Vassilakis D, Anagnostopoulou C, Georgaki A. Jazz Mapping: an analytical and computational approach to Jazz improvisation. In: SMC. Malaga University; 2019.Abstract
“Jazz mapping" is a multi-layered analytical approach to jazz improvisation. It is based on hierarchical segmentation and categorization of segments, or constituents, according to their function in the overall improvisation. The approach aims at identifying higher-level semantics oftranscribed and recorded jazz solos. At these initial stages, analytical decisions are rather exploratory and rely on the input of one of the authors and experienced jazz performer. We apply the method to two well-known solos, by Sonny Rollins and Charlie Parker, and discuss how improvisations resemble story-telling, employing a broad range of structural, expressive and technical tools, usually associated with linguistic production, experience, and meaning. We elucidate the implicit choices of experienced jazz improvisers, who have developed a strong command over the language and can communicate expressive intent, elicit emotional responses, and unfoldmusical “stories” that are memorable and enjoyable tofellow musicians and listeners. We also comment on potentialartificial intelligence applications of this work to music research and performance.
Petras G, Tsangarakis P, Georgaki A. Extended Drama Prosodic Tools: Design and Aesthetics. In: International Journal of Music Science, Technology and Art ( ; 2019.Abstract
In this article we present an interactive toolkit for the extended vocal  performance of Attic tragic poetry in drama related to its prosodic aspects. We focus on the development of modules for the phonological articulation of the ancient text based on archeomusicological readings (related to music and language) in order to add aesthetic values to the modern performance of ancient Greek drama. These tools are based on prosodic elements (melodic, rhythmic) of the ancient text and are used to: a) detect the dynamic of the articulation, accent, pronunciation as well as the tonality/pitch of the actor’s voice (recited or sung), b) track the movements and gestures of the performer and c) combine the data which is collected by the above mentioned processes (a and b) to trigger interactive sound and speech processing during the performance in order to reintroduce the prosodic aspects of voice in ancient drama.
