ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an automatic music composing apparatus and automatic music composing program that create musical compositions in synchronization with images.
2. Description of the Related Art
Conventionally, a background music (referred to below as BGM) generator is known that generates BGM in synchronization with images so that the BGM matches the mood of the images. In this BGM generator, fragment data (including accompaniment data and data for generating a melody) of a plurality of songs is prerecorded on a database. When a music genre or rhythm that matches the mood of the images and the length (e.g., the length of time or number of frames of the images) of the images to which a user wishes to attach the BGM is specified by an input from the user, fragment data of music that matches the specification by the user is read from the database. The read fragment data of this music is joined together in the correct manner to generate BGM that matches the length of the images.
However, since music is thus generated by the conventional BGM generator by joining together fragments of data of music, when a single musical composition is generated by joining together fragment data, the music has little sense of continuity.
Moreover, in spite of groups of data for generating a plurality of melodies being registered in the database for one set of accompaniment data, only a few musical compositions can be generated using the same accompaniment source. If fragment data prepared for another accompaniment is used, then the number of musical compositions that can be generated using the same accompaniment source does increase somewhat, however, the accompaniment and the melody conflict with each other in many cases so that, hitherto, the music has only seemed partially completed.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an automatic music composing apparatus and an automatic music composing program capable of generating music with a high degree of completion in synchronization with images and in a time that matches the length of images.
To attain the above object, in a first aspect of the present invention, there is provided an automatic music composing apparatus that automatically creates musical compositions to be reproduced as a background for images, comprising a bar number calculating device that calculates a number of bars of a musical composition that corresponds to a time period required by each of sections of images, a bar number-corresponding data acquiring device that acquires bar number-corresponding data necessary to generate the musical composition and corresponding to the calculated number of bars, a musical composition generating device that generates the musical composition based on the acquired bar number-corresponding data, and an output device that outputs the generated musical composition according to each of the sections of the images.
Preferably, the automatic music composing apparatus according to the first aspect comprises a musical composition length adjusting device that adjusts a length of the musical composition such that the generated musical composition has a length matching a time period required by a corresponding one of the sections of the images, and wherein the output device outputs the musical composition having the length thereof adjusted, according to each of the sections of the images.
Also preferably, the bar number-corresponding data acquiring device acquires the bar number-corresponding data in units of a predetermined number of bars, and wherein the apparatus comprises a deleting device that deletes a portion of the bar number-corresponding data such that the acquired bar number-corresponding data corresponds to a number of bars that is greater than and is closest to a number of bars required for generating the musical composition.
To attain the above object, in the first aspect of the present invention, there is also provided an automatic music composing program that is executed by a computer, comprising a bar number calculating module for calculating a number of bars of a musical composition that corresponds to a time period required by each of sections of images, a bar number-corresponding data acquiring module for acquiring bar number-corresponding data necessary to generate the musical composition and corresponding to the calculated number of bars, a musical composition generating module for generating the musical composition based on the acquired bar number-corresponding data, and an output module for outputting the generated musical composition according to each of the sections of the images.
To attain the above object, in a second aspect of the present invention, there is provided an automatic music composing apparatus that automatically creates musical compositions to be reproduced as a background for images, comprising a bar number calculating device that calculates a number of bars of a musical composition that corresponds to a time period required by each of sections of images, a bar number-corresponding data acquiring device that acquires bar number-corresponding data necessary to generate the musical composition and corresponding to the calculated number of bars in units of a predetermined number of bars, the bar number-corresponding data acquiring device acquiring the bar number-corresponding data that corresponds to a number of bars that is greater than and is closest to a number of bars required for generating the musical composition, a musical composition generating device that generates the musical composition based on the acquired bar number-corresponding data, a musical composition length adjusting device that adjusts a length of the musical composition such that has a length matching a time period required by a corresponding one of the sections of the images, and an output device that outputs the musical composition having the length thereof adjusted, according to each of the sections of the images.
Preferably, in the automatic music composing apparatus according to the second aspect, the musical composition length adjusting device comprises a bar number deleting device that deletes a portion of the number of bars of the musical composition generated by the musical composition generating device, a tempo adjusting device that adjusts a tempo of the musical composition generated by the musical composition generating device, and/or an insertion device that inserts a ritardando or fermata in the musical composition generated by the musical composition generating device.
To attain the above object, in the second aspect of the present invention, there is also provided an automatic music composing program that is executed by a computer, comprising a bar number calculating module for calculating a number of bars of a musical composition that corresponds to a time period required by each of sections of images, a bar number-corresponding data acquiring module for acquiring bar number-corresponding data necessary to generate the musical composition and corresponding to the calculated number of bars in units of a predetermined number of bars, the bar number-corresponding data acquiring module acquiring the bar number-corresponding data that corresponds to a number of bars that is greater than and is closest to a number of bars required for generating the musical composition, a musical composition generating module for generating the musical composition based on the acquired bar number-corresponding data, a musical composition length adjusting module for adjusting a length of the musical composition such that has a length matching a time period required by a corresponding one of the sections of the images, and an output module for outputting the musical composition having the length thereof adjusted, according to each of the sections of the images.
To attain the above object, in a third aspect of the present invention, there is provided an automatic music composing apparatus that automatically creates musical compositions to be reproduc
