The Interloping Beguiler: for Bass Clarinet and Orchestra

The Interloping Beguiler is an nineteen-minute concerto in four movements for bass clarinet solo and orchestra. The title refers to the role of the solo instrument, which continually thrusts itself into the affairs of the orchestra, deceiving and diverting the members of the orchestra away from their task of performing a "serious" orchestral composition. The bass clarinet portrays a comical, cartoon-like character whose awkward, and sometimes goofy, interjections cause chaos. Attempts are made by various members of the orchestra, especially the horns, to regain control of the work, but the bass clarinet always succeeds in its distracting antics. By the final movement of the composition, the bass clarinet has propelled the work into a cartoon-like landscape of quickly changing textures, dissonant intervals, and overlapping themes. The first movement, Introduction, sets the serious tone of the music to follow, or so it would seem. The entrance of the bass clarinet immediately changes this texture with its out-of-rhythm alternations between high and low pitches. This gesture provides a glimpse into the personality of the bass clarinet, an instrument here to mislead the members of the orchestra. Deception truly begins in the second movement, The Interloping Initiates. The bass clarinet starts the movement with a driving theme and is immediately supported by the orchestra. As the movement progresses, the bass clarinet quickly begins altering the theme, making it more playful and cartoonish. A struggle ensues between the horns and the bass clarinet, with the bass clarinet catapulting the piece into a latin-inspired section. The struggle continues through to the end of the movement. The third movement, Calm, is exactly what the title suggests. A sectional form distinguishes this movement from the second movement. Throughout Calm, the bass clarinet behaves with decorum, except for very large melodic leaps. The seed of anarchy planted by the bass clarinet in the second movement comes to fruition in the final movement, The Beguiling Builds. Here, the bass clarinet sends the work into chaos with sections recalling Looney Tunes cartoons, Hollywood western music, and children's folk songs.

EARLY TWENTIETH CENTURY VIOLA MUSIC FROM ENGLAND AND GERMANY: FROM POST-ROMANTICISM TO MODERNISM

In the early twentieth century, the viola began to gain status as a solo instrument with the appearance in England of the virtuosic violist Lionel Tertis. Because of a lack of music for viola at that time, such English composers as York Bowen, Arnold Bax, Ralph Vaughan Williams, Arthur Bliss and William Walton began to write viola music for Tertis. Meanwhile, in Germany, the well-known composer and virtuosic violinist and violist Paul Hindemith wrote and premiered several viola sonatas and concertos. Viola music became even more developed later with William Primrose, the legendary Scottish violist, and all the works written in the early twentieth century have remained significant in the viola literature. Although this new viola music appeared in both countries during same period, it developed along different lines in each country. Because they were under the influence of earlier periods and traditions, the English composers who associated with Tertis wrote their music in a Romantic style, with expanded harmony, various colors of sound and timbre, and lyrical melodies. Hindemith, as a composer himself, employed a more Modernist style, using atonality and angular melodies, which represented German trends at that time. I have given three recitals, of which the first two were divided between selected English music and German music. Although I originally intended to focus solely on music by Hindemith and music written for Terts, I decided that in order to give a more complete view of the national trends of those two countries, I included Rebecca Clarke's Sonata, Lachrymae by Benjamin Britten (dedicated to William Primrose), and Max Reger's Suite for Viola. Rebecca Clarke was herself a fine violist, and her sonata's Romantic style is also representative of the English trends of viola music. Lachrymae was written with a different concept and shows more modernity than had ever before occurred in England, though it still differs from the modernity of other countries. Max Reger's Suite is in a truly Romantic style, yet it is old fashioned in ways that differ not only from Wagner or Strauss, but also from English music of the period. In my last recital I wished to pay homage to Tertis, with a program consisting entirely of music written for him. For the finale, Arthur Bliss's Viola Sonata was especially chosen because it provides interesting similarities and contrasts with earlier English music in the Romantic style.

LIONEL TERTIS AND THE FLOWERING OF EARLY TWENTIETH CENTURY ENGLISH VIOLA REPERTOIRE

This performance project focused on English viola literature written in the first half of the twentieth century. During this time, numerous English composers were influenced by Lionel Tertis' unprecedented approach to the viola as a virtuosic and solo instrument. In addition to being an inspiration to composers of whom he was not in direct contact, Tertis' innovative vision for the viola led to numerous collaborations with prominent English composers of his generation. Ralph Vaughan Williams, Arnold Bax, York Bowen, Frank Bridge, Benjamin Britten, and Rebecca Clarke -his own protégé - composed some of the most important works for viola thus directly shaping the impression of the instrument as we know it today. Tertis' artistry as a performing violist was unmatched at the beginning of the twentieth century. He had a unique approach to the instrument which focused on concept of sound, tone color, concentrated listening, continuous vibrato, discreet portamento, and expressive interpretation. His convincing musical and technical ideas led him to write a treatise about how to achieve a beautiful tone. His passion for teaching and concern for the viola's posterity greatly enhanced the development of the viola. Tertis transcribed, edited, and premiered many works during his career. The music that Lionel Tertis influenced can be seen as a microcosm for a musical resurgence in England during the first half of the twentieth-century. The catalyst for this was artistic influences in the form of nationalism, folk music, romanticism, modernism, and impressionism, among others. Before this, England was widely referred to as ''the land without music" but in a very real sense, .Lionel Tertis was one of the pioneers who, through his artistry of the viola, led the way to the renaissance of music in England in the twentieth century.

