Focusing on a slight and abrupt change in bore radius, the resulting differences in the response of the air column were examined. Two kinds of physical models were assumed based on the trumpet bore shape: One has a discontinuity in radius at the connection between the mouthpiece and the instrument body; the other has no such a discontinuity. Simulations on the self-oscillation were performed in both steady-state and attack transient conditions after deducing the reflection functions from the assumed bore shapes. The effect of the bore discontinuity was not detected in the steady-state oscillation, but appreciably appeared in the attack transients.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"48","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"43","bibliographicIssueDates":{"bibliographicIssueDate":"2003-02-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"16(2002-MUS-049)","bibliographicVolumeNumber":"2003"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:19:34.805284+00:00","id":56074,"links":{}}
