Original Kurzfassung:
The analysis of musical interpretation or expressive performance, an
important research topic in Computer Music, is almost exclusively devoted to
the study of western classical music for the piano. Instruments like the acoustic
guitar and styles like Bossa Nova and Samba have almost never been studied,
despite their harmonic and rhythmic richness. This paper describes some experimental
results obtained with the extraction of rhythmic patterns from the guitar
accompaniment of Bossa Nova songs. The performances were represented
as strings and processed by three different string matchers. Results obtained
showed that parts of a previously acquired catalogue of patterns could be found
in the data set. Surprising results, such as very long patterns, also showed up.
