The score of "school paper ding dong" shown in FIG. 2 is illustratively shown for convenience of explanation of the present invention, and the sampling music for composition may mean all songs known in the art.

Referring to FIG. 2, a notation of a sampling song S1 corresponding to sampling music selection information received from a user is shown.

The composition program 112 may provide the user with a sampling song list to the user.

When the user selects "school paper Ding Ding" from the sampling tune list, the composition program 112 receives sampling song selection information for "school paper Ding Ting (hereinafter referred to as sampling song S1) , The sampling song (S1) can be analyzed to extract the codes and the beat.

More specifically, the composition program 112 can analyze the code corresponding to the melody line of the sampling tune S1.

For example, if the melody line in the first segment W1 of the entire segments W1 through W8 of the sampling tune S1 includes soles, soles, lah, and lahs, the composition program 112 determines that the first and second The first note corresponds to the C code, and the third note and the fourth note correspond to the F code.

In this way, the composition program 112 extracts a C code, an F code, a C code, a C code, ... , The code progression (CODE) of the C code sequence can be extracted.

At this time, the composition program 112 can extract a beat corresponding to each of the codes included in the code progress (CODE).

For example, in the composition program 112, the first C code is processed for two beats in the order of the code progress, the next F code is performed for two beats, the next C code is performed for four beats, The G code can be judged to be performed for three beats. In this manner, the composition program 112 can determine all of the beat of the last code.

Further, the composition program 112 can extract the beat of the sampling tune S1 by calculating the beat per tone of the sampling tune S1.

For example, since the first word includes four quadrants, the composition program 112 can determine the beat of the sampling song S1 as four quarters.

3 is a conceptual diagram illustrating a method of generating a melody line using selectable melodies and selectable rhythms according to an embodiment of the present invention.

2 and 3, the display device 180 according to the embodiment of the present invention includes a melody input screen 112A displaying a selectable melody, a rhythm input screen 112B displaying selectable rhythms, And the displayed new musical score screen 112C for each code by reflecting the rhythm selection.

Specifically, the composition program 112 may display a selectable melody and selectable rhythm for each of the codes extracted from the sampling song S1 via the display device 180. [ The user can select a melody and a rhythm for each of the codes to generate a new melody different from the sampling song S1.

Hereinafter, a selectable melody and a selectable rhythm for the first code (C code) that proceeds during two beats in the code progress shown in FIG. 2 will be exemplified.

The composition program 112 can display on the piano keys A3, B3, C4, ..., B5 so that the user can input only the notes corresponding to the C code on the melody input screen 112A.

For example, the composition program 112 may recognize only the user input to the piano keyboard C4, the E4, the sol G4, and the C5, and may not recognize the user input for the remaining notes .

At this time, the composition program 112 may display a note higher or lower than the notes currently displayed on the melody input screen 112A according to the user's request, and may display a note corresponding to the C code of the higher or lower notes User input can be recognized.

The composition program 112 can display the selectable rhythms R1, R2, and R3 on the rhythm input screen 112B.

For example, since the beat corresponding to the C code shown in FIG. 2 is two beats, the composition program 112 includes a first rhythm R1 including two quartets in the rhythm input screen 112B, two rhythms R1 A third rhythm R3 including a second rhythm R2 including one-quarter note notes and one quarter note, one quarter note, two sixteenth notes, and one eighth note is displayed .

If the user selects one of the selectable melodies displayed on the melody input screen 112A in sequence and selects the second rhythm among the selectable rhythms R1, R2, and R3 displayed on the rhythm input screen 112B, The melody selection program 112 selects melody selection information for melody, melody, and solo by melody and rhythm selection information for melody for the second rhythm R2, ) To display a new melody line.

In this manner, the composition program 112 can generate new melody lines for each of the codes according to chord progression, and concatenate new melody lines to complete a new song.

According to the composition method using the composition program 112 according to the embodiment of the present invention, the user can select the melody and rhythm corresponding to each of the codes by using the code progress of the already known songs, Can generate a completely different melody line.

4 is a conceptual diagram for explaining a new song generated by a composition program based on a code progression of a sampling song according to an embodiment of the present invention.

Referring to Figs. 2 and 4, a new song S2 is shown which includes a melody line that has been changed based on the sampling song S1 "school paper ding ding ".

Since the new song S2 is composed based on the code progression and the beat of the sampling song S1, the new song S2 includes a code progression and a beat such as a code progression and a beat of the sampling song S1.

However, the melody and rhythm corresponding to each of the codes of the new song S2 may be completely different from the melody and rhythm of the sampling song S1.

For example, in the first node W1 'among the entire nodes W1' to W8 'of the first node W1 and the new track S2 of the entire nodes W1 to W8 of the sampling tune S1 The melody and rhythm can be different from each other.

The C code included in the first segment W1 of the sampling tune S1 includes two tones of the fourth tune but the C code included in the first segment of the new song S2 is included in W1 ' One syllable of the quarter note, one eighth of the eighth note, and one syllable of the quarter note.

The F code included in the first segment W1 of the sampling tune S1 includes two tones of the quarter note but the F code included in the first segment of the new song S2 Contains one note of a half note.

As described above, the new song S2 has the same code progression (CODE) as the sampling song S1, but can be judged as a song having a completely different feeling because of a difference in melody and rhythm.

Also, the composition program 112 can determine the similarity between the new song S2 and the sampling song S1, and judge whether the new song S2 is plagiarized. That is, the composition program 112 can determine the similarity by comparing the melody lines of the new song S2 and the sample melody lines of the sampling songs S1 with each other, and if the similarity determination result is higher than the reference similarity The new song S2 can be judged as plagiarism.

Here, the sampling tune S1 may mean not only the tune which is the basis of the new tune S2, but also any tune which is already known.

For example, the composition program 112 includes a melody included in the first and second parts W1 and W2 of the sampling song S1, a first part W1 'and a second part W2' ') Can be compared to determine the similarity.

At this time, although the first and second nodes W1 and W2 of the sampling tune S1 include brushes, brushes, brushes, brushes, brushes, The composition program 112 includes the sampling song S1 and the new song W2 'because the first and second nodes W1 and W2' include soles, misses, brushes, waves, S2 can be judged to be low.

According to the embodiment, the composition program 112 can judge whether or not the new song S2 and the sampling song S1 are plagiarized by judging the similarity between the codes.

5 is a flowchart illustrating a composition method using a composition program according to an embodiment of the present invention.

5, the composition program 112 can provide a sampling song list to the user. When the sampling song S1 is selected by the user (S100), the sampling program S1 selects the sampling song S1 using the sampling song selection information, (Step S110).

The composition program 112 may provide the user with a selectable melody and a selectable rhythm corresponding to each of the extracted codes (S120).

If the chord-based melody and chord-specific rhythm are selected by the user, the composition program 112 generates a melody line corresponding to chord progression using the melody selection information for each chord and the rhythm selection information for each beat to compose the new song S2 (S130).

At this time, the composition program 112 may determine the similarity between the generated melody line and the sample melody line of the sampling song S1 (S140) to determine whether or not the new song S2 is plagiarized.
