António Pinho Vargas: uma caracterização musical. Inter-relações estéticas e técnicas com a música do próprio autor
No full textEste Trabalho de Projeto é constituído por uma parte de Dissertação e outra de criação musical do seu autor. É elaborado um estudo da música de António Pinho Vargas, nas suas várias vertentes, com vista a uma sua caracterização global. Dá-se enfoque às características diatónicas tonais/modais presentes na maioria da sua música da vertente erudita contemporânea. Estabelecem-se inter-relações estéticas e técnicas entre Pinho Vargas e a música do autor do trabalho, no sentido de, através de um compositor com o qual tem uma identificação musical significativa em vários domínios, contribuir para o estabelecimento da sua identidade enquanto compositor em formação. São assim suscitadas algumas reflexões em torno de questões estéticas e técnicas a nível da composição musical. Deste trabalho faz parte um dossier reunindo as obras do autor realizadas ao longo do curso de Mestrado que se adequam ao tema do Trabalho de Projeto, ao qual se junta um CD áudio contendo estas peças, algumas interpretadas por músicos, outras com som sintetizado; António Pinho Vargas - A musical characterization. ### Aesthetical and technical interrelations with the music of the author himself.
ABSTRACT
:This work is comprised of two parts, a dissertation and a musical composition by the author. A study of the music of Antonio Pinho Vargas, in its different shapes, is elaborated, aiming at a global characterization. The focus is on the diatonic tonal/modal characteristics present in the majority of his contemporary erudite compositions. Aesthetical and technical interrelations are established between Pinho Vargas and the music of the author so as to contribute to establish an identity as a forming composer, through a composer with whom the author has a significant musical identification in several domains. Some reflections are thus raised, around aesthetical and technical matters of music composition. As part of this work, a compilation of the music composed by the author throughout the time of his Master’s degree that fit its project theme and an audio cd with this pieces are given, some of this played by musicians, others with synthesized sound

criações musicais; ABSTRACT: “Idiomatic Writing for Guitar in Contemporary Music”
The present Project aims to define what can be regarded as idiomatic composition for
guitar, in order to systematise rules and techniques that may assist the production of
written music for this instrument.
After an initial approach to the instrument’s characteristics, the author analyses some
of its inherent qualities, and enumerates idiomatic features of the classical-romantic
tradition.
The analysis of XX and XXI century repertoire, as well as the bibliographic research,
the interviews with experienced guitarists, and the study of original works composed by
the author, attempt to provide a thorough understanding of the potential of the guitar,
exemplifying a number of idiomatic features of contemporary writing. These can
enhance the quality of the musical discourse and may benefit composers who are
interested in writing for this instrument
Braga Santos: Concerto, Sinfonietta e Divertimento II para orquestra de cordas
No full textEsta tese apresenta o estudo, a revisão e a edição de três obras para
orquestra de cordas de Joly Braga Santos (JBS): o Concerto para Orquestra de
Cordas, op. 17, a Sinfonietta para Orquestra de Cordas, op. 35 e o Divertimento
II para Orquestra de Cordas, op. 52. Tendo como base a pesquisa e análise dos
manuscritos existentes, o objetivo principal deste estudo visa a construção de
uma revisão e edição das três peças, fundamentada num contexto bibliográfico
existente. O meio musical português coabita ainda, apesar do seu grande
crescimento nas últimas décadas, com algumas lacunas graves no que diz
respeito à acessibilidade em boas condições às partituras e materiais de
orquestra de variadíssimos compositores. O presente trabalho é um pequeno
impulso, para que as obras em estudo sejam melhor conhecidas e
reconhecidas, permitindo, na hora da sua interpretação, uma mais fácil e
melhor abordagem das mesmas, contribuindo assim para uma crescente
maturação no que diz respeito à sua compreensão e interpretação; Abstract:
Braga Santos: Concerto, Sinfonietta and Divertimento II for string orchestra
Author: Pedro Miguel Pires de Oliveira Neves
This thesis presents the study, revision and edition of three pieces for
string orchestra by Joly Braga Santos (JBS): the Concerto for String Orchestra,
op. 17, the Sinfonietta for String Orchestra, op. 35 and the Divertimento II for
String Orchestra, op. 52. The main objective of this study is to create a revised
edition of the three pieces, based on research and analysis of existing
manuscripts and existing bibliographic material. Despite great improvement
over the last decades, there is still a serious lack of availability of scores and
orchestral material in good condition. The aim of this thesis is to raise
awareness and recognition of the above mentioned works. In addition, it will also
allow a deeper understanding of the scores, which will result in more accurate
and educated interpretation
Peter Scazzero. Emotionally Healthy Spirituality. It’s Impossible to be Spiritually Mature, while Remaining Emotionally Immature. Updated edi-tion. Grand Rapids: Zondervan, 2017. 240 pp. (review)
No full textThe author is a Baptist pastor with Italian roots and a well-known writer on both sides of the Atlantic in the realm of Christian spirituality. The book cover itself announces his success with the large heading “more than 500,000 sold,” raising both curiosity as well as concerned German eye brows wondering about the modesty of the author and/or the need of the publishing house to push the book. However, to be honest, American culture is very different in many ways. And that is well demonstrated throughout the whole book
Standards issues in data communications
No full textThe lack of development in standards and compatibility in the field of data communication and processing requires urgent attention. The author discusses the compatibility issues that arise from the introduction of packet-switching networks, which typify the growing interdependence of computer and communication technologies. Focusing on Canada as a case example, he examines issues relating to the compatibility between the communication services offered by different networks and communication functions used for distributed data processing, and also between the procedures employed to provide these services and functions.
