A counterpoint is a subordinated melody which enriches texture of sounds and gives verve to music. A counterpoint sometimes imitates phrases of a main melody and makes up rhythm. Our method composes counterpoints using techniques of imitation and making up. A counterpoint has to avoid interference with a main melody. The method measures the density of notes in each place of main melody and places sounds in a counterpoint depending on the density. By observing the density interference is avoided. In order to guide composition of counterpoints the method takes a harmony or sequence of chords. This paper targets only music in four-four time and in the key of C major.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"18","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"13","bibliographicIssueDates":{"bibliographicIssueDate":"1999-08-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"68(1999-MUS-031)","bibliographicVolumeNumber":"1999"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T05:02:16.746418+00:00","created":"2025-01-18T23:19:44.742552+00:00","id":56290}
