Orientador: Prof. Dr. Maurício DottoriDissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências Humanas, Letras e Artes, Programa de Pós-Graduação em Música. Defesa: Curitiba, 31/08/2010Bibliografia: fls. 359-364Resumo: Esta dissertação apresenta materiais musicais gauchescos, coletados e analisados através de gravações com músicos inseridos no fazer musical do estado do Rio Grande do Sul, e a utilização destes materiais numa composição contemporânea. Para tanto, aborda primeiramente questões pertinentes ao folclore em geral, ao folclore musical gaúcho, e à apreensão de elementos musicais gauchescos para utilização composicional contemporânea. A seguir apresenta as transcrições destes materiais e a análise dos mesmos, pertencentes aos gêneros musicais chamarra, chote, vaneira, chamamé, rancheira, milonga, polca paraguaia e bugio, utilizados no Rio grande do Sul. Ligada à questão da utilização de materiais musicais gauchescos numa composição contemporânea, propõe-se uma definição instrumental de gesto musical, a qual se mostra bastante importante nesta transferência. Então é apresentada a composição de ensaio Rinascita, onde técnicas compositivas contemporâneas e o conceito de gesto musical, aplicados aos materiais coletados, foram experimentados pela primeira vez. Após, segue a composição principal, O rio de São Pedro, que busca demonstrar no âmbito da prática a elaboração teórica proposta. A composição, para grupo de câmara, é construída a partir da utilização de materiais musicais gauchescos e emprega um pensamento gestual. Um memorial da composição é então apresentado, no qual são descritos as técnicas compositivas e os principais gestos musicais utilizados, além de exemplos, retirados da partitura, da aplicação de várias questões derivadas das já discutidas. Encerra-se com as considerações finais, que avaliam tanto a elaboração teórica quanto a composição, na busca por uma validação, na prática da composição, do caminho teórico proposto.Abstract: This dissertation presents music materials originated in the gaucho cultural traditions of Rio Grande do Sul state, Brazil, collected and analyzed by means of recordings done with practical musicians there, and the use of these materials in a contemporary art-music composition. It deals, firstly, with subjects related to folklore in general, to gaucho folklore, and to the extraction of gaucho musical elements and their utilization in contemporary composition. Secondly, it presents the transcription and analysis of materials belonging to the chamarra, chote, vaneira, chamamé, rancheira, milonga, polca paraguaia and bugio musical genres, as found in Rio Grande do Sul. Related to the issue of using gaucho musical materials in a contemporary composition, an instrumental definition of musical gesture is proposed, which shows itself to be very important to this transfer. An essay piece, Rinascita, is presented, in which the composition techniques and the concept of musical gesture, as applied to the collected materials, were tried for the first time. Following, the main composition, O rio de São Pedro, that intends to put into practice the theoretical frame proposed. The composition, for a chamber group, was build from gaucho musical materials using a gestual thinking. Then, a composition memorial is presented in which the compositional techniques and the main musical gestures used are described, together with instances, drawn from the score, of application of the several issues derived from the already discussed. Finally, there is a discussion and assessment of the validity of the theoretical elaboration and of the composition

Ares de milonga: apontamentos sobre elementos característicos como bases para peformance

Este trabalho pretende apresentar algumas características do gênero musical milonga. O objetivo principal reside em estabelecer alguns apontamentos que possam servir como subsídios básicos para o intérprete que pretende abordar tal gênero, numa espécie de performance culturalmente informada, baseada no conceito de performance histórica de Peter Walls. Primeiramente, são apresentadas informações de ordem cultural para uma contextualização inicial. Após, com ênfase em aspectos musicais, são trabalhados detalhadamente exemplos de três tipos de milonga, os quais partem da concepção do meio musical (músicos) no qual está inserida e que caracterizam este gênero. Para finalizar, são analisadas algumas características em amostras do repertório violonístico. Dessa forma, pretende-se contribuir com uma perspectiva interpretativa que dialogue aspectos culturais, técnico-musicais e analíticos como fonte de inspiração para novos milongueiros

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV

The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.
