Detta är en studie som handlar om att förbereda sig inför en trumpetprovspelning till en symfoniorkester och en dokumentation av den processen samt en undersökning huruvida man kan få till ett rikare trumpetspel med erfarenhet och kunskap vad beträffar trumpetteknik, orkestertradition, repertoarkännedom och djupare förståelse kring musiken. Jag kommer att analysera två inspelningar jag gör med trumpetutdrag ur den symfoniska orkesterrepertoaren för att sedan komma fram till en avslutande tredje inspelning. / <p>Tidigare efternamn: Svensson</p>

A degradação de pastagem é um dos maiores problemas da pecuária bovina do país. A implantação seguida de um sistema de manejo inadequado favorece a ocorrência de plantas daninhas em altas densidades, o que diminui a produtividade da gramínea forrageira. A espécie Tecoma stans, importante planta daninha em pastagens, é considerada de difícil controle, pois apresenta rebrota rápida e vigorosa após o corte do tronco, dificultando seu controle por métodos exclusivamente mecânicos. Visando encontrar alternativas de controle químico e conhecer a forma como fatores ambientais influenciam a germinação e emergência da espécie, analisou-se a influência da luz e temperatura sobre a germinação e o efeito da profundidade de semeadura na emergência de T. stans. Além disso, foram estudadas a absorção, a translocação e a eficácia do herbicida aminocyclopyrachlor. Para análise do efeito da luz, sementes foram distribuídas em caixas de plástico transparente e preto, e mantidas em germinador em temperatura constante e alternada. O efeito da temperatura foi avaliado em nove intervalos de temperatura, entre 15°C e 40°C. Para o estudo da influência da profundidade de semeadura na emergência de plântulas, as sementes foram depositadas a 0, 20, 40 e 80 mm de profundidade. A absorção e translocação de 14C-aminocyclopyrachlor foram estudadas ao longo do tempo em plantas jovens de T. stans e os experimentos no campo foram conduzidos com aplicações no toco de aminocyclopyrachlor e picloram e aplicações foliares da associação formulada dos herbicidas aminocyclopyrachlor + metsulfuron-methyl e glyphosate. Os estudos do efeito da luz e temperatura demonstraram que a espécie é fotoblástica neutra e que as temperaturas estudadas não são fatores limitantes para a germinação de espécie, apresentando porcentagem de germinação acima de 50%. A espécie apresentou maior porcentagem de emergência quando as sementes foram depositadas na superfície do solo e não ocorreu emergência das plântulas quando foram depositadas nas profundidades de 40 e 80 mm. Aproximadamente 20% do total de 14Caminocyclopyrachlor aplicado foram absorvidos pelas folhas de T. stans e a porcentagem de translocação não ultrapassou 5% do total aplicado em 72 horas após a aplicação. Aplicações no toco de aminocyclopyrachlor e picloram e foliares de aminocyclopyrachlor + metsulfuron-methyl e glyphosate foram eficazes no controle de T. stans. / Pasture lands degradation is one of the largest problems of cattle livestock in Brazil. The development of pasture lands and its consequent inadequate management are factors that favor weed proliferation, diminishing forage grass productivity. Tecoma stans, is a difficult to control widespread weed in pasture lands since resprouts vigorously and quickly after the stalk is cut hindering its control by mechanical means. In order to find chemical alternatives to control the species and to identify the environmental factors that contribute to its germination and emergence, this study analyzed light and temperature effects on germination and seeding depth effect on the emergence of T. stans. Moreover, was analyzed the absorption, translocation and efficacy of aminocyclopyrachlor. In order to analyze the light effect, the seeds were distributed in clear and dark plastic boxes that were kept in a germination chamber in constant and alternated temperatures. The temperature effect was assessed in nine temperature intervals ranging from 15 to 40°C. In order to analyze seeding depth effect in seedlings emergence, the seeds were sowed at 0, 20, 40 and 80 mm. Absorption and translocation of 14C-aminocyclopyrachlor were analyzed over time in young T. stans plants. Field experiments were conducted applying aminocyclopyrachlor and picloram in the cut-stump and foliar applications of aminocyclopyrachlor + metsulfuron-methyl and glyphosate. Light and temperature experiments allowed to conclude that the species is neutral photoblastic and that the temperatures used in the experiments did not limit the species germination, since there were germination in 50% of the cases. When the seeds were applied in the soil surface there was a higher index of emergence, however, when the seeds were at 40 and 80 mm depth, the plant did not emerge. Twenty percent of the 14Caminocyclopyrachlor dosage applied was absorbed by T. stans leaves. Translocation percentage did not surpass 5% of the dosage applied after 72 hours. Aminocyclopyrachlor and picloram cut-stump applications as well as aminocyclopyrachlor + metsulfuron-methyl and glyphosate foliar applications were efficacy to control T. stans.

The work of my MFA thesis exhibition comes directly out of the physical processes that constitute my studio practice. It is work that embodies the labour of my hands and the decisions that guided them in their struggle with unfamiliar materials. Drawing inspiration from subjects as diverse as physics and fiction to create a sculptural arrangement, the work is intended to engage with its audience in an active way through acoustic appropriation and physical presence. As an artist, I set up an environment to be explored, establishing boundaries and also possibilities.

