Description

Musical score production system using recognized musical scale {Music display system}

The present invention relates to a music score production system using a recognized scale for providing a system capable of checking whether the score data is plagiarized in comparison with known score information after generating score data through a user's voice signal.

In general, composers and arrangers with expertise in the music field use MIDI (Music Instrument Digital Interface) devices to synthesize human voices and musical instrument performances to compose and arrange music.

With the recent popularization of MIDI devices (price drop), non-professional users can also purchase MIDI devices to study music.

However, although general users can purchase MIDI devices, it is very difficult for general users to compose and arrange music using the MIDI devices because expertise is required in the use of these MIDI devices.

On the other hand, looking at the process of thinking about music by humans, not only general users but also experts may think of evil images in the studio, but at any moment in a certain place, such as going down the street, eating rice, watching TV, etc. It is common to think of music with inspiration through humming, hum, singing, or sounds heard from outside [the surroundings or sound devices, etc.], music, sound, or improvised instrument performance by oneself or others.

The music conceived as above is written in sheet music, and the composition process is performed, including human humming, humming, singing or external sound, music, sound or pitch related to improvised instrument performance, pitch height, length, tone, time signature, and Finding out the tempo and writing it down as a score is difficult for experts, but more difficult for general users.

Therefore, just by inputting the user's humming, humming, singing or external sound, music, sound, or improvised instrument playing sound into a specific device, the corresponding pitch, pitch, length, tone, beat, tempo, etc. There is an urgent need for a technology that can detect and automatically generate the corresponding basic score. For example, the user can easily and conveniently create the corresponding basic score without professional knowledge such as music composition through his own humming, humming, singing, or external sound, music, sound, or improvised instrument performance by himself or others. Technology is in great demand.

On the other hand, in order to complete the final music, the composer selects the instrument he wants to include in his or her music based on the basic score, plays it through the sound synthesis function of electronic equipment such as a synthesizer, and listens to the tone and sound of each instrument. Considering the harmony with the instrument, he writes down the score for each instrument.

However, in the conventional method as described above, the user must listen to the tones and sounds of each instrument while playing the instrument using electronic equipment to select the instrument he wants to include in his or her own music. There is a problem with making individual scores for the instruments. This is difficult for experts as well, but it is a factor that considerably lowers the motivation to compose according to the music idea by giving more difficulty to general users.

Therefore, there is a desperate need for a technology that allows a specific device to automatically generate the final score for each musical instrument layer corresponding to this basic score by simply selecting various instrument information desired by the user while the basic score is automatically generated. have.

On the other hand, recently, music has been widely used not only in the field of learning such as subject organization, but also in the field of character education and psychotherapy. On the other hand, recently, UCC (User Created Contents) produced by general users, not content providers, has gained a great response from the public, and as the concept of Web 20 spreads, users' participation in UCC has increased from the form of existing consumers. It is transforming into a consumer form, prosumer.

Therefore, even people without specialized knowledge in various fields, people with disabilities, etc. can easily and conveniently conceive, compose, and arrange user created music contents by selecting the desired instrument for the music they want to compose. There is a desperate need for technology to make it possible.

In order to solve the above-described problem, as shown in FIG. 1, Korean Patent Registration No. 10-1020557 (announcement date: 2011.03.09.) is disclosed, and a brief look at the configuration of the prior art is disclosed. In the basic score generation module based on the basic score generation module for generating basic score corresponding to humming, hum, singing, or external sound, music, sound, or improvised instrument playing sound, and instrument sound information for various pre-stored instruments It includes a final score generation module for each instrument layer for generating a final score for each instrument layer corresponding to the generated basic score, and the final score generation module for each instrument layer comprises: sound, tone, pitch and intensity according to frequency characteristics of each instrument. An instrument information DB storing instrument sound information on various instruments including, a basic sheet music input unit for receiving basic sheet music on the basic notes generated by the basic sheet music generation module, and one or more instruments selected by the user A musical instrument sound processing unit for mixing a corresponding musical instrument sound to match a basic sheet music on a basic note received from the basic sheet music input unit, and derive a frequency domain for each musical instrument layer from the mixed musical instrument sound, and the A final score generation unit for each musical instrument layer for generating the final score for each musical instrument layer corresponding to the basic score by analyzing the frequency domain for each musical instrument layer derived from the musical instrument sound processing unit based on the musical instrument information of various musical instruments in the musical instrument information DB. Consisting of a configuration that includes, the problem was solved.

However, such a conventional technique has the advantage of being able to provide a good quality sheet music according to the input sound signal by focusing on the quality for generating sheet music. There was a problem in that the actual utilization was degraded because there was no configuration that could check or search for plagiarism.

In order to solve the above-described conventional problem, the present invention is to provide a system capable of checking whether or not the sheet music data is plagiarized compared to known sheet music information after generating sheet music data through a user's voice signal. have.
