Abstract
Desde hace ya varias décadas han surgido numerosos proyectos y estudios que, de diversas maneras, crean puntos de unión entre la música y la computadora. Algunos de estos trabajos toman como entrada de datos las propias partituras musicales, es decir, información simbólica sobre la obra musical a analizar. Mediante el desarrollo de algoritmos específicos, llegan a conclusiones de lo más variadas, como puedan ser clasificaciones en torno a distintos criterios o la obtención de melodías principales, por mencionar algunos ejemplos. Este proyecto entra dentro de este grupo, ya que tiene por objeto realizar una aplicación de análisis de partituras musicales basado en un conocimiento sobre armonía musical. Así, se logra que la computadora llegue a conclusiones inteligentes sobre la obra musical, es decir, resultados similares a aquellos que tendría una persona con conocimientos específicos de armonía musical. Además, tras la realización del análisis, la aplicación genera arreglos de forma automática, es decir, altera la progresión armónica detectada, proponiendo una progresión distinta pero equivalente a la original. -----------------------------------------------------------------------------------------------------------------------------------------------------------------------
For several decades, numerous projects and studies have emerged creating, in various ways, connection points between music and computational science. Some of these works take sheet music as input data, that is to say, symbolic information on the musical work to analyze. Through the implementation of specific algorithms, they can get many different results, such as various classifications or extraction of main melodies just to mention some examples. This project falls within this group, since it carries out an analysis of music scores based on knowledge of musical harmony. Thus, it makes the computer come to conclusions about the musical work, which are close to those from a person with special knowledge of musical harmony. In addition, after the analysis, the computer automatically generates arrangements, in other words, it alters the harmonic progression detected, suggesting a different but equivalent progression to the original one.
