Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic accompaniment apparatus capable of changing an accompaniment pattern along with the progress of a music, in addition to the function of repeatedly playing the accompaniment pattern.

[0002]

2. Description of the Related Art In recent years, automatic accompaniment devices have come to have various accompaniment patterns.
The ones with built-in functions are built into electronic musical instruments, making it easy for beginners to enjoy playing. In addition, it is usually equipped with input means such as keyboards and switches, and in addition to performing monotonous repetitions, the accompaniment pattern can be changed by the performer's instruction of chords and fill-in operations as the song progresses. You can add various modified decorations.

A conventional automatic accompaniment apparatus will be described below. FIG. 2 shows the configuration of a conventional automatic accompaniment apparatus. In FIG. 2, reference numeral 21 is an accompaniment pattern storage means for storing a plurality of accompaniment pattern data such as rhythms. 22
Is a modification decoration instructing means such as a keyboard or a switch for inputting to the accompaniment pattern for instructing the modification of the code or the pattern. 23 is an accompaniment pattern reading control means,
The accompaniment pattern data is read from the accompaniment pattern storage means 21 based on the code information and the fill-in information from the modification decoration instruction means 22, and various modifications are made and output. Reference numeral 24 denotes accompaniment pattern selection means, which is an accompaniment pattern.
It instructs the read-out control means 23 which of the accompaniment patterns in the accompaniment pattern storage means 21 is to be read out.

The operation of the automatic accompaniment apparatus configured as described above will be described below. First, the performer uses the accompaniment pattern selection means 24 to instruct which accompaniment pattern to play. According to this instruction, the accompaniment pattern read control means 23 follows a plurality of accompaniment pattern data.
The corresponding accompaniment pattern data is read from the accompaniment pattern storage means 21 in which the data is stored and output. Next, when the performer gives various modification / decoration instructions such as code designation, fill-in, variation, etc. by the modification / decoration instructing means 22, the accompaniment pattern read control means 23 causes the accompaniment pattern.
A variety of changes and decorations are performed, such as performing pitch conversion on the data and changing the accompaniment pattern data to be read, and outputting the accompaniment.

[0005]

However, in the above-mentioned conventional configuration, in order to instruct various changes to the accompaniment pattern using the change decoration instruction means 22 and complete the music, the performer himself or herself needs to play the keyboard or It is necessary to operate the switch, and even if these instructions are given during the performance of the song, or if these instructions are stored in another storage device in advance and automatically read out, the musician's own musical It had a problem that it required knowledge and advanced operating procedures.

The present invention solves the above-mentioned problems of the related art, and various kinds of information necessary for playing music such as code progress information and information such as intro / fill-in, which are characteristic for each accompaniment pattern. Change decoration data as the song progresses
By storing the data as a sequence storage means and reading out and outputting in synchronization with the accompaniment pattern, it is possible to perform the accompaniment of the music without requiring the musical knowledge of the performer or an advanced operation procedure. It is an object of the present invention to provide an automatic accompaniment device that can be performed. Further, in the present invention, when the modified decoration data is read, the tones and the like are discriminated from the melody of the performer, and a plurality of modified decoration data are selected and read out, so that the automatic accompaniment desired by the performer can be easily performed. It is an object to provide an automatic accompaniment device that can be obtained.

[0007]

To achieve this object, an automatic accompaniment apparatus of the present invention comprises an accompaniment pattern storage means for storing a plurality of accompaniment pattern data such as rhythms, and the accompaniment pattern. Sequence storage means for storing a plurality of various modified decoration data of the accompaniment pattern for each accompaniment pattern stored in the sequence storage means, and an accompaniment pattern from the sequence storage means. A sequence read-out control means for sequentially reading and outputting the modified decoration data as the music progresses, an input means such as a keyboard for playing a melody, etc.
The tonality discrimination switching means for discriminating the tonality of the music from the performance data fetched from the input means, and for instructing the sequence reading control means to switch a plurality of changed decorative data to be read, -Accompaniment pattern read control means for reading out the accompaniment pattern data from the accompaniment pattern storage means based on the modified decoration data read by the cans read control means, and applying various conversions for output. And has the configuration.

[0008]

With this structure, modified decoration data according to the progress of various musical pieces necessary for playing a musical piece such as code progress information, intro or fill-in information, which is characteristic for each accompaniment pattern. However, the tonality is discriminated by the player's melody performance, and the tonality is freely selected and read out and output in synchronization with the accompaniment pattern. The performer can concentrate on melody performance and ad lib, and can enjoy the performance with effective accompaniment as a background.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 11 denotes accompaniment pattern storage means for storing accompaniment pattern data such as rhythm.
Reference numeral 12 is a sequence storage means for storing a plurality of various modified decoration data of the accompaniment pattern for the accompaniment pattern stored in the accompaniment pattern storage means 11. 13 is