História de uma gaivota e do gato que a ensinou a voar: a criação de música para crianças como parte de uma ética artística e social
No full textTese de doutoramento em Estudos da Criança (área de especialização em Educação Musical)O presente trabalho, “História de uma Gaivota e do Gato que a ensinou a Voar:
a criação de música para crianças como parte de uma ética artística e social”, tem
como objectivos principais a investigação do contexto político, social e ético no qual
as formas melodramáticas da música para crianças no século XX foram criadas (conto
musical e outros), com especial ênfase na primeira metade do século, época durante a
qual esta problemática tomou forma e se revelou mais acutilante, e a análise de uma
obra do autor que se insere no género melodramático, a História de uma Gaivota e do
Gato que a ensinou a Voar (texto de Luis Sepúlveda e música de Sérgio Azevedo),
análise cuja função fundamental consiste em fornecer ferramentas de reflexão sobre as
questões levantadas na investigação histórica preliminar. Este trabalho procura também colmatar em parte a falta de estudos sobre esta
problemática específica, tendo-se verificado que a bibliografia publicada, se
abundante no que respeita ao primeiro dos dois temas – contexto político das artes no
século XX –, é muito escassa no que respeita à história e análise da música para
crianças no século XX, e praticamente inexistente no que respeita à ligação entre
ambos. Este facto revela a “menoridade” com que o género continua a ser encarado,
regendo-se a investigação por critérios históricos e analíticos que visam contrariar
este preconceito longamente estabelecido Para atingir estes objectivos o trabalho foi dividido em duas partes:
investigação histórica do contexto social e político da música melodramática para
crianças no século XX, na qual os principais compositores, contextos políticos e
movimentos estéticos relacionados com o tema são estudados, e análise detalhada dos
aspectos literários e musicais da História de uma Gaivota e do Gato que a ensinou a
Voar. Desta análise, que leva em conta as conclusões originadas pela investigação
histórica da primeira parte, resulta a fundamentação da posição do autor em relação ao
que este crê dever ser a música para crianças: um género maior, que pode contribuir
para o enriquecimento não só do ser humano numa fase de formação da personalidade
e intelecto, mas também possuir o poder de interessar o adulto já formado, num
contexto de plena liberdade estética e ideológica.The principal objectives of this thesis, “The story of a seagull and the cat that
taught it to fly: the creation of music for children as part of artistic and social ethics”,
are the research of the political, social and ethical context in which musical
melodrama for children of the 20th century (music tales and others) was created, with
special emphasis on the first half of the century during which the problem was formed
and became more acute, and the analysis of a work written in this genre by the author,
The story of a seagull and the cat that taught it to fly (story by Luis Sepúlveda and
music by Sérgio Azevedo), that provides a means of reflection on the questions raised
by the initial historical research. This thesis also aims to fill the gap, at least in part, left by the lack of study of
this particular subject. The first of the two themes – the political context of the arts in
the 20th century – is dealt with extensively; the bibliography for second – history and
analysis of the music written for children in the 20th century – is very sparse;
treatment of the relationship between the two is virtually non-existent. This fact
demonstrates the dismissive way in which the subject continues to be treated, and this
research is carried out with the intention of setting straight this long-held
preconception. To reach these goals the thesis has been divided into two parts: research into
the social and political context of musical melodrama for children in the 20th century,
in which the principal composers, political contexts and aesthetic movements related
to the subject are studied, and a detailed analysis of literary and musical aspects of
The story of a seagull and the cat that taught it to fly. This analysis takes into account
the conclusions drawn from the historical research of the first part and results in the
fundaments of the composer’s belief as to what music for children should be: an
important genre that not only contributes to the enrichment of a human being at a
stage when his personality and intellect are still being formed, but also has the
capacity to interest the fully formed adult listener in a context of total aesthetic and
ideological freedom
Evaluation of psychological interventions to reduce cigarette littering
