Study done for the exam of the course "Análisis 4" ("Analysis 4"), lectured by prof. Marcelo Rilla at the Escuela Universitaria de Música (University School of Music) of the Universidad de la República (University of the Republic), in Montevideo, Uruguay. It is recommended to read the written analysis of each song while also reading the score in C included at the end of each analysis (and, as these scores omit indications included in the original score, it might be convenient to read the original score as well).
