Research
Visgraf's research in music covers sound morphing techniques and methods for visualization of musical information, detection of chords using video, and systems of music improvisation on multi-touch devices.
Marcelo Cicconet Thesis
The Guitar as a Human-Computer Interface (2010)
This work explores the visual interface of the guitar. From the analysis point of view, the use of a video camera for human-computer interaction in the context of a user playing guitar is studied. From the point of view of synthesis, visual properties of the guitar fretboard are taken into account in the development of bi-dimensional interfaces for music performance, improvisation, and automatic composition.
Sergio Krakowski Thesis
Rhythm-Controlled Automata Applied to Musical Improvisation (2009)
The main contribution of this thesis is to propose a Framework to generate Rhythmically- Controlled Multi-Mode Audio-Based Interactive Systems used create variable-form im- provised pieces in real musical performance contexts.
Visual Language for Music Understanding
This webpage accompanies the paper submitted to Journal of Visualization. The paper describes a simple visual language which improves the interpretation of chamber music compositions. Illustrated videos generated with the proposed visual language are available.
Algorithmic Composition based on CNA
This paper proposes an algorithm that composes music based on complex network analysis. In the computer, the music of a composer is represented within a network, then, such knowledge is re-utilized to compose new music. In addition, it is shown that the node degrees distribution, from different musical networks, follows a power-law distribution which means scale-free networks.