No full textIn the planned online study two intervention techniques for the reduction of cigarette littering are to be evaluated in a randomised controlled trial. Cigarette littering means the incorrect disposal of cigarettes outside rubbish bins and ashtrays. For this purpose, two experimental groups (EG1, EG2) and one control group (CG) are chosen. On the theoretical basis of the slightly adapted Extended Model of Normative Decision Making (Klöckner & Matthies, 2004) relevant behavioural factors were determined and according to that suitable intervention techniques were selected based on Mosler und Tobias (2007). In the EG1 a factual text and matching pictures will be used for the provision of information referring to problem- and action-knowledge on the environmental issues of cigarette littering. In the EG2 prompts (‘Cigarette in the bin please!’) are placed on bins in four of five hypothetical scenarios. Cigarette littering will be measured also by using the five hypothetical scenarios. The participants are asked to indicate how likely they are to choose the disposal options shown (rubbish bin/ashtray, floor, other disposal options, etc.) on pictorial cut outs from the scenarios. Established scales were adapted and will be used to assess behaviourally relevant psychological constructs from the model (awareness of need, awareness of consequences, perceived behavioral control, personal norm, social norm, habits) and for other constructs
Voice Compression and Communications: Principles and Applications for Fixes and Wireless Channels
No full textUp-to-date, expert coverage of topics in wireless voice communications Voice communication is the most important facet of mobile radio service. Even when the predicted surge of wireless data and Internet services becomes a reality, voice will remain the most natural means of human communication. Voice Compression and Communications details issues in wireless voice communications and treats compression, channel coding, and wireless transmission as a joint subject. Part I covers background material, whereas Part II provides detailed information on both proprietary and standardized analysis-by-synthesis codecs, including the speech codecs of virtually all existing wireline-based and wireless systems. Parts III and IV discuss mainly research-based wideband, audio, as well as very low-rate schemes likely to find their way into future standards. Voice Compression and Communications describes fundamental concepts in a non-mathematical way early in the book for those with only a background knowledge of signal processing and communications. More advanced readers will find detailed discussions of theoretical principles, future concepts, and solutions to various specific wireless voice communications problems
Jeux d’anches - Accordionistic musical education through musical performance
No full textDesde a segunda metade do século XX, com a invenção do sistema conversor, a escrita original para acordeão surgiu, gerando novos desafios para intérpretes, compositores e para o próprio instrumento. Obviamente, para abordar novas obras, os músicos têm alcançado níveis cada vez mais rigorosos, disciplinados e transversais de preparação e conhecimento musical, a fim de atingir habilidades de linguagem e técnica contemporâneas. Nesse contexto, há um vasto repertório de novas obras, como: Berio Sequenze, Gubaidulina De Profundis, Bochmann Essay XVIII, entre outras, cuja contribuição para o ensino de música e a prática instrumental tem um papel determinante nos campos pedagógico e performático. A peça Jeux d’Anches, composta por Magnus Lindberg, também está na lista como uma importante contribuição para explorar o instrumento (acordeão) na dimensão e potencial de alto nível. Através deste artigo, o autor pretende refletir sobre a educação musical acordeonística, introduzir novas possibilidades de execução e discutir novas técnicas de escrita para acordeão clássico.Since the second half of the XX century, with the invention of the converter system, original writing for accordion has come, generating new challenges to interpreters, composers and the instrument itself. Obviously, to approach new works, musicians have been achieving increasingly strict, disciplined and transversal levels of musical preparation and knowledgement in order to achieve contemporary language and technique skills. In this context, there is a vast repertoire of new works, such as: Berio Sequenze, Gubaidulina De Profundis, Bochmann Essay XVIII, among others, whose contribution to the music teaching and instrumental practice has a determinant role in the pedagogical and performance fields. The piece Jeux d’Anches, composed by Magnus Lindberg, is also on the list as an important contribut to explore the instrument (accordion) in the high level dimension and potential. Through this article, the author pretends to reflect about the accordionistic musical education, to introduce new performance possibilities and to discuss new writing techniques for classical accordion.CESEM - Centro de Estudos em Músic
