Aproximación a la complejidad de la interpretación de música contemporánea colombiana para violonchelo solo y piano acompañante del siglo xx

Abstract

The purpose of this work is to develop a framework for the musical interpretation of five contemporary works by 20th-century Colombian composers: Bicinium VI and Sonata for Cello and Piano Op. 186 by Blas Emilio Atehortúa, Sonata for Solo Cello by Roberto Pineda Duque, Mesure by Jacqueline Nova, and Trópico de Capricornio by Guillermo Rendón. Due to the technical and expressive complexity these works present for the cello, the author analyzes the context of contemporary music, its interpretation, and fundamental aspects such as fluency, intonation, and instrument technique. The study includes a review of the repertoire, characteristics of contemporary music—such as atonality, the use of new textures, and non-linear temporal structures—and a methodology based on fidelity to the composer's ideas, the interpreter's experience, and the contemporary musical environment. Musical trends such as dodecaphonism, serialism, and aleatoric music are also examined, with an emphasis on their development in Colombia. The musical analysis of each piece includes the composer's context, stylistic characteristics, formal structure, technical demands, and musical elements such as rhythm, melody, harmony, dynamics, and phrasing.