THE DISTINCTIVE VOICE OF PAUL HINDEMITH THROUGH THE VIOLA

Paul Hindemith has made numerous contributions to the viola, both as a composer and performer. As a composer, he has written 7 sonatas for the viola, as well as a number of chamber and orchestral works which feature the viola as a solo instrument. As a violist, Hindemith was one of the only virtuoso soloists of his lifetime, and premiered virtually all of his solo compositions. Many of his pieces remain an integral part of the viola repertoire; Der Schwanendreher is one of the three major Twentieth-Century concertos for the viola. While some of his pieces are well-known, there are many others which are not performed with much frequency, due in part to the sheer output of this prolific composer. In this dissertation project, I performed Hindemith's compositions for the viola as a solo instrument. Consideration was given to exclusively performing his 4 solo sonatas and 3 sonatas for viola and piano. His only viola duet, his only non-sonata written for viola and piano, and 2 of his viola concertos (Der Schwanendreher and Trauermusik) were included in this dissertation project to provide contrast and supplement the three recital programs. Through this dissertation project I have been able to gain a deeper understanding of the complex language of Hindemith and interpret his music in an approach that is accessible to both the performer and the audience. All performances took place in the Gildenhom Recital Hall and Ulrich Recital Hall at the University of Maryland. All collaborations with piano were performed with Eliza Ching. The Duett for Viola and Violoncello was performed with Daniel Shomper, and the assisting musicians performing in the Trauermusik were Joel Ciaccio, Daniel Sender, Daniel Shomper, Cassandra Stephenson and Dana Weiderhold.

Polysaccharide co-polymerases:the enigmatic conductors of the O-antigen assembly orchestra

The O-antigen lipopolysaccharides on bacterial surface contain variable number of oligosaccharide repeat units with their length having a modal distribution specific to the bacterial strain. The polysaccharide length distribution is controlled by the proteins called polysaccharide co-polymerases (PCPs), which are embedded in the inner membrane in Gram-negative bacteria and form homo oligomers. The 3D structures of periplasmic domains of several PCPs have been determined and provided the first insights into the possible mechanism of polysaccharide length determination mechanism. Here we review the current knowledge of structure and function of these polysaccharide length regulators.

Interacção entre estruturas intervalares e estruturas espectrais, na música instrumental/vocal

A presente tese apresenta-se num formato bipartido, sendo a primeira parte uma investigação teórica e a segunda parte um conjunto de composições originais que procuram estabelecer, directa e indirectamente, uma relação com a temática investigada. A investigação incide sobre as diferentes relações que se podem estabelecer entre estruturas intervalares e estruturas espectrais, a partir de um conjunto representativo de obras de diferentes compositores. As obras originais da segunda parte configuram um objecto final de análise e reflexão. As composições que integram a segunda parte da tese são: Inês – sete miniaturas sobre A Castro, para soprano e orquestra, sobre excertos de “Castro”, de António Ferreira; Um sino contra o tempo, para flauta, clarinete, percussão e piano; Terra, para orquestra de cordas; Dor e Amor, para voz, flauta, clarinete, percussão, harpa, piano, violino, viola e violoncelo, sobre poemas de Nuno Júdice; e Ode a Gaia, para soprano solo, coro misto e electrónica, a partir de textos de diversos autores e épocas, desde Homero a Fernando Pessoa. Esta investigação surge a partir da convicção de que é possível e enriquecedor para a composição a coexistência e o estabelecimento de uma relação entre estruturas que valorizam as qualidades dos intervalos que as constituem e estruturas de tipo espectral. Se o pensamento intervalar pode ser relacionado com princípios de estruturação ligados a toda uma tradição musical, desde a música modal, à tonal e à atonal, o pensamento espectral relaciona-se com o estudo do fenómeno sonoro e do timbre e é integrado mais tardiamente no séc. XX como um possível modelo estruturante na composição. A investigação sobre as obras seleccionadas, sobretudo de compositores que colocam o fenómeno da percepção num plano central, procura diferentes interacções entre os dois tipos de estrutura, interrogando-se sobre em que medida é que essa interacção influencia ou é mesmo determinante para o resultado musical final. São analisadas diferentes aplicações, tais como: a procura de qualidades acústicas na criação de estruturas intervalares, a criação de timbres particulares para linhas estruturantes, a manipulação tímbrica de estruturas verticais, a inter-relação de camadas intervalares e espectrais na textura musical de forma sincrónica e diacrónica, e o surgimento de material intervalar a partir de estruturas espectrais. Os principais resultados passam pela confirmação de que o pensamento intervalar é compatível com o pensamento espectral e vice-versa, podendo-se concluir que são essenciais diferentes funções para os dois tipos de estrutura na textura musical e que quer as estruturas intervalares quer as espectrais se relacionam com diferentes aspectos da percepção, tendo, assim, uma influência determinante no resultado musical final, na eficácia da escuta e na sua fruição.

