{"pk":27663,"title":"Effects of Auditory-Feedback Delays and Musical Roles on Coordinated TimingAsymmetries in Piano Duet Performance","subtitle":null,"abstract":"Recent research in human behavioral dynamics has demonstrated that co-actors often successfully achieve jointgoals by adopting functionally asymmetric patterns of behavior. To better understand the evolution of such patterns in anaturalistic musical context, the current study examined how auditory-feedback delays and individual musical roles affectcollective temporal stability and relative adaptability during duet performance. The delays between pianists were short (10-40 ms), bidirectional, and remained constant during a single trial, simulating those typical in internet-mediated performance.Preliminary results show increasingly reduced collective stability for longer delays along with a distinct pattern of asynchroniesacross the points where temporal synchrony would be expected, in which individuals exhibited consistent alternation betweenplaying before or after their co-performer. Furthermore, asynchronies became greater when the two musical parts were lesssimilar. Thus, emerging coordinative dynamics appear to be shaped both by asymmetries in co-performers’ assigned roles andexternal constraints on shared information.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Posters: Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/8f77d7zv","frozenauthors":[{"first_name":"Auriel","middle_name":"","last_name":"Washburn","name_suffix":"","institution":"Stanford University","department":""},{"first_name":"Matthew","middle_name":"","last_name":"Wright","name_suffix":"","institution":"Stanford University","department":""},{"first_name":"Takako","middle_name":"","last_name":"Fujioka","name_suffix":"","institution":"Stanford University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T10:00:00-08:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27663/galley/17299/download/"}]}
