Abstract: Performance information of one or more accompaniment parts is extracted from original performance information. Arranged accompaniment performance information is created using, in accordance with a predetermined arranging condition, only any one or more of pitch names included in the extracted accompaniment performance information. The predetermined arranging condition comprises instructing that any of chord component notes be thinned out in an identified chord progression, and arranged accompaniment performance information is created by thinning out an accompaniment note of a pitch name corresponding to the chord component note having been instructed to be thinned out. Another predetermined arranging condition comprises setting a ratio between chords and arpeggios in one or more measures, and a combination of chords and arpeggios in the extracted accompaniment part performance information is changed so that a ratio between chords and arpeggios in one or more measures in the extracted accompaniment performance information assumes the set ratio.

Abstract: An accompaniment sound generating device includes a specifier, an accompaniment sound generator, and an accompaniment sound outputter. The specifier specifies a plurality of musical performance parts for which accompaniment sounds are generated based on an input musical performance sound. The accompaniment sound generator generates the accompaniment sounds that belong to the plurality of specified musical performance parts for each musical performance sound. The accompaniment sound outputter outputs the accompaniment sounds generated for the plurality of musical performance parts with timing for generating the accompaniment sounds aligned with timing for generating musical performance sounds.

Abstract: Arranged accompaniment data are created by: acquiring original performance information; extracting, from the acquired original performance information, one or more accent positions in a music piece represented by the acquired original performance information; acquiring existing accompaniment pattern data; and adjusting time positions of one or more accompaniment notes, which are to be generated on the basis of the acquired accompaniment pattern data, so as to coincide with the extracted one or more accent positions. In this way, it is possible to create accompaniment data matching accent positions (rhythmic elements) of the music piece represented by the original performance information and thereby automatically make a musical arrangement with respective characteristics of the existing accompaniment pattern data and original performance information remaining therein.

Abstract: Individual chords and bar lines are extracted from an acquired chord chart described in text. Further, musical time information indicative of a musical time of music data to be generated is acquired, chord progression information is generated by allocating in-bar relative time positions to the extracted individual chords in accordance with the musical time indicated by the acquired musical time information and the extracted bar lines. A chord chart display can be provided based on the generated chord progression information. Further, accompaniment pattern data is acquired, and automatic accompaniment data can be generated by controlling the acquired accompaniment pattern data in accordance with the generated chord progression information.

Abstract: Performance information of main music is sequentially acquired, and an accent position of the music is determined. An automatic accompaniment is progressed based on accompaniment pattern data. Upon determination that the current time point coincides with the accent position, an accompaniment event whose tone generation timing arrives within a predetermined time range following the current time point is extracted from the accompaniment pattern data, the tone generation timing of the extracted accompaniment event is shifted to the current time point, and then, accompaniment data is created based on the accompaniment event having the tone generation timing thus shifted. If there is no accompaniment event whose tone generation timing arrives at the current time point or within the predetermined time range following the current time point, automatic accompaniment data with the current time point set as its tone generation timing is additionally created.
