Method and device for automatic music composition employing music template information

Abstract

For each section forming a music piece, music template information is supplied which includes at least information indicative of a pitch variation tendency in the section. A plurality of already-composed music pieces are preferably analyzed to store a plurality of pieces of such music template information so that any users can select from the stored pieces of music template information. For a music piece to be composed, the user enters information indicative of a tendency relating to the number of notes, such as syllable information of desired words or scat words, in each section of the music piece. On the basis of one of the pieces of music template information supplied and the user-entered information indicative of the number-of-notes tendency (syllable information), the length and pitch of notes in each section can be determined, which permits automatic generation of music piece data. If the music template information is used with no modification, an automatically composed music piece will considerably resemble its original music piece. The user can freely modify the music template information to be used, so that a music piece different from its corresponding original music piece can be created with the user's intention reflected thereon. The music template information can be easily modified by any users having poor knowledge of composition, and the present composing technique can be easily used by everyone.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a method and device for automatically composing a piece of music in accordance with various musical conditions.[0002]With a widespread use of personal computers, everyone has now come to be able to freely enjoy various types of music through the “computer music” technique, which uses a computer to play a musical instrument, compose a piece of music (music piece), arrange a composed music piece and synthesize to a tone color. Particularly, in the field of music composition using a computer, even people without expert knowledge of music can compose easily by just entering and setting various musical conditions as directed by the computer. In addition, automatic music composing devices have recently been proposed which analyze characteristics of a melody to an original music piece by classifying the melody into harmonic and non-harmonic tones and further classifying the non-harmonic tones. The proposed automatic music co...

Benefits of technology

[0023]If performance data representing a music piece are for example MIDI data, the performance data input section supplies the performance data along with data indicative of phrase divisions, measure lines, etc. The characteristic extraction section analyzes the performance data for each phrase and measure line in order to extract the musical characteristics, such as pitch and rhythm patterns, for each phrase and measure. Therefore, the characteristic extraction section extracts a plurality of the musical characteristics for a single music piece. The storage sect

Problems solved by technology

This technique, however, can only compose a music piece with a limited note combination (positions of individual positions within a measure) because the note combination is fixedly contained in the pattern.

However, this publication fails to describe in detail a manner in which notes are allocated to the formed melody outline and only discloses that a music piece is created by entering musical rules.

Because the known automatic composing techniques in the filed of computer mu
