Le Motet et l’Arbre de Jessé. Les pièces à deux voix sur la teneur FLOS FILIUS EJUS dans le codex W2 / Motets and the tree of jesse. Two-part compositions on the tenor FLOS FILIUS EJUS in the manuscript W2

Dobby, Margaret 21 December 2012 (has links)
Les motets du XIIIe siècle chantés sur le répons Stirps Jesse forment l'apogée d'une tradition exégétique, iconographique et musicale plus connue sous le nom d'« arbre de Jessé ». Le répons, attribué à Fulbert de Chartres (mort en 1028), évoque de façon métaphorique les liens entre Marie et son Fils. Il rappelle ainsi un des fondements du dogme chrétien : l'Incarnation charnelle de Dieu par l'intermédiaire de la Vierge. Son utilisation dans les motets n'est donc pas anodine. Le Stirps Jesse, ou plus fréquemment la seconde partie de son verset FLOS FILIUS EJUS, a été repris et ordonné de façon rythmique pour servir à la création d'une polyphonie textuelle et musicale. La voix empruntée ou teneur détermine ainsi la mélodie, la longueur des phrases mélodiques et des vers du double. Pourtant, malgré ces contraintes et les nombreux contrafacta, l'étude démontre l'existence de liens structurels entre texte et musique dans les motets à deux voix sur FLOS FILIUS EJUS conservés dans le manuscrit W2. Les relations entre texte et musique reposent ainsi le plus souvent sur la coïncidence entre la disposition des poèmes et l'organisation des répétitions motiviques (colores), des registres et des rythmes / Thirteenth-Century motets composed on the response Stirps Jesse belong to a great exegetical, iconographical and musical tradition well-known as the « Tree of Jesse ». The response, which is possibly composed by Fulbert of Chartres (d. 1028), express the relationships between Mary and her Son. It calls to mind one of the most important Christian believes as the flesh Embodiment of God thanks to the Virgin which is one of the most important Christian dogmas. The Stirps Jesse, or more often the second part of the verse FLOS FILIUS EJUS, is rhythmically organized in order to create a textual and musical polyphony. The melody, the lengths of musical phrases and of the line of the upper part depend intimately on this quotation or tenor. Even if the tenor is of great influence on the polyphony, this study demonstrates that the textual structure of the upper part corresponds to the musical organization in the two-part motets on FLOS FILIUS EJUS in the manuscript W2. The relationships between poem and melody are built on the close connection between the structural organization of the text and of the melody thanks to the melodic patterns (colores), register and rhythms

No. of bitstreams: 1 Andreza Polizello.pdf: 806973 bytes, checksum: 2f1d51dd54a25808c194bffdd9f6ab2c (MD5) Previous issue date: 2009-05-14 / Secretaria da Educação do Estado de São Paulo / Francis Galton (1822-1911) made important contributions in several fields of science. Among other things, he was the founder of the Biometric School developed by Karl Pearson and Walter Frank Raphael Weldon. The aim of this dissertation is to discuss Galton s ideas on inheritance developed during the period between 1855 (when he published his first works on the subject) and 1889 (when he published the book Natural inheritance), especially focusing his theory of stirps (1872), taking into account the other microscopic models of inheritance proposed in the 19th century. Besides that, it will compare Galton s theory of stirps to Darwin s hypothesis of pangenesis. Moreover, it will try to detect if there were significant changes in Galton s thought concerning the subject during this period. It will also try to elucidate if the low impact received by the theory of stirps was due to a weak foundation. This dissertation contains an introduction and five chapters. Chapter 1 presents some microscopic models of inheritance which were proposed during the 19th century. Chapter 2 discusses Darwin s hypothesis of pangenesis and its test made by Galton. Chapter 3 analyses Galton s theory of stirps. Chapter 4 discusses about the development of Galton s theory of heredity from 1865 to 1892. Chapter 5 provides some final remarks on the subject. This study led to the conclusion that Galton s proposal presented some peculiarities which differentiated it from the other ones of his time such as the experimental test of pangenesis, the performance of several experiments with peas, dogs and the study of genealogies and in addition to this, his concern in giving a statistical treatment to the data. A comparison between his several works showed a continuity of his thoughts on heredity with no significant changes / Francis Galton (1822-1911) trouxe importantes contribuições para diversos campos da ciência. Entre outras coisas, ele foi o fundador da Escola biometricista desenvolvida por Karl Pearson e Walter Frank Raphael Weldon. O objetivo desta dissertação é discutir as idéias de Galton acerca da herança desenvolvidas durante o período compreendido entre 1855 (quando ele publicou seus primeiros trabalhos sobre o assunto) e 1889 (quando ele publicou seu livro Natural inheritance), focalizando especialmente sua teoria das estirpes (1872), levando em conta os outros modelos microscópicos de herança propostos durante o século XIX. Além disso, comparará a teoria das estirpes de Galton com a hipótese da pangênese de Darwin. Procurará detectar se houve mudanças significativas no pensamento de Galton em relação ao assunto tratado durante esse período. Procurará também elucidar se o baixo impacto recebido pela teoria das estirpes se deveu a uma fundamentação fraca. Esta dissertação contém uma introdução e cinco capítulos. O Capítulo 1 apresenta alguns modelos microscópicos de herança que foram propostos durante o século XIX. O Capítulo 2 discute a hipótese da pangênese de Darwin e seu teste feito por Galton. O Capítulo 3 analisa a teoria das estirpes de Galton. O Capítulo 4 comenta sobre o desenvolvimento da teoria da hereditariedade de Galton de 1865 a 1892. O Capítulo 5 apresenta algumas considerações finais sobre o assunto. Este estudo levou à conclusão de que a proposta de Galton apresentou algumas peculiaridades que a diferenciavam das outras propostas de sua época tais como o teste experimental da pangênese, a realização de vários experimentos com ervilhas, cachorros e o estudo de genealogias e, além disso, sua preocupação em dar um tratamento estatístico aos dados. Uma comparação entre seus diversos trabalhos mostrou a existência de uma continuidade em seus pensamentos sobre hereditariedade e a ausência de mudanças significativas. Além disso, parece que o baixo impacto recebido pela teoria das estirpes de Galton não se deveu a uma fundamentação deficiente
