Approcci computazionali all'analisi musicologica: un caso di studio

The use of Computer Science methodologies applied to Musicology contributed to create a new field of research called Music Information Retrieval (MIR), within the broader area of DSP studies. This interdisciplinary field of research gathers contributions from Informatics, Engineering, Psychology, Musicology and one of its goals is to create new tools to improve our music experience through technology. Currently some business application of MIR is used by multimedia services to automate search operations, detect musical features, transcribe, categorise and suggest music to the listener, synchronise digital processes to external cues. The present study aimed to present some MIR analysis applied on real music compositions. A contemporary piece written by a professional composer was compared to two western classic pieces of music. The results offer new ways to read structural and stylistic differences among the compositions, further they confirm that computational techniques are valued instruments of research and useful tools for the composer aimed to understand a given music language
