Patent number: 6791021Abstract: For both an automatic chord correction and an automatic composition, it is required to correct a part of a series of given chords in order to have a musically natural connection between adjacent chords. A series of chords “a”, “b”, “c”, “d”, “e”, “f” (each letter means one kind of chords) for a music is selected by a user. If two chords “c” and “d” among the series of chords “a”, “b”, “c”, “d”, “e”, “f” are changed into different ones, according to the user's preference or to make them more appropriate to the motif melody, the chord “b” adjacent to the changed “c” is automatically corrected into “b*” so that both chord connections from “a” to “b*” and from “b*” to the changed “c” can be more musically natural.Type: GrantFiled: July 16, 2001Date of Patent: September 14, 2004Assignee: Yamaha CorporationInventor: Eiichiro Aoki

Publication number: 20040112203Abstract: An assistive music playing apparatus is provided for playing a music piece with musically acceptable notes even when the player inputs musically unacceptable notes. The apparatus provides a chord progression pattern, and comprises a note conversion device. A chord progression pattern defines a series of chords, which are presented one after another in time for a music progression. As the player plays music, inputting potentially unacceptable notes, the inputted notes will be converted to musically acceptable notes with reference to the currently presented chord in the chord progression. The note conversion rules are prepared different for a melody note range, a chord note range and a bass note range. Overlap of converted notes are avoided. Depending on the conditions of the player's note input, i.e.Type: ApplicationFiled: September 4, 2003Publication date: June 17, 2004Inventors: Kazuhisa Ueki, Tadahiko Ikeya, Masao Ishibashi, Shinichi Ito, Sachiyo Kubo, Masaki Hara, Tetsuya Takagi
