The focus is on pop\/rock guitar and bass guitar melodies with the aim of eventual extensions to other instruments and musical styles. It is demonstrated here how learning musical style from segmented audio data can be formulated as an unsupervised learning problem to generate a symbolic representation. A melody is first segmented into a sequence of notes using onset detection and pitch estimation. A set of hierarchical, coarse-to-fine symbolic representations of the melody is generated by clustering pitch values at multiple similarity thresholds. The variance ratio criterion is then used to select the appropriate clustering levels in the hierarchy. Note onsets are aligned with beats, considering the estimated meter of the melody, to create a sequence of symbols that represent the rhythm in terms of onsets\/rests and the metrical locations of their occurrence. A joint representation based on the cross-product of the pitch cluster indices and metrical locations is used to train the prediction model, a variable-length Markov chain. The melodies generated by the model were evaluated through a questionnaire by a group of experts, and received an overall positive response. <\/jats:p>","DOI":"10.1162\/comj_a_00184","type":"journal-article","created":{"date-parts":[[2013,9,26]],"date-time":"2013-09-26T18:51:12Z","timestamp":1380221472000},"page":"68-81","source":"Crossref","is-referenced-by-count":3,"title":["Automatic Phrase Continuation from Guitar and Bass Guitar Melodies"],"prefix":"10.1162","volume":"37","author":[{"given":"Srikanth","family":"Cherla","sequence":"first","affiliation":[{"name":"Music Informatics Research Group, A309 (College Building), City University London, 10 Northampton Square, London EC1V 0HB, United Kingdom."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hendrik","family":"Purwins","sequence":"additional","affiliation":[{"name":"Neurotechnology Group, Berlin Institute of Technology, Fakult\u00e4t IV, MAR 4\u20133, Marchstra\u00dfe 23, 10587 Berlin, Germany; Sound and Music Computing Group, Department of Architecture, Design and Media Technology, Aalborg University, Copenhagen, Denmark."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Marchini","sequence":"additional","affiliation":[{"name":"Music Technology Group, Communication Campus-Poblenou, Universitat Pompeu Fabra, Roc Boronat, 138 08018 Barcelona, Spain."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","reference":[{"key":"p_2","doi-asserted-by":"publisher","DOI":"10.2307\/1578334"},{"key":"p_3","first-page":"496","author":"Assayag G.","year":"1999","journal-title":"Proceedings of the International Computer Music Conference"},{"key":"p_4","doi-asserted-by":"publisher","DOI":"10.1109\/TSA.2005.851998"},{"key":"p_5","first-page":"131","author":"Biles J.","year":"1994","journal-title":"Proceedings of the International Computer Music Conference"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1214\/aos\/1018031204"},{"key":"p_8","doi-asserted-by":"publisher","DOI":"10.1080\/03610927408827101"},{"key":"p_10","first-page":"30","author":"Conklin D.","year":"2003","journal-title":"Proceedings of the AISB Symposium on Artificial Intelligence and Creativity in the Arts and Sciences"},{"key":"p_11","doi-asserted-by":"publisher","DOI":"10.1080\/09298219508570672"},{"key":"p_13","doi-asserted-by":"publisher","DOI":"10.1121\/1.1458024"},{"key":"p_14","first-page":"224","author":"Dubnov S.","year":"2007","journal-title":"Proceedings of the International Computer Music Conference"},{"key":"p_15","first-page":"90","author":"Duxbury C.","year":"2003","journal-title":"Proceedings of the Conference on Digital Audio Effects"},{"key":"p_16","doi-asserted-by":"publisher","DOI":"10.1080\/01621459.1967.10500923"},{"key":"p_18","doi-asserted-by":"publisher","DOI":"10.1145\/331499.331504"},{"key":"p_20","first-page":"477","author":"Marchini M.","year":"2010","journal-title":"Proceedings of the Sound and Music Computing Conference"},{"key":"p_21","doi-asserted-by":"publisher","DOI":"10.1121\/1.2935489"},{"key":"p_22","doi-asserted-by":"publisher","DOI":"10.1007\/BF02294245"},{"key":"p_23","doi-asserted-by":"publisher","DOI":"10.1080\/09540099408915726"},{"key":"p_24","doi-asserted-by":"publisher","DOI":"10.1076\/jnmr.32.3.333.16861"},{"key":"p_26","doi-asserted-by":"publisher","DOI":"10.1007\/BF00114008"},{"key":"p_27","doi-asserted-by":"publisher","DOI":"10.1016\/0010-0277(95)00665-6"}],"container-title":["Computer Music Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mitpressjournals.org\/doi\/pdf\/10.1162\/COMJ_a_00184","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,3,12]],"date-time":"2021-03-12T21:33:34Z","timestamp":1615584814000},"score":1,"resource":{"primary":{"URL":"https:\/\/direct.mit.edu\/comj\/article\/37\/3\/68-81\/94434"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,9]]},"references-count":20,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2013,9]]}},"alternative-id":["10.1162\/COMJ_a_00184"],"URL":"https:\/\/doi.org\/10.1162\/comj_a_00184","relation":{},"ISSN":["0148-9267","1531-5169"],"issn-type":[{"value":"0148-9267","type":"print"},{"value":"1531-5169","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,9]]}}}
