The field of experience and reflection in this dissertation is the Pau and Lata: Artisticpedagogical project and its activities in the field of music education It was created in 1996, by the Community School Sementes da Luz, located on Tabuleiro do Martins district, Maceió / AL. The work extended to the Rio Grande do Norte and later returned to Alagoas, keeping their activities in both states, involving approximately 280 people. The issues that moved us front the experience of Pau e Lata were: What are the main references and theoretical-methodological elements that constitute the formation of the musician in Pau e Lata? How members perceive this project and include themselves in the educational process of music formation? How it works and what is the meaning of the use of instruments and the learning of musical writing and reading? These questions lead us to undertake this dissertation, in order to deepen reflection on the processes of musical training on Pau e Lata, relating the experiences of its members in the process and the theoretical references governing their educational practice. In this sense, we outline the research objectives, which are: describe the Pau e Lata project, focusing on their context of action and their methodological processes; investigate the relationship between the effective participation of its members in the process of composition of the artistic and pedagogical repertoire and its performance in the field of cultural militancy in the environment where it operates. The writing process of this research is based on the phenomenological perspective. Therefore constitute our methodological research path two roads that communicate: 1) the organization and description of historical record of Pau e Lata (supporting documents, certificates, posters, etc.) and memories of the researcher and from other members of the group. 2) the formation of focal groups and writing and sending, via online, testimonials the participants of Pau and Lata relating to issues scrap and onomatopoeia, respectively. Participated in this process 11 components, adding the presence of the researcher, with the age between 21-45 years, all members of Pau e Lata, Core UFRN. The results of this research are focused on the discussion of three axes that describe and guide the work of the Pau e Lata: collective work, the use of the scrap as instrument and the onomatopoeia as base of a methodological process of musical training. This score was composed of three parts. The first part is presented from a collection of references from Pau e Lata, composed of printed and videographic records. The second part refers to the instrument used by Pau e Lata, and the perception of group members on these instruments, which occurs so that they are integrated in the training of the musician.The third axis tells how and what it means learning of music writing and reading, that occurs in two related aspects: the teaching-learning process and the body as a musical element in this process, associated with other actions characterized as studies and theoretical deepening

Impactive contact between a vibrating string and a barrier is a strongly nonlinear phenomenon that presents several challenges in the design of numerical models for simulation and sound synthesis of musical string instruments. These are addressed here by applying Hamiltonian methods to incorporate distributed contact forces into a modal framework for discrete-time simulation of the dynamics of a stiff, damped string. The resulting algorithms have spectral accuracy, are unconditionally stable, and require solving a multivariate nonlinear equation that is guaranteed to have a unique solution. Exemplifying results are presented and discussed in terms of accuracy, convergence, and spurious high-frequency oscillations.

I believe that the purpose of expanding the oboe’s repertoire is to not only create original compositions, but to also utilize technical advancements in order to achieve access to a wider range of repertoire through the art of transcription. This paper examines the various paths to achieving such expansion, including utilizing unique performer skills, use of auxiliary instruments, advancements in the instrument itself and musical developments that challenge the perception of the oboe’s solo role in a particular era of music history. The oboe need not be relegated to the confines of a compositionally limited stereotype. The goal of my “extended-range” dissertation project is to expand the “range” of programmable repertoire, with a focus on music in both the 19th and 21st-centuries, while simultaneously expanding the technical capabilities and expectations of the modern oboe—in part by exploiting the new possibilities of the recently invented low-A extension key.

All history of the flute in Scotland begins with William Tytler’s 1792 assertion that the flute was unknown in Scotland prior to 1725. Other generally accepted beliefs about the flute in Scotland are that it was only played by wealthy male amateurs and had no role in traditional music. Upon examination, all of these beliefs are false. This thesis explores the role of the flute in eighteenth-century Scottish musical life, including players, repertoire, manuscripts, and instruments. Evidence for ladies having played flute is also examined, as are possible connections between flute playing and bagpipe playing. What emerges is a more complete picture of the flute’s role in eighteenth-century Scottish musical life.

Abstract In the current historiographical production there is a manifest interest for the history of female religiosity. The mystic phenomenon, the everyday life and the temporal dimension of the communities, in terms of familiar and social connection to the outside of cloistered spaces, manifestations of creativity and culture, are increasingly treated issues. This interest is also expressed about the Cistercian Order in Portugal. In the female branch, the monastery of St. Benedict of Cástris, officially Cistercian for more than 700 years, has been the target of an interdisciplinary approach that intents to appreciate the impact of the reflections of the Council of Trent in the musical praxis of the nuns. This community, subject to Alcobaça and controlled through Visitors, registers in its documentation not only the presence of nuns that sang and played various instruments, arising mainly from Évora region, a city with a recognized musical tradition, but also registers various expenses related with the musical practice of the monastery. Resumo Regista-se, na actual produção historiográfica, um interesse manifesto pela história da religiosidade feminina. O fenómeno místico, o viver quotidiano e a dimensão temporal das comunidades, em termos de ligação familiar e social ao exterior dos espaços-clausura, as manifestações de criatividade e cultura, são questões cada vez mais tratadas. Esse interesse manifesta-se também para a Ordem de Cister em Portugal, sendo que, no ramo feminino, o mosteiro de S. Bento de Cástris, oficialmente cisterciense há mais de 700 anos, vem sendo alvo de uma abordagem multidisciplinar que procura apreciar os reflexos do Concílio de Trento na praxis musical das religiosas. Esta comunidade, sujeita a Alcobaça e por ela controlada através dos Visitadores, regista na sua documentação não só a presença de religiosas cantoras e tangedoras de vários instrumentos, oriundas maioritariamente da região de Évora, cidade com uma tradição musical reconhecida, como diversas despesas relacionadas com a prática musical do mosteiro.