Principais dificuldades que os alunos de viola de arco apresentam quando ingressam no ensino superior português: relatório de estágio

A maioria dos instrumentistas de cordas friccionadas apresentam problemas ou dificuldades ao longo de toda a sua aprendizagem musical. Como professora e violetista, realizei este relatório de estágio com o intuito de pesquisar onde se focam a maioria desses problemas. Este relatório de estágio está dividido em duas diferentes secções, a primeira apresenta todo o trabalho pedagógico efectuado com três diferentes alunos, de diferentes níveis ao longo do ano lectivo de 2012/13 na Fundação Musical dos Amigos das Crianças (FMAC), e a segunda apresenta toda a investigação que realizei para concluir quais as principais dificuldades que os alunos de viola de arco apresentam quando ingressam no Ensino Superior. A investigação apresenta uma vasta pesquisa literária e o testemunho dos professores de várias instituições, como a Universidade do Minho, Escola Superior de Música e Artes de Espectáculo, Universidade de Aveiro, Escola Superior das Artes Aplicadas de Castelo Branco e Escola Superior de Música de Lisboa que ajudaram à profunda análise deste tema. Os resultados revelaram que os principais problemas apresentados nos estudantes de viola de arco são de origem técnica, ou seja, postura (posição do corpo, distribuição do peso correcto pelas pernas e escolha adequada do instrumento de acordo com a fisionomia do aluno); mão direita (pega correcta dos dedos no arco, distribuição de arco e contracção muscular); mão esquerda (posição do polegar, ombro e braço que afectam a afinação, flexibilidade, mudanças de posição e vibrato); influência da escolha do repertório por parte de um professor e autonomia do aluno.

Niagara Symphony Orchestra fonds, 1926, 1948-1998, n.d.

In 1948, The St. Catharines Civic Orchestra was founded by Jan Wolanek who was also the first conductor. Initially, this was a community orchestra and in 1963 its governing body assumed the name St. Catharines Symphony Association. In 1978 the name was again changed to The Niagara Symphony Association to reflect regional responsibilities. Wally Laughton was named Assistant Conductor in 1952/53. R.C. Clarke took over the orchestra for an interim period after Wolanek left in 1957. In 1958 Leonard Pearlman became the Music Director. It was under his direction that the Niagara Symphony Chorus came into existence in 1963. Milton Barnes succeeded Pearlman in 1964 and he was responsible for directing the symphony’s first opera production. He also made a concerted effort to attract younger people to symphonic music. In 1972 Leonard Atherton became the Music Director. He started the Cantata Choir and the Madrigal Singers. It was under his tenure that the orchestra became professional. When Atherton left in 1980, there were three seasons of guest conductors, the most notable of these conductors was Uri Mayer. In 1981 James Vincent Fusco was appointed as composer in residence and in 1983 Ermanno Florio became the Music Director. He retained this position until 1995 when Michael Reason took over. Daniel Swift was appointed as Music Director and Conductor in 1999 and the Niagara Symphony Orchestra became the orchestr in residence at Brock University. Laura Thomas was appointed as Associate Conductor 1n 2004. Daniel Swift’s resignation in 2008 began a search for a new Music Director. Bradley Thachuck was appointed as Music Director Designate and Principal Conductor in 2010. The orchestra is a fully professional, charitable institution with 52 members.The orchestra has also been led by Victor Feldbrill and Howard Cable. A junior symphony was first formed under Leonard Pearlman in 1960/61, but it wasn’t until 1965 that The St. Catharines Youth Orchestra was founded. The orchestra has consistently been an award winner in music festivals. The musicians range in age from 12 to 18 years. The highlight of the 1973-74 season was the orchestra’s participation in the first Canadian Festival of Youth Orchestras at The Banff School of Fine Arts. The St. Catharines Youth Orchestra has evolved from the St. Catharines School String and Brass Ensembles to a full scale symphony under the direction of conductor Paul van Dongen. In 1974 the Symphony House music program came into existence. It was 1976 when Richard Grymonpre was hired as the principal violinist of the St. Catharines Symphony Orchestra and conductor of the St. Catharines Youth Orchestra. Tak Ng Lai took over the position as conductor in 1978. Laura Thomas is currently the Music Director of The Niagara Youth Orchestra.

