Study done to correct homework of students of the course "Armonía 4" ("Harmony 4"), as part of my work as a Harmony and Counterpoint student teaching assistant at the Escuela Universitaria de Música (University School of Music) of the Universidad de la República (University of the Republic), in Montevideo, Uruguay (chair: Alejandro Barbot). It is recommended to read the written analysis while also reading the analyzed score, included at the final pages of this document (and, as the analyzed score omits indications included in the original score, it might be convenient to read the original score as well).
