Processor devices functioning as tone-generation-related processing elements, such as a keyboard, tone generator and speaker, are connected to a star-type network. Desired processing elements are logically connected (e.g., a keyboard is logically connected to the input side of the tone generator and a speaker is connected to the output side of the tone generator) in an internal network, so that a tone generation system can be built. Each processor device possesses a content file, and each of the processor devices has a table storing, for each of the processor devices, information indicating whether the content file possessed thereby can be supplied. If a particular one of the processor devices does not possess a content file to be used, the particular processor device extracts, from the table, another processor device capable of supplying the content file to be used and receives the content file from the extracted processor device.

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.

Method and device for automatic music composition employing music template information

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 &ldquo;a&rdquo;, &ldquo;b&rdquo;, &ldquo;c&rdquo;, &ldquo;d&rdquo;, &ldquo;e&rdquo;, &ldquo;f&rdquo; (each letter means one kind of chords) for a music is selected by a user. If two chords &ldquo;c&rdquo; and &ldquo;d&rdquo; among the series of chords &ldquo;a&rdquo;, &ldquo;b&rdquo;, &ldquo;c&rdquo;, &ldquo;d&rdquo;, &ldquo;e&rdquo;, &ldquo;f&rdquo; are changed into different ones, according to the user's preference or to make them more appropriate to the motif melody, the chord &ldquo;b&rdquo; adjacent to the changed &ldquo;c&rdquo; is automatically corrected into &ldquo;b*&rdquo; so that both chord connections from &ldquo;a&rdquo; to &ldquo;b*&rdquo; and from &ldquo;b*&rdquo; to the changed &ldquo;c&rdquo; can be more musically natural. Similarly, the chord &ldquo;e&rdquo; adjacent to the changed &ldquo;d&rdquo; is automatically corrected into &ldquo;e*&rdquo; so that both chord connections from the changed &ldquo;d&rdquo; to &ldquo;e*&rdquo; and from &ldquo;e*&rdquo; to &ldquo;f&rdquo; can be more musically natural.

An automatic music composing apparatus is provided, which is capable of generating music with a high degree of completion in synchronization with images and in a time that matches the length of images. The automatic music composing apparatus automatically creates musical compositions to be reproduced as a background for images. A number of bars of a musical composition that corresponds to a time period required by each of sections of images is calculated. Bar number-corresponding data necessary to generate the musical composition and corresponding to the calculated number of bars is acquired. The musical composition based on the acquired bar number-corresponding data is generated. The generated musical composition is outputted according to each of the sections of the images.

Automatic music composing apparatus and automatic music composing program

Automatic composition apparatus and method are provided which are capable of modifying a rhythm pattern to provide a wide variety of rhythm patterns only through simple setting, and a storage medium that accomplishes this function is provided. Characteristics of a rhythm pattern of a piece of music to be composed are established. Characteristic data that match the established characteristics are retrieved from a rhythm pattern database rhythm pattern database comprising a plurality of rhythm patterns and characteristic data indicating characteristics of each of the rhythm patterns. One of the rhythm patterns is selected, that corresponds to the retrieved characteristic data. Accordingly, different rhythm patterns having the same characteristics can be easily obtained. Further, composition conditions to be applied to a whole piece of music to be composed are established, and the established composition conditions are allocated to each of sectional elements that constitute the piece of music, for example, a passage, a phrase, or a measure, and the composition conditions for the whole piece of music, in other words, distributed among the respective passages, phrases or measures. Therefore, a rhythm pattern having different characteristics may be obtained by changing only the characteristics of the whole piece of music, thus assuring an improved efficiency with which the user operates the apparatus.

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.

In a fingering information analyzer, tone pitch information indicative of each tone pitch of a series of musical notes supplied from a flexible disc or a performance information memory is analyzed to produce fingering information indicative of a performance finger for each of the musical notes. The fingering information is mixed with the tone pitch information and memorized in a fingering memory. When the fingering information is reproduced, a performance finger for each of the musical notes is determined in accordance with a changing direction or variation width of the tone pitch information continual in time series and a changing condition of white and black keys based on the tone pitch information. The tone pitch information and fingering information memorized in the fingering memory is read out in accordance with progression of a musical tune and adapted for performance of the keys on a keyboard and for indication of the performance finger.

In a portable communication terminal apparatus, a transmitter and receiver conducts either of a transmission and receipt of a message. A tone generator generates a sequence of tones to sound a music melody of a song in association with either of the transmission and the receipt of the message. A music composer is provided for inputting a motif melody comprised of a rhythm and a pitch and for composing the music melody of the song based on the inputted motif melody. The music composer may automatically input either of the rhythm and the pitch of the motif melody. A display device displays the inputted the motif melody in a sequence of beat points for editing.

Portable communication terminal apparatus with music composition capability

In accordance with a rhythm of a main melody, a auxiliary-melody or counter-melody creating rhythm pattern is supplied which indicates timing of respective hit points of a plurality of tones in the auxiliary or counter melody. Predetermined important hit points and unimportant hit points in the supplied rhythm pattern are discriminated from each other. Any one of component notes of chords, specified by a previously-supplied chord progression, is allocated to each of the thus-discriminated important hit points, while any one of scale notes, corresponding to previously-supplied scale information, is allocated to each of the unimportant hit points. Thus, an auxiliary or counter melody is created on the basis of the notes allocated to the individual hit pints.

Automatic musical composition method and apparatus

An automatic music composing apparatus comprises: a memory that stores a plurality of chord-progression data in a specific key; an input device that inputs motif melody data; a selector that selects at least one chord-progression data from the memory; a detector that detects a key of the input motif melody data; a transposer that transposes the selected chord-progression data into the detected key in accordance with relation between the detected key and the specific key; and a melody data generator that generates a melody in the detected key in accordance with the input motif melody data and the transposed chord-progression data.

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.

Apparatus and method for generating auxiliary melody on the basis of main melody

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.

Automatic musical composition apparatus and method

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. In place of the similar rhythm pattern, a rhythm pattern which is contrastive to the motif rhythm pattern may be provided to obtain a length of melody contrastive to the melody motif.

Apparatus and method for creating melody and rhythm by extracting characteristic features from given motif

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. Further, since the melody generated in the first stage only includes pitches that meet less strict melody generating conditions, the same melody is less likely to be rejected in the evaluation of the second stage, assuring high efficiency with which melody generation can be accomplished.

The display screen displays measure windows corresponding to the first through fourth measures for a melody to be composed. By clicking the play switch on the screen, a background accompaniment performance covering the four measures is played back to indicate the beats in the progressing tempo, thereby representing the rhythm speed. In time to the accompaniment progression, the user inputs note time points by tapping the input switch such as a space key in the keyboard to constitute a rhythm pattern for a melody progression. The measure window has a time axis in the horizontal direction and a pitch axis in the vertical direction. The tap-inputted note time points are exhibited at the corresponding positions along the time axis from left to right. Each point is dragged with the mouse pointer upward or downward to an intended pitch level, thereby establishing a pitch thereof. Alternatively, a pitch variation curve is drawn in the measure window plane to be sampled at the note time points, thereby establishing pitches of the respective note points. Only the pitches of important notes may be inputted, and the remainder may be automatically created in the apparatus according to a prepared algorithm.
