Marcos Sampaio is a Professor and researcher of Music Theory and Composition at the Federal University of Bahia (UFBA), where he obtained a Ph.D. in Music Composition in 2012. As a researcher, he works in the area of Music Theory, especially Computational Musicology and Musical Contours. He is an editorial board member of the Brazilian Journal of Music and Mathematics (MusMat). He is currently the UFBA Composition and Conducting course coordinator and has been deputy head of the Department of Music at the same university.
He composed works and arrangements for various instrumental formations, presented by groups such as UFBA Orchestra, GIMBA, UFBA Percussion Group, Duo Robatto, and Duo Sacramento. As a bass player, he had performed with the UFBA Percussion Group, the Trama do Macaco Prego, and local artists.
He also has experience in software development. He had coordinated the development team of Disco Azul Produções Artísticas, working in the Beat Percussion Fever and Music Star Blocks software developments. He also developed ContourMetrics, web software for processing musical contours.
Currently, he is researching Haydn’s string quartets according to a quantitative methodology, based on Computational Musicology tools.

In this paper, we present an exploratory study of the pitch registers on the string quartets Opus 17, by Joseph Haydn, according to a quantitative approach. This subject is relevant because the pitch registers studies have revealed noteworthy issues in the Musical Analysis area, the statistical techniques help to detect musical subtleties with a small potential for bias, and because on this corpus, Haydn has established standards for the string quartet genre. The pitch registers study allowed us to identify relevant musical aspects in the repertoire, understand the role of extreme registers in the form segmentation, and observe the prominence of the development and second theme sections, and the feasibility of the quantitative methods. We present a brief theoretical foundation, the methodological framework, the results of the investigation on the quartets' instrument pitches, a discussion about these results, and the conclusions.
