More specifically, the present invention provides a simple, light weight wireless terminal (more preferably a mobile phone) without using a heavy and expensive notebook computer for a specific additional service using wireless data such as a mobile song accompaniment / music performance service. It provides song accompaniment data only by the terminal), and provides a song accompaniment / music performance service that can be played while pressing the keypad of the wireless terminal with a finger while listening to music.

In general, song accompaniment refers to the sound of various musical instruments and specific sounds to help a singer, and with the development of electronics, an accompaniment performed by many people through electronic processing devices.

Such a device provides an accompaniment by combining and signaling a specific song by digitizing sound source waveforms that digitize sound elements such as musical instruments constituting an accompaniment that does not include human voice. In addition, by displaying a background image and lyrics in accordance with a song accompaniment on a TV (TV) on such a device, it is easy to see the karaoke that provides a service by encouraging the singer, and confirming the lyrics. In the song accompaniment apparatus, there is a memory including song accompaniment data for each song. When accompaniment is requested, a memory including accompaniment data for the corresponding song must be additionally installed.

In addition, in order to perform a song accompaniment in the outdoors for the mobility of such a general song cycle, many songs are stored in a portable device and connected to an amplifier or a TV by wire or wirelessly. However, it is difficult to add new songs quickly as new songs are released, and after a certain period of time, new songs must be replaced with devices.

In recent years, the Internet has been commercialized according to the development of wired data communication, and digitally converts not only the accompaniment data but also the song itself containing the voice of the singer. You can listen to songs on your old computer. In particular, the acquisition of music data through a data communication network such as the Internet can convert various types of music data types according to needs, thereby processing data according to a device so that music can be listened to.

However, since most of these devices are made through a computer, a computer installed in a home or the like or a notebook computer including a music card function is essential. Recently, portable devices have been developed that allow users to listen to songs by downloading compressed music files from their computers via cables, but they have become very popular due to the large amount of data. There was a disadvantage to affect.

Nowadays, with the development of wireless communication, in particular, the development of wireless data communication, a computer connected by wire in the home is used outdoors, so that only a mobile phone terminal and a laptop computer can access a data communication network including the Internet, even if it is outdoors. After searching, you can download the searched data.

However, the conventional song accompaniment system using a mobile phone network can download music files through a mobile phone terminal and a laptop computer to listen to music, but a person who wants to easily listen to the song accompaniment anywhere should always carry a laptop computer. Therefore, there was a limitation of mobility, and the portable song accompaniment without the existing new song addition function could not be added to the data for the new song was also unsatisfactory in use. In addition, in order to acquire song accompaniment data wirelessly in such a song accompaniment system, an expensive notebook computer as well as a mobile phone terminal is required, thereby causing an uneconomic problem.

On the other hand, thanks to the development of the data communication network, the MP3 (Music Player-3) file can be downloaded by accessing the Internet through a mobile phone terminal. However, the MP-3 file has a size of about 3 to 5M Byte per song. There is a problem that the transmission speed is very slow to download to the portable terminal, and also takes up a lot of memory capacity.

The present invention has been proposed in order to solve the problems described above, and retrieves a music file that a subscriber (or user) likes anytime, anywhere from a heterogeneous network interworking system (preferably Internet / intranet and wireless communication network). A song accompaniment / music performance service apparatus for enabling song accompaniment and music performance in a wireless terminal, and a method thereof, and a computer-readable recording medium recording a program for realizing the method.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a hardware system to which the present invention is applied and shows a configuration of a heterogeneous communication system in which an internet / intranet and a wireless communication network are interworked.

First, the procedure for interworking the Internet / Intranet and the wireless communication network will be described.

As shown in FIG. 1, a heterogeneous communication system in which an internet / intranet and a wireless communication network are interworked according to the present invention includes a mobile telephone network and an intranet within the enterprise in the signal matching unit 30 and the voice conversion unit 40. In conjunction with the same wireless communication network can provide a song accompaniment / music performance service.

Here, the mobile telephone network includes a switching center (MSC), a base station (BTS) 20, a control station (BSC), and the like, and transmits and receives signals with the mobile station (MS) 10.

However, the mobile telephone network as described above is only a technique well known in the art, so a detailed description thereof will be omitted here. However, the signal processing function will be briefly described.

