playback and in addition, in control of a music playback tempo through the generated dance movements. A proof-of-concept prototype was built and tested in an initial study, followed by a main study where the prototype had been modified and 12 participants participated. A questionnaire was given containing various question statements to be rated through a Likert-scale regarding their subjective experience. Open-ended questions were also included to collect their own opinions. From the results, an enhanced engagement and enjoyment of the music could be identified when being able to manipulate the tempo. / Att engagera sig i ett musik-set av ens favoritartist eller DJ leder ofta till resultatet av en kraftfull och euforisk känsloupplevelse, en känsla delvis framkallat av att man dansar i takt med musiken. I ett försök att simulera en liknande dansupplevelse undersöker denna användarstudie när en användare dansar i rytm till musik och dessutom är i kontroll av tempot genom de skapade dansrörelserna. En proof-of-concept prototyp konstruerades och testades i en första studie, följt av en huvudstudie där prototypen hade modifierats och 12 deltagare deltog. Ett frågeformulär gavs med olika frågor som skulle bedömas via en Likert-skala, med avseende på deras subjektiva erfarenhet. Öppna frågor ingick också för att samla deras egna åsikter. Från resultaten kunde ett ökat engagemang och en förhöjd njutning av musiken identifieras när man kunde manipulera tempot.

Syftet med denna studie var att undersöka hur musikhögskolestuderande med trummor som huvudinstrument uppfattar hur melodisk koordination påverkar deras lärande. Övningarna är specifikt konstruerade för trumset för att fungera som ett verktyg till att öppna upp den musikaliska lyhördheten och periodkänslan samt vara en effektiv övning för koordination och balans. I denna studie deltog fem informanter under utbildning på Kungl. Musikhögskolan i Stockholm. Metoden som användes var att genom loggböcker från informanterna analysera deras beskrivningar av min frågeställning. För att få fram underlag för analys av undersökningen har informanterna fått fem frågor att besvaras under den 10 veckors period då de arbetade med övningarna. I resultatet beskrev informanterna hur de uppfattade sin progression och hur de verkade förändra sin medvetenhet om denna mellan tillfällena. Resultaten visar att informanterna upplevde att deras rytmiska gehör samt musikaliska periodkänsla förbättrats. De erfor även att övningarna förstärkte deras timing och inspirerade till nytt melodiskt synsätt. I kapitlet diskussion ligger betoningen på den ifrågasättande aspekten: Vad är resultatet av denna studie och har forskningsfrågorna besvarats. / The purpose of this study was to investigate how music students, playing the drums, interpret melodic coordination in aspects of learning. In this study five students from the Royal Academy of Music in Stockholm participated. The students were given exercises, specifically designed for drums. These exercises are to be used as keys to unlock and further develop the musical awareness and the awareness of musical periods. Furthermore are these exercises an efficient way to train the coordination and balance. To be able to get material for the analysis of this study, journals have been used. These journals were given to the students who during a 10-week period of time used the exercises and answered the five theses. In the result the students described their progression and their awareness of progression during the ten weeks. The results show that the students experienced an improvement of their rhytmical pitch and their periodicity in musical performance . Further state that the exercises improved their timing and inspired a new melodic point of view. Finally I discuss the purpose of this study, the result and whether or not the theses have been answered.
