Subject:Automated boundary strength detection in a music score
Time:01:35 pm
Automated music analysis is a multidisciplinary ongoing research topic. It addresses at a broad range of scientific areas, including cognitive sciences, psychology, applied AI and, of course, musicology. An effective segmentation of a music piece is essential for extracting information from the score. Current AI development show a reproduction of human mental process for music analysis is too sophisticated for a machine, therefore a rule based model is preferred. Usually this kind of models are based on variational calculations. Using the Matlab MIDI toolbox, developed at University of Jyvaskyla, a rule based segmentation algorithm based on the work of Cambouropoulos E. (A Formal Theory for the Discovery of Local Boundaries in a Melodic Surface, Proceedings of the III Journees d' Informatique Musicale, Caen, France, 1996) and examples from baroque, classical and romantic piano repertoire are proposed. The algorithm use a MIDI notation to extract pitch, rest duration and note duration. By using three arbitrary coefficients it is possible to built a vector (boundary strength)corresponding to the energy level of a score, in analogy with the potential energy, defined as difference between an arbitrary level of potential function in a conservative field. The following equations show the concept of the boundary strength vector.

Some examples... )

Further development include the analysis of beats and basic harmonic analysis (bass in root position) and an integration with a recently developed algorithm that find the match level between notation and performance, based on the work of Palmer & van de Sande, 1993. This integration, with the help of well trained performers, will lead to a better understanding of music style, and to a wide range of applications, including an improved style-based automated composition, automated error detection in scores and reconstruction of incomplete scores.

Time:12:29 am
5 giorni a Milano con amore. Lontano dagli impegni e nella mia nuova stanza. Giorni di socialità e di nuove belle conoscenze, e di incontri con i vecchi amici. Giorni di spettacoli vari, tra cui la visita all'Hangar Bicocca (vedi foto)


le grandi torri di Anselm Kiefer - "I Sette Palazzi Celesti"


i muri di luce di Anthony McCall - "Breath" 


Tutto sempre insieme alla mia gatta. Ora sono tornato, solo, alla ville de Lyon.


questa è una cartolina che mio padre ha trovato tra le nostre vecchie cartoline, ritrae Place de la Republique a Lyon nel 1902.