A mobile station (MS) 10 is a terminal that a user can carry and communicate with while moving. The mobile station (MS) 10 is within a range of an arbitrary base station 20, and information of the mobile station 10 is controlled by the base station 20 and a control station controlling the same. BSC) is transmitted to the switching center (MSC), and information transmitted from the switching center (MSC) is transmitted to the mobile station 10 via the control station (BSC), the base station 20.

The mobile station 10 may be a cellular mobile communication terminal, a next generation mobile communication terminal such as a personal communication system (PCS) terminal, an international mobile telecommunication (IMT-2000), a universal mobile telecommunication service (UMTS), or an individual. And personal digital assistants (PDAs).

In general, a mobile telephone network uses a data burst message of a paging channel of a code division multiple access (CDMA) mobile telephone system when received, and data of a forward traffic channel when a user is busy. Send the text message as a burst message. In addition, when a text message is transmitted, a data burst message of an access channel is used, and when the call is busy, a data burst message of a reverse traffic channel is used.

The messages transmitted and received by the mobile station 10 are connected to the switching center MSC through the base station 20 and the control station BSC for high frequency signal processing and call processing.

The base station (BTS) 20 connects the mobile station 10 to a control station (BSC), communicates with the mobile station 10 via wireless, and performs a wired / wireless conversion function of communicating with the control station (BSC) by wire. do.

The control station BSC coordinates the connection between the base station 20 by connecting the base station 20 to the switching center MSC, and serves as a signal processing function for communication between the base station 20 and the switching center MSC.

The switching center (MSC) processes the mobile communication subscriber call, accesses the control station (BSC), performs call setup and release functions of the mobile station 10, and performs various functions related to call processing and additional services.

In the system of interworking the Internet / Intranet and the mobile telephone network as described above, when the signal matching unit 30 and the voice conversion unit 40 interoperate heterogeneous networks to provide a song accompaniment / music playing service, The voice compression schemes supported by the mobile telephone networks are different and cannot be linked as they are. Therefore, in order for the signal matching unit 30 and the voice changing unit 40 to mutually interoperate with each other, the network is converted to a voice format that can be commonly supported by one of two different networks, and then connected to another network. It can be converted and linked again in a way that supports the characteristics of the network.

The music file used in the song accompaniment / music performance service uses a virtual orchestra system (VOS) music file.

VOS music files can be created from MIDI (Musical Instrument Digital Interface) files. This process is described in more detail in FIG. 8 below.

MIDI refers to the international unification standard for electronic musical instruments established for the compatibility of data transmitted and received during electronic musical instruments. Most electronic musical instruments have a function of transmitting and receiving data based on MIDI standards. Here, among the electronic musical instruments, the household can be divided into three types: electronically opened, electronic piano, and electronic keyboard, and all electronic instruments are configured to synthesize waveforms by an analog circuit or a digital circuit.

MIDI is the world's universal standard for transmitting musical instrument performances as digital signals. A 5-pin dedicated cable can be used to send and receive channel messages and system messages. Channel messages are mainly played data such as scale, sound field, strength, and tone. Send the program's conversion data information.

By the way, in recent years, the data sharing with a personal computer (PC) has been increased to control the electronic musical instrument with a PC, and to control the electronic musical instrument with a MIDI terminal attached to the PC, a signal used inside the PC is used as a MIDI signal for the electronic musical instrument. You need to convert it, and in order to do that you need a MIDI interface. There are two types of MIDI interfaces, an intelligent type having a central control unit (CPU) and a non-intelligent type.

At present, since channel information can transmit 16 different channel information through a single cable, it is possible to perform ensemble by automatic playing of several electronic musical instruments by MIDI signal from computer, and at the same time, playing multiple electronic musical instruments by yourself It is possible.

Song accompaniment (karaoke) files, on the other hand, these VOS music files are inserted into the lyrics and beat sync part.

Accordingly, in the present embodiment, it is assumed that the song accompaniment / music performance service apparatus 14 shown in FIG. 2 that supports the VOS interface for the song accompaniment / music performance service is provided in the mobile station 10.

Web server (information provision server) 50 provides a song accompaniment (karaoke) / music performance program, and provides a function for the user to perform a song accompaniment (karaoke), music performance or ensemble.

Mobile station 10 is connected through a web server 50 and a heterogeneous communication network (internet / mobile phone network), download and install the song accompaniment (karaoke) / music performance program, and store the song accompaniment (karaoke), personal performance Alternatively, it is possible to perform the ensemble with multiple users.

