Abstract: Through an operation by a user, a setting is made, for each partial musical section in a music piece, as to whether or not music piece data should be generated. In accordance with the setting, a discrimination is made between a data-generating musical section where music piece data should be generated and a non-data-generating musical section where music piece data should not be generated. In automatically composing a music piece on the basis of given musical conditions, music piece data based on the given musical conditions is generated only for the data-generating musical section, and generation of music piece data based on the given musical conditions is inhibited for the non-data-generating musical section. With this arrangement, music piece data for each partial musical section in an already-composed or existing music piece can be re-created with greatly increased ease.

Abstract: Given melody notes are classified into particular notes and other notes than the particular notes in accordance with a predetermined criterion. Additional notes are decided with respect to the classified particular notes and the other notes in accordance with different criteria set for the classified particular notes and the other notes, to generate an auxiliary melody with the additional notes. For example, for each of the particular notes, an additional note is decided which has a predetermined musical interval from the particular note, so as to generate a plurality of additional notes with more emphasis on good sounding with the particular notes. For each of the other melody notes than the particular notes, an additional note is decided which has a musical interval determined on the basis of a flow of at least one of the main melody and the auxiliary melody, so as to generate additional notes with more emphasis on note-to-note connections of a generated auxiliary melody.

Abstract: From a given melody motif is extracted a rhythm pattern consisting of a series of rhythmic alignment of notes without a pitch representing the time positions of the notes constituting the melody. Also extracted from the given melody motif are the pitches of the skeleton notes which are notes having primary importance in the rhythm pattern in view of rhythm beats such as the strong beat notes. A rhythm pattern which is similar to the motif rhythm pattern is provided, for example, by searching through a data base including various rhythm patterns. The skeleton notes in the searched similar rhythm pattern are given the pitches identified by the extracted pitches, respectively at corresponding time positions. The non-skeleton notes are given pitches using, for example, passing notes, unison, appoggiatura, changing notes and after notes according to the musical rules relative to the pitch given skeleton notes. Thus, a length of melody similar to the melody motif is obtained.

Abstract: A rhythm pattern is provided to be subjected to forward syncopation processing. The time position of an un-syncopated note in the rhythm pattern is shifted forward to render advanced beating of the note to make a forward-syncopated rhythm pattern. The notes in the modified rhythm pattern are given respective note pitches to establish a melody, wherein the skeleton notes in the rhythm pattern are given skeleton pitches, and the non-skeleton notes in the rhythm pattern are given non-skeleton pitches. The advanced beating of a note makes a skeleton note which plays an important role in syncopation.

Abstract: Automatic composition apparatus and method is able to automatically compose a piece of music having a melody that is favorable in a musical sense, namely, a melody that satisfies musical requirements. A storage medium stores a program executed for automatically composing a piece of music having such a melody as described above. After melody pitches are generated under moderate first melody generation conditions, the generated melody pitches are evaluated in terms of more strict second melody generation conditions. With regard to a certain pitch, therefore, it can be determined whether the pitch satisfies musical requirements in view of not only the previous pitch but also the next pitch, thus making it possible to compose a piece of music that as a whole is favorable in a musical sense.
