Indetermination in Expressão Anímica by Eunice Katunda: an interpretative overview

The main objective of this paper is to verify indetermination elements used by Brazilian composer Eunice Katunda in her piano piece Expressão Anímica (1979), as well as the compositional procedures adopted by the composer. Departing from the musical parameters – time, duration, pitch and effect - the use of indetermination is analized, as well as all types of notation used in the piece – such as exact, aproximative, indicative notation and music grafics. The methodology consisted of reviewing related literature and music notation studies. Finally, a possible performance is proposed.
