A computational exploration of melodic patterns in Arab-Andalusian music. Journal of Mathematics and Music. 2021;15(2):168-80. DOI: 10.1080/17459737.2021.19170101745-9737http://hdl.handle.net/10230/47632Here we present a computational approach to identifying melodic patterns in a dataset of 145 MusicXML scores with the aim of contributing to centonization theory in the Moroccan tradition of Arab-Andalusian Music – a theory in development by expert performer and researcher of this tradition, Amin Chaachoo. Central to his work is the definition of a set of characteristic patterns, or centos, for each ṭab‘, or melodic mode. We apply three methods: TF-IDF, Maximally General Distinctive Patterns (MGDP) and the Structure Induction Algorithm (SIA) to identify characteristic patterns at the level of ṭab‘. A substantial number of the centos proposed by Chaachoo are identified and new melodic patterns are retrieved. A discussion with Chaachoo about the obtained results promoted the elicitation of other categories of recurrent patterns in the tradition different from the centos, contributing to a deeper musicological knowledge of the tradition.application/pdfeng© This is an Accepted Manuscript of an article published by Taylor & Francis in JOURNAL OF MATHEMATICS AND MUSIC on 12-05-2021, available online: http://www.tandfonline.com/10.1080/17459737.2021.1917010info:eu-repo/semantics/articlehttp://dx.doi.org/10.1080/17459737.2021.1917010Computational musicologyPattern discoveryCentonizationExploratoryArab-Andalusianinfo:eu-repo/semantics/openAccess
