Quantitative data as the research basis are the records on the sounding frequencies that were measured at the investigation in the Shouwa period. Based on a geometry figure of the bamboo-made shakuhachi in the north warehouse, a physical model is constructed to calculate the sounding frequency from the maximum magnitude of the input admittance at the embouchure hole. The length correction at the embouchure hole is estimated by assuming that this calculated frequency corresponds to the blown frequency measured at the Shouwa investigation. Also, another length correction at the open-hole lattice is derived from the wavelength of the blown sound. These numerical results conducted some discussions on the frequency (fingering) dependence of the length corrections, the octave balance, the cross fingerings and the associated intonation anomaly, the Japanese shakuhachi and the western flute.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","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":"1","bibliographicVolumeNumber":"2011-MUS-89"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:30:56.899629+00:00","id":72682,"links":{}}
