O contrabaixo orquestral de Villa-Lobos : contextualização, idiomatismo e seleção de excertos /Rosa, Alexandre Silva, 1963- January 2017 (has links)
Orientador: Sonia Ray / Banca: Valerie Albright / Banca: Fausto Borém / Banca: Lutero Rodrigues / Banca: Emerson de Biaggi / Resumo: O contexto e as especificidades do tratamento do contrabaixo nas obras orquestrais de Heitor Villa-Lobos são o objeto principal da investigação aqui apresentada. O estudo tem por objetivo geral discutir a abordagem idiomática empregada pelo compositor na escrita das partituras do contrabaixo na grade orquestral, para, a partir daí, propor a tese de que tais excertos possam ter relevância considerável para o estudo técnico-musical do instrumentista, no que se defende a pertinência de sua adoção por intérpretes, professores e estudantes de contrabaixo. A metodologia de pesquisa inclui extensa revisão de literatura, com visita a autores do século 18 aos dias atuais, seguida de identificação de equivalências idiomáticas no repertório orquestral tradicional, contextualização das influências na escrita para o contrabaixo de Villa-Lobos e concluindo, por fim, com a proposição de uma seleção de excertos para a prática pedagógica. A tese é desenvolvida em três capítulos centrais. O primeiro trata da revisão de literatura sobre estudos de excertos orquestrais para contrabaixo e traça um panorama atual de sua aplicação em instituições locais, pondo em discussão, particularmente, a escassez desses materiais no âmbito da produção orquestral brasileira. O segundo capítulo aborda as influências na escritura das linhas de contrabaixo de Villa-Lobos, com descrição de aspectos idiomáticos na escrita do compositor para o contrabaixo em obras orquestrais, ilustrados com exemplos musicais de sua ... (Resumo completo, clicar acesso eletrônico abaixo) / The context and the specificities of the Villa-Lobos' treatment to the double bass in his orchestral works are the main object of the investigation hereby presented. The main goal is to discuss the idiomatic approach to the double bass on Villa-Lobos' orchestral works as a way to present the thesis that the excerpts of such orchestral works are relevant to the technique musical study of the performer, as well as localizing and indicating its pertinence to double bass performers, professors and students. The methodology chosen was the review of the literature followed by an identification of idiomatic equivalences from the traditional orchestral repertoire, the contextualization of Villa-Lobos' influences on its double bass writing and the selection of excerpts. The thesis is organized in three chapters, besides the introduction, conclusion and appendixes. The first chapter presents the review of the literature on orchestral excerpts for the double bass where today state of the art in Brazilians institutions is presented. The discussion is centered in the lack of material addressed to the studies of Brasilian orchestral works. The second chapter addresses the influences Villa-Lobos received while writing his double bass parts. Here idiomatic aspects of the composers writing for the instrument are described as well as a selection of works that better illustrate such writing and his symphonies, the Choros 10 and the Bachianas 9 are emphasized. The third chapter presents a excerpts selection for the double bass extracted from the works mentioned on chapter two, with emphasis on passages relevant for the technical study of the performer organized by type of idiomatism. The criteria for the selection of excerpts are also presented. At the end of this work it is possible to state that the composer had an elaborated and idiomatic writing for the double bass treating it with respect for its low range nature, ... / Doutor

An Orchestra Audition Handbook for Bass Players.January 2011 (has links)
abstract: The following project is an audition preparation handbook for double bass players. The materials and techniques included are designed for use by advanced collegiate bass players seeking work as freelance or contracted musicians. Subjects ranging from finding an opening, becoming mentally and physically prepared, and developing the skills and experience necessary to be successful will be examined. The most frequently requested audition excerpts are included in this document, carefully extracted from the original orchestra parts and notated with efficient fingerings. Elements of style and performance are discussed. Each of the excerpts is recorded on the enclosed CD, performed by the author as examples to the readers. It is the hope of the author that the study and use of this text will better prepare the readers for entrance into the working world of the music industry. Ideas, processes, and materials that are often neglected in a degree program are examined with the hope that students will be better prepared to audition for, and win orchestral positions. / Dissertation/Thesis / D.M.A. Performance 2011