On the other hand, as shown in FIG. 11, based on the VOS music file and the song accompaniment (karaoke) music file, a virtual environment (Internet environment), that is, station A (for example, the United States), station B (for example, , Japan), Country C (e.g., Korea) ... In Country N, you can sing together at the same time as your imaginary users, or you can play your own instrument and play the entire music together. This is to synthesize the user's voice and the accompaniment sound, or superimpose the playing effect corresponding to the playing operation of the background sound provided by the web server 50 for the designated sound and the sound other than the designated sound which the user selects and indicates.

Of course, in order to enable such an environment, the web server 50 produces a VOS music file in which musical notes are divided by musical instruments, such as actual performances, from a MIDI file or a corresponding source. Insert a part to create a song accompaniment (karaoke) music file representing the song lyrics, the user's song order, and other accompaniment sounds for the music to provide to the user.

As shown in FIG. 2, the mobile station 10 includes a song accompaniment file (i.e., a karaoke file) indicating a song lyrics for the music, a user's song order, and other accompaniment sounds through a wireless communication network, and a user's performance of the music. Song accompaniment / music performance file supply unit for receiving music performance files (ie, virtual orchestra system (VOS) files) indicating designated sounds to be played according to the timing of each instrument and other background sounds (that is, virtual orchestra system (VOS) files). Display unit 12 for displaying the lyrics and song order of the karaoke file, and displaying each note of the corresponding music in the VOS file as an electronic score indicating the order of performance. An input device (microphone or keypad) 11 for inputting a user's voice according to the song order and a performance operation from the user according to the playing order for each note of the electronic score; It stores karaoke files and VOS files, provides song lyrics and song order among karaoke files to the display device 12, and converts each note for the instrument to play the corresponding music among the VOS files into an electronic score indicating the order of performance. It is provided to the display device 12, and outputs the user's voice input by the input device (microphone) 11 and the accompaniment sound other than the user's voice among the corresponding music, and the performance operation by the input device (keypad) 11 Synthesized and assigned a user's voice and accompaniment sound provided by the song accompaniment / music performance processing unit 142 and the song accompaniment / music performance processing unit 142 for outputting the designated sound and the background sound other than the designated sound among the corresponding music. And a speaker 13 for outputting the music played by the music output device 143 by synthesizing the sound with the background sound.

Here, the user's performance of the music playing service using the keypad of the terminal.

The song accompaniment / music performance file supply device 141, the song accompaniment / music performance processing device 142, and the music output device 143 constitute the song accompaniment / music performance service device 14.

First, when a service user calls the web server 50 through a wireless communication network and requests a song accompaniment / music performance service, the service process for karaoke / music performance in the web server 50 will be described.

Here, it is assumed that the song accompaniment / music performance service device 14 is mounted inside the mobile station 10 of the service user.

If a service user (ie, a customer who wants to play karaoke / music) sends a call to the web server 50 (for example, press and hold "1 + SEND" or "1", and of course, modify it in other ways as well. If possible), the web server 50 operates an automatic response system (ARS) to provide a song accompaniment / music performance service menu to the user. In this case, the web server 50 may provide a karaoke / music performance service menu to the user through voice or short message service (SMS).

Of course, it is apparent that the web server 50 may provide a guide person instead of an ARS, so that the guide person can directly record all matters related to the service. However, since such a method is only a well-known technique, it will be left out in this embodiment.

Karaoke 2. Music performance 3. Operator Information0. Information Use

Of course, it is apparent that the karaoke / music service menu may be provided in the mobile station 10 itself. In this case, it is apparent that the menu download process is omitted, and the service user can immediately request a desired song through his karaoke / music performance service menu.

If the service user selects the karaoke ("1") or music performance ("2") service, the web server 50 reads the list index stored in the database 60 and transmits the list index to the mobile station 10. In the list index, the list is divided into a large category (type of song (pop song, song, etc.)), a middle class (life name), a small category (song name), and the like, according to the user's stepwise selection request. The list index is read and transmitted sequentially. In addition, unlike the staged list index transmission, when the user inputs the first letter of the song name, the web server 50 extracts only the song containing the corresponding letter from the list index of the database 60 and indexes it. Of course, it can be configured to transmit to the mobile station 10 is obvious.

