Genos is a multidisciplinary Research Group in Music Theory, Composition and Computer Music focused on Computer Music, development and use of Free Software, Musical Analysis and Composition. Genos is registered in CNPq and certified by Federal University of Bahia, Brazil.


Genos is researching about Solo flute repertoire, Music Visualization, Musical Contour Relations Theory, and Brazilian Choros.

Solo flute repertoire

The main goal of this project is to find, classify, and analyze solo flute pieces composed between 1710 and 1810, develop compositional tools based in the data raised in this analysis, compose pieces with these tools, and perform these compositions. The scores will be retrieved from IMSLP, the analysis will be assisted by computational musicology tools and the compositional tools will involve computer-performer interaction.

Music Visualization

Information visualization has been useful in order to increase understanding of complex data in various areas, such as statistics, social studies, as well as music. Data visualization in music can comprehend a broad range of topics, like fugue, form, counterpoint, dodecaphonic series, scales, harmony, and pitch sets, for benefit of either beginners and/or professionals. Nonetheless, more thorough research about the science of visualization have not been made so far, and very few studies came to indicate that visualization can aid students in learning studied topics more effectively.
The main hypothesis of this research is that graphical visualizations can contribute to the understanding of many different musical elements. Our main goals are to develop tools for music visualization, as well as developing methodological approaches for visualization of musical data.
The detailed project, as approved to go on from 2011 to 2014, is available here (in portuguese).

Musical Contour Relations Theory

The research on musical contour relations began in June 2007 as the theme of Marcos da Silva Sampaio Master’s thesis, with the advising of Dr. Pedro Kröger. The approach in that thesis was compositional contour theory operations usage. The main results were the piece Em torno da romã [Around the pomegranate], op. 6 and Goiaba [Guava], a contour processing software. In the second phase of research, initiated in August 2010, the focus of study has been checking for possible inconsistencies in the theories of contours through computational tools MusiContour implemented in software. This new crop is the subject of doctoral Marcos da Silva Sampaio. From September 2010 to voluntary student Francis Strapp joined the team.


Genos members teach classes on Music Theory (harmony, counterpoint, fugue, analysis, set theory), Composition, Computing, and Education in Undergraduate and graduate levels at Federal University of Bahia.