During the mid 1960s, record producers and jazz critics coined the phrase Sidewinder Syndrome to describe the funky style of music popularized through the success of Lee Morgan's solo release of "Sidewinder. The funky style, rooted in the heart of the hard bop period (1955-1965), united jazz, Latin influences, and popular black traditions such as gospel and urban blues. Lee Morgan (1938-1973), composer of "Sidewinder," and Richard "Blue" Mitchell (1930-1979) were two prolific trumpet artists from this time period who embraced the Sidewinder Syndrome, and as a result provided a rich improvisational vocabulary, as it pertains to trumpet performance practice. This study presents six annotated transcriptions from each artist focusing on elements of jazz vocabulary and solo construction.The study reveals vocabulary and solo construction preferences within the Sidewinder Syndrome. Results indicated the three most common harmonic generalization elements were digital patterns, change-running, and the bar-line shift. Complex harmonic generalization elements included bebop scale, 3-b9 movement, linear chromaticism, and tri-tone substitution / altered dominant. Vocal inflections derived from gospel music and urban blues were the half-valve, grace note, alternate fingerings, note bending, and fall. Bebop influenced articulation included upbeat-to-downbeat articulation and ghost note. Bebop influenced ornamentation included the two-sixteenth note ornament and the turn. Results suggest solo construction relied heavily upon the sequencing of rhythmic and melodic motives. Space was utilized for clarity, new concepts, and octave displacement. Developmental concepts included running eighth and sixteenth note lines. This study provides an opportunity for students of improvisation to isolate and study jazz vocabulary and solo construction of the Sidewinder Syndrome. / School of Music

The study of wave production and propagation is a common phenomenon seen within a variety of math and physics problems. This thesis in particular will investigate the production and propagation of sound waves through musical instruments. Although this field of work has been examined since the late 1800s, approaching these types of problems can be very difficult. With the exception of the last fifty years, we have only been able to approach such problems by linearizing the necessary equations of gas dynamics. Without the use of a computer, one can only get so far in studying nonlinear acoustic problems. In addition, the numerical theory for nonlinear problems is incomplete. Proving stability is challenging and there are a variety of open problems within this field. This thesis will be examining the propagation of sound waves specifically through brass instruments. However, we will not be able to fully examine this problem in a master’s thesis because of the complexity. Instead, the objective is to provide a foundation and global picture of this problem by merge the fields of nonlinear acoustics as well as computational and analytical gas dynamics. To study the general behaviour of nonlinear wave propagation (and to verify previous findings), experiments have been carried on a trumpet. The purpose of these experiments is take measurements of the sound pressure waves at various locations along the instrument in order to understand the evolution of the wave propagation. In particular, we want to establish if the nonlinear distortion is strong enough to have musical consequences; and if there are such outcomes, what prerequisites are required for the observable behaviour. Additionally, by using the discontinuous Galerkin numerical method, a model of the system will be presented in this thesis. It will then be compared with the experimental data to verify how well we were able to describe the nonlinear wave motion within a trumpet.

This is a qualitative research with three subjects, which are important soloists, teachers and orchestral musicians in the nacional scenario. The focus of the first chapter is mainly the technical-interpretative problems found in the performance of the concerto and the technical fundaments of the trumpet. On the second chapter it is included a biography of the composer, historical data of his work and the explanation of the technical-interpretative questions presented to the subjects. It is also in this chapter that the technical-interpretative questions, which were presented to the subjects to answer, are explained. The third chapter has a description of the methodology of the research, which was based in structured questionnaires that were answered by the subjects. The third chapter finishes with the comparison and analysis of the obtained answers. The dissertation ends with the final considerations, which demonstrates the importance of the performer when looking to the score and constructing the musical speech. Between the three subjects, it can be seen not only differences, but also many common points. The main objective of this study is to build interpretative questions that might be found in the Concerto and how the three professors think about these questions and pursue to solve them. From the crossing and analysis of their answers, we seek to achieve a broader view of the piece, and finally the possible solutions of its technical-interpretative questions. / Este trabalho destina-se ao estudo interpretativo do Concerto para Trompete e Orquestra de Cordas do compositor Alfredo Silveira Dias Filho.

No primeiro capítulo serão abordados fundamentalmente problemas técnico interpretativos na performance do concerto e os fundamentos técnicos do instrumento. No segundo capítulo encontra-se uma biografia do autor, dados históricos de sua obra e estão explicadas as questões técnico-interpretativas apresentadas aos sujeitos de pesquisa. O terceiro capítulo possui uma descrição da metodologia da pesquisa, a qual se utilizou de questionários estruturados que foram respondidos pelos sujeitos. Ainda neste capítulo encontra-se a comparação e análise das respostas obtidas. A dissertação se encerra com as considerações finais sobre a importância do olhar do intérprete sobre a partitura e como a construção do discurso musical entre os três sujeitos apresenta além de divergências, muitos pontos em comum. Buscou-se como objetivo principal desta dissertação fazer um levantamento das questões interpretativas que podem ser encontradas no Concerto e como três músicos profissionais pensam estas questões e procuram resolvê-las. Do cruzamento e análise das respostas procura-se ter uma visão mais ampla da obra e das possíveis soluções de suas questões técnico-interpretativas.
