If so, the routine proceeds to step 124, where a code tendency name of "Other" is displayed. That is, in the recommendation table (L), a plurality of code trend data other than the code trend data displayed in step 114 are selected and read from a data group (for example, P ₁ ) corresponding to the style name data related to the selection. The code tendency name is displayed in the list box LBa as shown in FIG.

Next, in step 124, it is determined whether a code tendency name has been selected. If the result of this determination is affirmative (Y), it means that any code tendency name has been selected, and the routine proceeds to step 122. If the determination result of step 124 is negative (N), the process waits for a selection operation.

In step 122, the code tendency name related to the selection is displayed in the display frame CTD as shown in FIG. 7 based on the code tendency data related to the selection. Then, the process proceeds to step 126.

In step 126, the code tendency number in the selected code tendency data is set in the storage unit CDN. Then, the process proceeds to step 86 in FIG.

At step 86, it is determined whether or not there is a code candidate extraction start operation. The result of this determination is positive (Y)
If so, the process proceeds to step 88, where a code candidate extraction process is performed. In this case, the code database (M) in FIG. 11 is used instead of the code database (D) in FIG. That is, in the code database (M), the storage unit CD
From the data group having the same code tendency number as the code tendency number of N, code data conforming to the melody data in the storage unit MD is selected one after another according to the flow of the melody, and is stored in the storage unit CD as code candidate data. The processing of the selection flag data SF at this time is the same as described above. Then, similarly to the process of storing original chord progression CP ₁ and chord progression data CP ₂ in the storage unit CP, and a process for performing encoding processing display as shown in FIG. 9 on the screen of the lower screen 12B described above Do.

After step 88, the processing after step 90 is executed in the same manner as described above, and the process returns to the routine of FIG.

According to the embodiment described above with reference to FIGS. 11 and 12, after selecting a desired accompaniment style on the screen of FIG. 8, on the screen of FIG. 7, it is possible to select a chord tendency adapted to the selected accompaniment style. it can. Then, the storage unit C
The chord progression data CP ₂ of P, with the chord progression data suitable for the melody data relating to and enter a code tendency of the selection is obtained, the and the user has the accompaniment style and fits the chord tendency relating to the selected Accompaniment data that suits your taste is obtained.

Therefore, as a user, the trouble of investigating the tendency of a chord adapted to the accompaniment style can be omitted, and editing work after data generation can be simplified.

The present invention is not limited to the above embodiment, but can be implemented in various modified forms. For example, the following changes are possible.

(1) Data such as a chord tendency table, a recommendation table, an accompaniment database, a chord database, and a music database are not prepared in advance in the ROM 24 or the like, but can be created by the user and written in the RAM 26 or the like. Alternatively, the present invention may be implemented based on data written in the storage means.

(2) Data such as a chord tendency table, a recommendation table, an accompaniment database, a chord database, and a music database may be stored in a mixed form, instead of being stored individually.

(3) The means for inputting the melody data is not limited to the keyboard type electronic musical instrument, but may be any type of electronic musical instrument such as a stringed musical instrument type or a wind instrument type. Instead of inputting from the external storage device 34, melody data stored in the ROM 24 may be selected and input.

(4) The instruction on the display surface is not limited to an instruction by a cursor moving type instructing means such as a mouse, but may be an instruction by a touch of a hand or the like.

(5) The accompaniment style name or chord tendency name is additionally displayed by selecting “Others”, but it is also possible to display all items including the additional display at once.

(6) When displaying the accompaniment style name (or chord tendency name) after selecting the chord tendency name (or accompaniment style name), it is recommended to change the display color or display the priority order. The degree may be recognizable. The priority can be set higher as the number of selections increases.

(7) After displaying the chord tendency name (or accompaniment style name), the accompaniment style name (or chord tendency name)
Is displayed, but all chord tendency names and all accompaniment style names may be displayed on one screen.

(8) The code database may be a single database instead of being separated for each code tendency name.
When extracting code data from a single code database, it is possible to extract code data that conforms to the selected code tendency in accordance with rules predetermined for each code tendency.

(9) Instead of displaying the chord tendency name (or accompaniment style name) using the list box, a separate window may be opened and displayed there.

(10) The recording medium on which the program is recorded is not limited to the ROM 24, but may be a recording medium (HD, FD, CD, DVD, MO,
Etc.) can be used. In this case, the program recorded on the recording medium is transferred from the external storage device 34 to the RAM 26. Then, the CPU 22 is operated according to the program stored in the RAM 26. By doing so, it is possible to easily add a program, upgrade a version, and the like.

(11) Programs and various data necessary for carrying out the present invention can be transferred from a server computer or the like to a RAM 26 or a RAM via a communication network (for example, LAN (local area network), the Internet, a telephone line, etc.) and a communication interface. It may be taken into the external storage device 34 in response to a download request.

(12) A small computer corresponding to the personal computer 10 may be built in the electronic musical instrument 14 or integrated with the electronic musical instrument 14.

(13) The present invention can be applied to a case where a chord progression and an accompaniment style are added to a selected song (melody) in a karaoke apparatus.
