The Grand Sonata in G Major, Op.37, composed by Tchaikovsky, is a powerful large-scale composition and a piece of a symphonic scope. However, the sonata did not receive a desired acclaim in the modern repertoire partially due to an obvious lack of performance instructions in the existing editions, which makes the sonata challenging to perform. Thus, in order to reduce the technical challenges and to encourage more frequent performances of the sonata, this dissertation offers a performer's guide that addresses essential elements of pedal indications, phrasing and detailed dynamics, as well as suggestions on voice balancing, agogics, fingering, and hand redistribution. The guide consists of musical examples that are focused on the most challenging sections of the sonata, and is organized in the subsections according to a technique type proposed to facilitate a performance of the sonata. In addition to the examples on application of individual techniques presented in the main body of the dissertation, alternative and more elaborate versions of the suggestions are proposed in the appendices. The dissertation also provides a history of the sonata, and discusses its concept and symphonic principles. Additionally, the work highlights Tchaikovsky's piano style and describes his views on the art of piano performance. A special attention is also given to two musical references repeatedly embedded into the sonata: the bell-like sonorities and Dies irae melody.

Este trabalho trata do processo de transcrição para violão solo das 12 Danzas Españolas Op. 37 de Enrique Granados, escritas originalmente para piano. Tal processo desenvolveu-se através da observação de versões para violão de outras obras originais para piano, comparações entre os recursos instrumentais específicos desses dois instrumentos e de um levantamento histórico, onde foram analisadas as principais problemáticas de adaptação dos elementos musicais e estéticos da obra original em um novo meio. A fim de contextualizar esse trabalho no panorama da transcrição, visitamos a história de Granados, analisando os aspectos gerais de suas Danzas Españolas, bem como discutimos a conceituação da scordatura para, a partir daí, empregar o método de pesquisa de diferentes possibilidades de afinação na busca de viabilizar a transcrição da obra em questão, sem perder de vista, durante esse processo, a ideia original do compositor. Através dos resultados alcançados, da maneira como compreendemos os métodos empregados, constatamos um amplo campo de possibilidades a serem pesquisadas e novas soluções de adaptação e scordature a serem empregadas, estabelecendo a prática da transcrição como um procedimento válido artisticamente, desde que devidamente contextualizado. / This work deals with the process of transcription for guitar solo of the 12 Danzas Españolas Op. 37 of Enrique Granados, written originally for piano. This process was developed through the observation of guitar versions of other original works for piano, comparisons between the specific instrumental resources of these two instruments and a historical survey, where the main problems of adaptation of the musical and aesthetic elements of the original work were analyzed in a new medium. In order to contextualize this work in the transcription panorama, we visit the history of Granados, analyzing the general aspects of its Danzas Españolas, as well as discussing the conception of the scordatura to, from there, to use the research method of different tuning possibilities in the seeking to make feasible the satisfactory assimilation of the work in question, without losing sight of, during this process, the original idea of the composer. Through the results obtained, as understood by the methods employed, we find a wide field of possibilities to be researched and new solutions of adaptation and scordature to be used, establishing the practice of transcription as an artfully valid procedure, provided that it is properly contextualized.

The purpose of this thesis is to investigate the use of isorhythm in two of Arnold Schoenburg's chamber works, the Third and Fourth String Quartets. The study of rhythm in twelve-note music has been generally relegated to a position less prominent than that held by the study of any of the other important aspects of the style. This condition is due probably to the fact that rhythm underwent less change with the advent of the twelve-note school of composition than melody, counterpoint, or harmony experienced. However, Rufer states that "rhythm has a special formal function in Schoenberg's twelve-note music, in addition to its motivic function and to that of creating subdivisions.

This thesis uses two different musical analytical systems, one of Heinrich Schenker and one of Paul Hindemith, to analyze tonality within "Die Gurre Lieder" and "Fourth String Quartet" by Arnold Schoenberg.
