This motion (called the Helmholtz motion) was first discovered by Helmholtz. We were carried out numerical simulations of the bowed string vibration in the starting transients. The wave motion was analyzed not only at the bowing position but over the whole string. As the result, it suggested that (1) the acceleration of the bowing is needed to create the Helmholtz motion and (2) loss at the nut is important to stabilize the bowed string motion. Also, the bowed string motion is such a simple triangle as Helmholtz suggested, and a small corner is likely to be formed at the bowing position.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告 音楽情報科学（MUS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-02-04","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2011-MUS-89"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:30:57.045350+00:00","id":72685,"links":{}}