Comparative ecology and interspecific competition between the sympatric congeners Sebastes caurinus (copper rockfish) and S. maliger (quillback rockfish)Murie, D. J. 29 June 2018 (has links)
Comparative ecology and interspecific competition were
examined between two sympatric congeners, Sebastes caurinus
Richardson 1845 (copper rockfish) and S. maliger (Jordan and
Gilbert 1880) (quillback rockfish) in Saanich Inlet, British
Columbia, Canada, from 1986-1990. Ecological profiles were
constructed through analyses of depth distribution, habitat
and species associations, activities, feeding habits, gut
allometry, growth, and reproduction. Interspecific
competition between copper and quillback rockfish was
examined by experimentally manipulating the densities of one
or the other species on rocky reefs in Saanich Inlet where
they were sympatric.
The Pisces IV submersible was used to survey the
distribution of rockfish in relatively deep-water (21-140 m)
in Saanich Inlet. Copper and quillback rockfish were
sympatric in water depths of 21-65 m. They occurred in
association with one another the majority of the time (>90%)
and their densities were greatest over areas of complex
substrate. Size of copper and quillback rockfish was
positively correlated with increased depth, primarily due to
the absence of small fish in deeper waters. Both species
were observed most frequently perched on open substrate or
hovering in the water column. Copper rockfish were observed
swimming more frequently than quillback rockfish.
Copper and quillback rockfish primarily consumed
demersal crustaceans throughout the year. Copper rockfish
consumed a greater proportion of pelagic fishes than
quillback rockfish, whereas quillback rockfish had a greater
proportion of pelagic crustaceans in their diet. Levins'
(1968) measure of niche breadth of the diet (by mass), as
standardized by Hurlbert (1978), was narrow (0.19-0.20) to
moderate (0.32-0.51) for quillback and copper rockfish
respectively, during spring, summer, and fall. In the
winter it was extremely narrow (0.02) for both species due
to their feeding predominantly on one prey type, juvenile
herring (Clupea harengus) . The Simplified Morisita Index of
niche overlap (Horn 1966) in feeding habits (by mass) was
relatively high (>0.55) throughout the year, and
particularly during the winter (0.99). This high niche
overlap in the winter occurred when large schools of
juvenile herring were available in the environment and were
probably not a limited resource. Extensive niche overlap
between copper and quillback rockfish may therefore indicate
an abundance of a shared resource rather than competition
for the resource.
Copper and quillback rockfish consumed the greatest
quantity of food during the winter when feeding on juvenile
herring, although quillback rockfish consumed significantly
less food mass than copper rockfish in the winter. A
greater proportion of quillback rockfish were collected with
food in their stomachs during the spring and summer, when
the numerically dominant food items were pelagic
crustaceans. The importance of fish prey in the diets of
both copper and quillback rockfish increased with size.
Copper rockfish had a shorter intestine and larger
stomach relative to similar-sized quillback rockfish. This
suggested that the gastrointestinal tract of copper rockfish
was better suited to holding and digesting fish and larger
crustaceans than quillback rockfish, an observation
consistent with differences in their feeding habits.
Copper and quillback rockfish had similar growth
patterns with no readily identifiable species-specific and
sex-specific differences. Both sexes of both species
attained asymptotic lengths of 30-31 cm total length and had
similar growth coefficients (0.141-0.187). Within each sex,
copper rockfish had a smaller increase in mass per unit of
body length than quillback rockfish, indicative of a more
pelagic lifestyle for copper rockfish.
Estimated lengths at first and 100% sexual maturity for
female and male copper and quillback rockfish were similar.
Male copper rockfish were ripe, and potentially inseminated
females, in January and February. Female copper rockfish
were found to be carrying fertilized eggs in April and May,
and gave birth to their young primarily in June. The
reproductive cycle of quillback rockfish preceded that of
copper rockfish by approximately one month, with parturition
for quillback rockfish occurring mainly in May. The
fecundity of copper and quillback rockfish was similar, with
a 30-cm fish giving birth to approximately 90,000 young.
Visceral fat cycles of mature female copper and
quillback rockfish were complementary to their cycles of
gonad maturation and increases in gonad size, indicating
that they use visceral fat stores as a source of energy for
maturation of their eggs and nourishment of their developing
young. Visceral fat cycles of mature males were mainly
coincident with the maturation and size increase of their
gonads, indicating that they did not use visceral fat
reserves in the maturation of their gonads. Male rockfish
secondarily may have used their fat reserves as an energy
source during the period when they were ripe, perhaps for
mating activities. Visceral fat accumulation and
dissipation in immature males and females appeared to be
primarily related to periods of feeding.
Interspecific competition between copper and quillback
rockfish was asymmetrical, seasonal, and transitory, based
on experimental manipulations of the densities of the
congeners in natural populations. Copper rockfish did not
have a competitive effect on quillback rockfish, but
quillback rockfish had a weak competitive effect on copper
rockfish. This effect was apparent only during the fall,
was strongest in the fall immediately following the density
manipulations, and appeared to weaken in the subsequent fall
season. The seasonal competitive effect may have been
caused by copper rockfish moving onto the study reefs (18-31
m depth) from shallower waters (<20 m) during the fall and
winter, creating a short-term 'ecological crunch' in which
food or space resources were limited.
Overall, comparative ecological profiles of copper and
quillback rockfish exhibited a large degree of overlap.
Differences observed between them were small but
consistently indicated that copper rockfish had a more
pelagic lifestyle than quillback rockfish. The otherwise
high degree of similarity between the two congeners,
however, did not translate into sustained interspecific
competition.
Ecological theory purporting a major role for
interspecific competition in structuring fish communities
was therefore not supported by experimental manipulations of
population densities of deep-subtidal, temperate zone
rockfishes. The asymmetrical, seasonal, and transitory
occurrence of weak interspecific competition demonstrated
that competition between these rockfish species is dynamic,
and cannot account for the pattern of species association.
Alternative hypotheses based on the importance of
intraspecific competition, predation, or environmental
variability must therefore be considered. / Graduate

J. F. Daube's "General-Bass in drey Accorden" (1756): A Translation and CommentaryWallace, Barbara Kees 05 1900 (has links)
General-Bass in drey Accorden (1756), the first of Johann Friedrich Daube's theoretical works, is a practical instruction manual in thorough-bass accompaniment. It consists of a sixteen page preface followed by 215 pages of text and musical examples. The twelve chapters begin with a presentation of interval classification and a discussion of consonance and dissonance. Daube then explains a theory of harmony in which all "chords" are derived from three primary chords. These are illustrated with regard to their sequence in harmonic progressions, their resolutions—common and uncommon—, and their use in modulation. Seventy-two pages of musical examples of modulations from all major and minor keys to all other keys are included. Particular attention is given to the fully diminished seventh chord, which is illustrated in all inversions and in numerous modulatory progressions. Daube devotes one chapter to three methods of keyboard accompaniment. The subject matter includes textures, dynamics, proper doubling, the accompaniment of recitatives, full-voiced accompaniment, the use of arpeggiation, trills, running passages, and ornamentation in general.
