Esta dissertação baseia-se no estudo da introdução da música contemporânea portuguesa de viola d’arco num grupo de alunos de viola d’arco da Casa Pia de Lisboa, através de composições encomendadas a nove compositores portugueses. Incide também na análise das atitudes em relação à música contemporânea portuguesa por parte de professores de viola d’arco portugueses. Procurou-se ampliar o repertório da viola d’arco através da encomenda de obras didáticas, e o repertório expressivo dos alunos envolvidos. Verificou-se que a introdução tardia da música contemporânea no ensino da música e a desatualização dos programas podem condicionar a atitude dos músicos em relação à mesma, sendo importante uma mudança de paradigma. Parecem não existir dificuldades técnicas na abordagem a estas obras por parte dos alunos. Houve também uma aceitação por parte dos professores em introduzir estes conceitos, tendo existido igualmente uma abertura por parte dos compositores contemporâneos envolvidos, em criar obras didáticas para viola d’arco.

One must only glance upon Franz Zeyringer’s 400-page, exhaustive Literatur für Viola to understand the error of the familiar but casual criticism of the paucity of the viola catalogue. Examining Zeyringer’s resource, however, we find a trend: while the viola repertoire contains many pieces (over 14,000 works) and does lay claim to many masterworks (Bartok’s Viola Concerto, Hindemith’s Sonatas, Mozart’s Sinfonia Concertante, etc.), many of the pieces originally written for the instrument are not widely recognized compositions and not often considered outstanding achievements. The violist, much like the double-bassist, bassoonist, and hornist, faces a certain challenge when selecting repertoire for a recital: a lack of large, important works that both fit the instrument and challenge the recitalist. This project will aim to expand recital repertoire for the viola through the development of new transcriptions, using the previously transcribed Fantasy Pieces by Schumann (trans. Leonard Davis) and Sonata No. 2 in E-flat, Op. 120 by Brahms (trans. Brahms) as an inspiration and guide. As a result, the catalogue of viola repertoire will not only be increased but the difference in tone and depth of the instrument may unveil previously unnoticed perspectives on the works. With a primary aim to expand the literature of the viola through the development of new transcriptions, this project will also strive to offer new, previously unnoticed perspectives on preexisting works. Through the changing of the instrumentation, listeners and performers will have the opportunity to explore the character of the compositions in a fresh and possibly illuminating way. Perhaps this project will encourage previously unexplored transcriptions to be realized and performed. While the recital repertoire for the viola boasts many and great works, the original transcriptions of this project attempt to infuse the collection with new and interesting possibilities for both study and performance. This dissertation project is comprised of three recitals featuring works transcribed for viola and, in most cases, newly transcribed by myself. All events took place on the campus of University of Maryland, College Park: Recital #1 on November 9, 2014 in the Gildenhorn Recital Hall of the Clarice Smith Performing Arts Center; Recital #2 on May 9, 2015, in Ulrich Recital Hall; and Recital #3 on November 6, 2015, in the Gildenhorn Recital Hall.

My dissertation presented seven violin concertos in three recital programs. Three of these concertos are acknowledged masterpieces performed in established concert venues throughout the world. They are the concertos of Mozart, Beethoven and Tchaikovsky. The other four are less standard and are composed by Viotti, Kreutzer, Rode and Spohr. These less standard concertos were popular during their time yet they seem not to have stood the test of time. A curriculum devoted exclusively to the standard concertos creates problems for the young violinist. The Mozart violin concertos are often the first standard concertos that the young violin student encounters. They are considered to be the least technically demanding of the standard concertos. The next most advanced standard concertos that the student will usually encounter are Bruch’s G minor concerto, Wieniawski’s D minor concerto and Barber’s concerto. The trouble is that the work on Mozart concertos does not adequately prepare a student for the next most advanced standard concerto. There is a discontinuous leap in the progression of technical difficulty between the Mozart concertos and the next most advanced concertos. Likewise the standard concerto repertoire provides no smooth historical or stylistic progression between the Mozart concertos and the next most advanced concertos. If the young violinist is limited to the standard repertoire then she has no smooth progression either technical, historical or stylistic. I seek to demonstrate that, by adding concertos of Spohr, Viotti, Kreutzer, and Rode to the standard violin curriculum, one could remedy this problem. The first and third recitals were performed in the Gildenhorn Recital Hall and the second recital in the School of Music’s Smith Lecture Hall, both at the University of Maryland. All three recitals can be found in the Digital Repository at the University of Maryland (DRUM).