Distribuição volumétrica e diâmetro de gotas de pontas de pulverização de energia hidráulica para controle de corda-de-viola

As pontas de pulverização são responsáveis pela formação das gotas, e cada ponta apresenta características próprias relacionadas ao espectro de gotas e perfil de deposição, específicas para determinados alvos. Este trabalho teve o objetivo de caracterizar o diâmetro e a uniformidade das gotas e o perfil de distribuição volumétrica das pontas de pulverização AI 110015 e TTI 110015, bem como seu efeito sobre a mortalidade de corda-de-viola, com herbicida pré-emergente, associado ou não a adjuvantes. Avaliou-se o número de plantas emergidas e os pesos secos da parte aérea e radicular das plantas. Os perfis de distribuição volumétrica para a altura de 40 cm foram avaliados em mesa de deposição. A partir dos perfis de distribuição, simulou-se o padrão de deposição ao longo da barra de pulverização. O espectro do diâmetro de gotas foi determinado em analisador de tamanho de partículas por difração de luz laser . O herbicida diuron + hexazinona foi eficiente no controle em préemergência de corda-de-viola, podendo ser utilizado polimetil siloxano organomodificado ou óleo mineral como adjuvantes, associados às pontas de pulverização AI 110015 ou TTI 110015. O uso de adjuvantes proporcionou aumento no diâmetro mediano volumétrico e redução na porcentagem de gotas com diâmetro inferior a 100 µm. O espaçamento sugerido entre os bicos na barra de pulverização foi de 70 cm para o modelo AI 110015 e 80 cm para o modelo TTI 110015.

Efeito da chuva na eficiência de herbicidas aplicados em pós-emergência sobre corda-de-viola

O objetivo deste trabalho foi avaliar a influência da chuva na eficiência de herbicidas aplicados em pós-emergência em plantas de Ipomoea grandifolia. As plantas de I. grandifolia foram cultivadas em vasos plásticos com capacidade de 2,5 L, em casa de vegetação, com uma planta por vaso. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições, com os tratamentos dispostos em um esquema fatorial 7x8 (sete tratamentos químicos e oito períodos para ocorrência de chuva após a aplicação dos tratamentos). Os tratamentos químicos constaram da aplicação de glyphosate em cinco formulações comerciais (Roundup Original, Roundup WG, Roundup Transorb, Roundup Transorb R e Roundup Ultra) a 1.080 g e.a. ha-1, amônio-glufosinate (Finale) a 400 g i.a. ha-1 e 2,4-D (DMA 806) a 1.000 g e.a. ha-1 e de oito intervalos de tempo para simulação de uma chuva de 15 mm, com duração de cinco minutos: 15', 30', 1h, 2h, 4h, 6h, 8h após a aplicação dos tratamentos e uma testemunha sem chuva, Foram realizadas avaliações visuais de controle das plantas aos 7, 14, 21, 28 e 35 dias após a aplicação e, por ocasião da última avaliação, determinou-se a massa seca das plantas. A ocorrência de chuvas após a aplicação de 2,4-D não alterou a sua eficiência no controle das plantas de I. grandifolia; já os herbicidas amônio-glufosinate e glyphosate, em todas suas formulações testadas, apresentaram redução na eficiência de controle quando da ocorrência de chuvas em até oito horas após a aplicação dos tratamentos.

Oral health-related quality of life and satisfaction before and after treatment with complete dentures in a Dental School in Brazil

Purpose: The aim of this study was to evaluate the impact of treatment with new complete dentures on oral health-related quality of life and satisfaction of edentulous patients attending the Prosthodontic Department in a Dental School in Brazil. Methods: A total of 70 edentulous subjects (37-86 years) treated by undergradute students at the Araçatuba Dental School, University of State of São Paulo, were accessed. A specific questionnaire for edentulous patients (EDENT) based on the Oral Health Impact Profile (OHIP-EDENT) was applied to collect information on patient oral health-related quality of life. Questions related to the personal satisfaction of the edentulous patients with their complete dentures were also included. The patients were accessed before the treatment, and 3 months after receiving the new dentures. Results: After rehabilitation with new complete dentures, all domains of OHIP-EDENT showed significant improvements. There was also a significant improvement in patient satisfaction after placement of new complete dentures. Furthermore, it was possible to observe association between upper denture satisfaction and age. Conclusion: Conventional complete dentures may have a positive impact on oral health-related quality of life and satisfaction of edentulous patients. © 2012 Japan Prosthodontic Society.
