Abstract(s)
O presente trabalho trata de aspetos das técnicas estendidas e do piano preparado, com um foco nos compositores Henry Cowell, John Cage, George Crumb e Marisa Rezende. A pouca disponibilidade de referências bibliográficas em língua portuguesa relativas às técnicas estendidas, ao piano preparado e a diversos aspetos ligados a estes temas fomentou este trabalho. Com o objetivo de reunir e sintetizar a informação, aprofundando-a através de exemplos práticos, partiu-se de obras de autores incontornáveis que influenciaram de forma definitiva a adoção destas técnicas na criação de música para piano. Os resultados da pesquisa encontram-se coligidos sob três perspetivas. A perspetiva teórica apresenta reflexões sobre diversos assuntos, como a problemática da tradução do termo extended techniques para português e uma sistematização dos componentes do piano e o seu funcionamento. A perspetiva teórico-prática contém a classificação e exemplos de algumas das técnicas mais comuns, acompanhados por vídeos da sua execução, bem como indicações para a boa prática das técnicas, como cuidados a ter com o instrumento. Por último, a perspetiva mais prática reflete sobre as técnicas usadas nas peças interpretadas no recital final de Projeto Artístico do MIA, nomeadamente as dificuldades encontradas e como foram ultrapassadas.
The present work explores aspects of extended techniques and prepared piano, with major focus on the composers Henry Cowell, John Cage, George Crumb and Marisa Rezende. The low availability of bibliographic references in portuguese language related to the extended techniques, prepared piano and multiple matters of the subject encouraged this research. With the goal of gathering and synthesizing the information, by delving into practial examples, the basis was works by key figures that influenced the use of these techniques in piano composition in a definite way. The research results are here presented under three perspectives. The theoretical perspective reflects about different topics, such as the translation issues of the term extended techniques to Portuguese and a systematization of the piano components and its operation. The theoretical-practical perspective has the classification and examples of some of the most common techniques, together with videos of their execution, as well as indications for their good practise, among which precautions to take with the instrument. By last, the most practical perspective reflects about the techniques used in the works interpreted on the final recital of Projeto Artístico of the Mestrado em Interpretação Artística, namely the encountered difficulties and how they were overcome.