The enthusiasm towards writing music for the viola that flourished in the early 1900’s thanks to the efforts of a number of twentieth-century violists and composers rapidly spilled over to North and South America. Viola works by American and Canadian composers have already become cornerstones of the viola repertoire worldwide. On the other hand, compositions from other parts of the American continent remain lesser known outside of their country of origin. This is due in part to the less developed publishing and recording industry in these countries which makes it difficult for performers and programmers from other countries to buy or rent performing materials. As a violist born and trained in Venezuela, performing works by important Latin American composers to new audiences is deeply important to me. This dissertation was completed by performing selected works by Canadian, American, Cuban, Mexican, Brazilian, and Venezuelan composers. Composers from these countries have mixed their rich musical traditions with modern compositional techniques, creating original works that have greatly enriched the viola repertoire. This eclectic mixture of styles makes the music from Latin American composers not only very different from that of American and Canadian composers, but also very different from those of their neighboring countries. Through my three dissertation recitals, I intend to share this music with new audiences and inspire other violists to become familiar with this repertoire. The first recital includes compositions by American composers George Rochberg (1918-2015), Elliott Carter (1908-2012), and Alan Shulman (1915-2002) and Canadian composer Elizabeth Raum (b. 1945). The second recital includes works by Cuban composers Cesar Orozco (b. 1980), and Keyla Orozco (b. 1969), Venezuelan composers Aldemaro Romero (1928-2007) and Modesta Bor (1926-1998), and Venezuelan-Uruguayan composer Efrain Oscher (b. 1974). The third recital includes works by Mexican composers Carlos Chavez (1899-1978), José Pablo Moncayo (1912-1958) and Manuel M Ponce (1882-1948), and Brazilian composers Francisco Mignone (1897-1986) and Brenno Blauth (1931-1993). This music represents a bouquet of a distinctive mixture of styles from different parts of the American continent. Recordings of all three recitals can be accessed at the University of Maryland Hornabake Library.

A presente dissertação procura explorar a figura que foi François Broos. Contactando alguns antigos colegas e alunos, procurou-se retratar de forma fidedigna o seu percurso pessoal e profissional, e de que forma a sua vinda para Portugal terá alterado o panorama nacional violetístico, tanto a nível educacional, como artístico. Procurou-se abordar, também, as relações pessoais e profissionais que estabeleceu, tanto no Porto como em Lisboa, com figuras de referência da música em Portugal. Assim, fez-se um breve itinerário pela produção musical para viola no século XX e, de igual forma, uma lista das obras de compositores portugueses para viola e piano ou viola e orquestra, de 1900 a 2000, de forma a verificar se, de facto, houve algum crescimento na produção nacional na música para viola desde que François Broos se instalou em Portugal, e indicar quantas dessas obras lhe terão sido dedicadas. Na segunda parte desta dissertação, e no seguimento do ponto acima mencionado, foram escolhidas duas obras de grande relevância no repertório português para viola, ambas dedicadas ao professor Broos, para serem analisadas do ponto de vista artístico, valorizando os aspetos técnicos da performance, através das respetivas gravações disponíveis.

Edible flowers are being used in culinary preparations to improve the sensorial and nutritional qualities of food, besides improving human health due to the profusion in bioactive compounds [1]. Nevertheless, edible flowers are highly perishable and must be free of insects, which is difficult because they are usually cultivated without using pesticides [2]. Food irradiation is an economically viable technology to extend shelf life of foods, improving their hygiene and quality, while disinfesting insects [3]. The efficiency and safety of radiation processing (using Co-60 or electronaccelerators) have been approved by legal authorities (FDA, USDA, WHO, FAO), as also by the scientific community, based on extensive research [4]. Viola tricolor L. (heartseases), from Violaceae family, is one of the most popular edible flowers. Apart from being used as food, it has also been applied for its medicinal properties, mainly due to their biological activity and phenolic composition [5]. Herein, the phenolic compounds were analyzed by HPLC-DAD-ESI/MS and linear discriminant analysis (LDA) was performed to compare the results from flowers submitted to different irradiation doses and technologies (Co-60 and electron-beam). Quercetin-3-O-(6-O-rhamnosylglucoside)-7-O-rhamnoside (Figure 1) was the most abundant compound, followed by quercetin-3-O-rutinoside and acetyl-quercetin-3-O (6-O-rhamnosylglucoside)-7-O-rhamnoside. In general, irradiated samples (mostly with 1 kGy) showed the highest phenolic compounds content. The LDA outcomes indicated that differences among phenolic compounds effectively discriminate the assayed doses and technologies, defining which variables contributed mostly to that separation. This information might be useful to define which dose and/or technology optimizes the content in a specific phenolic compound. Overall, irradiation did not negatively affect the levels of phenolic compounds, providing the possibility of its application to expand the shelf life of V. tricolor and highlighting new commercial solutions for this functional food.

Acoustically, vehicles are extremely noisy environments and as a consequence audio-only in-car voice recognition systems perform very poorly. Seeing that the visual modality is immune to acoustic noise, using the visual lip information from the driver is seen as a viable strategy in circumventing this problem. However, implementing such an approach requires a system being able to accurately locate and track the driver’s face and facial features in real-time. In this paper we present such an approach using the Viola-Jones algorithm. Using this system, we present our results which show that using the Viola-Jones approach is a suitable method of locating and tracking the driver’s lips despite the visual variability of illumination and head pose.

Acoustically, car cabins are extremely noisy and as a consequence audio-only, in-car voice recognition systems perform poorly. As the visual modality is immune to acoustic noise, using the visual lip information from the driver is seen as a viable strategy in circumventing this problem by using audio visual automatic speech recognition (AVASR). However, implementing AVASR requires a system being able to accurately locate and track the drivers face and lip area in real-time. In this paper we present such an approach using the Viola-Jones algorithm. Using the AVICAR [1] in-car database, we show that the Viola- Jones approach is a suitable method of locating and tracking the driver’s lips despite the visual variability of illumination and head pose for audio-visual speech recognition system.
