Influence of Musical Similarity on Melodic Segmentation: Representations and Algorithms
In this paper a computational model is presented that extracts patterns from a given melodic surface and, then, following the assumption that the beginning and ending points of 'significant' repeating musical patterns influence the segmentation of a musical surface, the discovered patterns are used as a means to determine probable segmentation points of the melody. ‘Significant’ patterns are de...
متن کاملMelodic segmentation: evaluating the performance of algorithms and musical experts
We review several segmentation algorithms, qualitatively highlighting their strengths and weaknesses. We also provide a detailed quantitative evaluation of Temperley’s Grouper and Cambouropoulos’ Local Boundary Detection Model. In order to benchmark the algorithms’ performance against musicians, we compiled a corpus of different melodic excerpts and collected individual segmentations from 19 mu...
متن کاملEvaluating Melodic Segmentation
We discuss why evaluating melodic segmentation is difficult when solutions are ambiguous and explore the nature of this ambiguity using a corpus of melodies hand-segmented by musicians. For each melody, the musicians identified different, musically coherent solutions, suggesting that ambiguity should be modeled when assessing how “well” an algorithm segments the same melody. We propose a probab...
متن کاملIntegrating Segmentation and Similarity in Melodic Analysis
The recognition of melodic structure depends on both the segmentation into structural units, the melodic motifs, and relations of motifs which are mainly determined by similarity. Existing models and studies of segmentation and motivic similarity cover only certain aspects and do not provide a comprehensive or coherent theory. In this paper an Integrated Segmentation and Similarity Model (ISSM)...
متن کاملThe Influence of Pitch on Melodic Segmentation
Melodic segmentation is an important topic for music information retrieval, because it divides melodies into musically relevant units. Most influential theories on melodic segmentation of the last decades have stressed the role of pitch for melodic segmentation. The general assumption was, that relatively large changes or distances in any musical parameter like pitch, time, dynamics, or melodic...