Measurement instruments are an integral part of clinical practice, health evaluation and research. These instruments are only useful and able to present scientifically robust results when they are developed properly and have appropriate psychometric properties. Despite the significant increase of rating scales, the literature suggests that many of them have not been adequately developed and validated. The scope of this study was to conduct a narrative review on the process of developing new measurement instruments and to present some tools which can be used in some stages of the development process. The steps described were: I-The establishment of a conceptual framework, and the definition of the objectives of the instrument and the population involved; II-Development of the items and of the response scales; III-Selection and organization of the items and structuring of the instrument; IV-Content validity, V-Pre-test. This study also included a brief discussion on the evaluation of the psychometric properties due to their importance for the instruments to be accepted and acknowledged in both scientific and clinical environments.

The cleaning capacity of Hero 642 nickel-titanium files, complemented by the Hero Apical instruments in flattened roots, was determined by histological analysis, considering the area of action of the instruments on the coronal walls and the presence of remaining debris. Twenty-four single-canal, human mandibular incisors were divided into three groups and prepared as follows: GI, instrumented with Hero 642 NiTi files 30/.06, 25/.06, 20/.06, 25/.06, and 30/.06; GII, instrumented as GI followed by Hero Apical size 30/.06; GIII, instrumented as GI followed by Hero Apical sizes 30/.06 and 30/.08, then returning to 30/.06 with pendulum movements. The apical thirds were prepared for histological processing, analyzed at 40× magnification and the images were examined morphometrically. Statistical analysis showed that GIII presented the best results for removing debris (5.22% ± 4.13), with more contact between the instruments and the root canal walls (19.31% ± 0.15). This differed statistically from GI (14.04% ± 4.96 debris removal, with 42.96% ± 7.11 instrument contact) and GII (12.62% ± 5.76 debris removal, with 35.01% ± 0.15 instrument contact). Root canal preparation with Hero 642, complemented by Hero Apical instruments (30/.06 and 30/.08, then re-instrumented with Hero Apical 30/.06 using pendulum movements), was more efficient for debris removal and allowed more contact of the instruments with the root canal walls. GII presented the worst results.

SEVERAL MODELS OF TIME ESTIMATION HAVE BEEN developed in psychology; a few have been applied to music. In the present study, we assess the influence of the distances travelled through pitch space on retrospective time estimation. Participants listened to an isochronous chord sequence of 20-s duration. They were unexpectedly asked to reproduce the time interval of the sequence. The harmonic structure of the stimulus was manipulated so that the sequence either remained in the same key (CC) or travelled through a closely related key (CFC) or distant key (CGbC). Estimated times were shortened when the sequence modulated to a very distant key. This finding is discussed in light of Lerdahl's Tonal Pitch Space Theory (2001), Firmino and Bueno's Expected Development Fraction Model (in press), and models of time estimation.

Online music databases have increased significantly as a consequence of the rapid growth of the Internet and digital audio, requiring the development of faster and more efficient tools for music content analysis. Musical genres are widely used to organize music collections. In this paper, the problem of automatic single and multi-label music genre classification is addressed by exploring rhythm-based features obtained from a respective complex network representation. A Markov model is built in order to analyse the temporal sequence of rhythmic notation events. Feature analysis is performed by using two multi-variate statistical approaches: principal components analysis (unsupervised) and linear discriminant analysis (supervised). Similarly, two classifiers are applied in order to identify the category of rhythms: parametric Bayesian classifier under the Gaussian hypothesis (supervised) and agglomerative hierarchical clustering (unsupervised). Qualitative results obtained by using the kappa coefficient and the obtained clusters corroborated the effectiveness of the proposed method.

This work proposes an association between musical analysis techniques developed during the twentieth and the twenty-first centuries, presented by authors like Felix Salzer and Joseph Straus, and the musical theory concepts presented by Olivier Messiaen, for the analysis of Prelude n(o) 1, La Colombe. The analysis contributes to broaden the theory concepts presented by the composer. In the Conclusion we trace lines of an authorial sonority by Olivier Messiaen.

Air transport has become a vital component of the global economy. However, greenhouse-gas emissions from this sector have a significant impact on global climate, being responsible for over 3.5% of all anthropogenic radiative forcing. Also, the accrued visibility of aircraft emissions greatly affects the public image of the industry. In this context, incentive-based regulations, in the form of price or quantity controls, can be envisaged as alternatives to mitigate these emissions. The use of environmental charges in air transport, and the inclusion of the sector in the European Union Emissions Trading Scheme (EU ETS), are considered under a range of scenarios. The impacts of these measures on demand are estimated, and results suggest that they are likely to be minimal-mainly due to the high willingness to pay for air transport. In particular, in the EU ETS scenario currently favoured by the EU, demand reductions are less than 2%. This may not be true in the longer run, for short trips, or if future caps become more stringent. Furthermore, given current estimates of the social Cost Of CO2 as well as typical EU ETS prices, supply-side abatement would be too costly to be encouraged by these policies in the short term. The magnitude of aviation CO2 emissions in the EU is estimated, both in physical and monetary terms; the results are consistent with Eurocontrol estimates and, for the EU-25, the total social cost of these emissions represents only 0.03% of the region`s GDP. It is concluded that the use of multisector policies, such as the EU ETS, is unsuitable for curbing emissions from air transport, and that stringent emission charges or an isolated ETS would be better instruments. However, the inclusion of aviation in the EU ETS has advantages under target-oriented post-2012 scenarios, such as policy-costs dilution, certainty in reductions, and flexibility in abatement allocation. This solution is also attractive to airlines, as it would improve their public image but require virtually no reduction of their own emissions, as they would be fully capable of passing on policy costs to their customers.