Of course, the mobile station 10 characterizes and displays the list index on the display device 12 so that the user can select and download a specific song from the received list. At this time, it is obvious that the downloaded song may be stored in the memory and the later song download process may be omitted.

Here, of course, the karaoke service can be performed solo or chorus, it is obvious that the music performance service can also be played alone or a large number of users orchestra.

Meanwhile, as the input device 11 of the mobile station 10, not only a keypad, but also a keyboard, a piano keyboard form, a keyboard instrument, a string instrument, a percussion instrument, a wind instrument, a drum, and other application display means may be used according to a mode (interface display form) selection. It may be obvious.

As an interface, when the terminal keypad is used, the keypad is displayed on the screen so that the performance instruction bar falls on the keypad on the screen in sequence, and when the keyboard is connected, the performance indicator bar is sequentially connected on the keyboard by connecting the keyboard on the screen. Can fall off. Of course, it is obvious that the same may also be applied to other application means.

In addition, the apparatus of the present invention can be used for performance using other music files in addition to the song accompaniment / music performance file.

First, a song accompaniment service process will be described in detail with reference to FIG. 3.

3 is a flowchart illustrating an embodiment of a song accompaniment service method according to the present invention.

As shown in Figure 3, the song accompaniment service method according to the present invention, first, the service user (that is, a customer who wants to receive karaoke service) is a karaoke / music service representative number (for example, "1 + SEND" or Long press "1", of course, it is obvious that it can be transformed in other ways) and call the karaoke service ("1") (301), the web server 50 in the above karaoke / music performance service Provide a menu to the user. Thereafter, the service user can select a desired song through the karaoke / music performance service menu (302), download the corresponding karaoke file (303), and store it in the memory (304). Of course, the service user may immediately request a desired song through its own karaoke / music performance service menu and store the song in the memory, or the above process may be omitted when the song is stored in the memory.

Thereafter, when the service user reads the karaoke file for the desired song (305), and plays the corresponding song (306), the mobile station 10 displays the song lyrics on the display device 12 (307), the song The lyrics are accompanied by a song sequence (for example, the lyrics of the song are blinking in bold, or in bold). The accompaniment sound for the song is output.

Next, when the user looks at the song lyrics according to the song order and sings the song 308, the mobile station 10 synthesizes the user's voice and the accompaniment sound and plays the corresponding music (309). In this case, the degree of achievement (eg, expressed as a score, very good, excellent, normal, or poor) for the song may be displayed on the display device 12 (310).

Now, the music playing process will be described in detail with reference to FIG.

As shown in Figure 4, the music playing service method according to the present invention, the service user (that is, a customer who wants to receive a song playing service) is the karaoke / music playing service representative number (for example, "1 + SEND") Or press and hold "1", of course, it is obvious that it can be modified in other ways) and request a song playing service ("2") (401), the web server 50 in the above karaoke / music Provide the user with a performance service menu. Subsequently, the service user can select a desired song through the karaoke / music performance service menu (402), download the corresponding karaoke file (403), and store it in the memory (404). Of course, the service user may immediately request a desired song through its own karaoke / music performance service menu and store the song in the memory, or the above process may be omitted when the song is stored in the memory.

In other words, the web server 50 constructs a list of music pieces currently stored in the database 60 and provides them to the user, and receives a song to be played through the input device (keypad) 11 from the user. Subsequently, the web server 50 provides the VOS file produced by the following musical instrument division and storage process (see FIG. 8) to the song accompaniment / music performance file supply device 141 of the mobile station 10. The mobile station 10 reads the instrument performance information from the VOS file of the song accompaniment / music performance file supply device 141 and loads it into a main memory device such as a memory fast enough for access to use the read instrument performance information in real time. do.

Next, referring to the music playing process in the mobile station 10, the mobile station 10 provides the user with a list of instruments constituting the song selected by the user and receives one of the instruments from the user (405).

Next, the electronic score for the musical instrument to be played by the user is displayed on the screen of the display device 12 (406). At this time, since the length of the song is often relatively long to be displayed on one screen, as the time progresses, the electronic sheet music of the place to be played is scrolled and shown. The display process of the electronic sheet music is shown in FIG. That is, when the musical notes of the "A" part are expressed in electronic score, they are converted as "B".

Subsequently, when the user plays through the input device (keypad) 11 according to the electronic score displayed on the display device 12, the song accompaniment / music performance processing unit 142 recognizes the performance input by the user ( 407).

Thereafter, the song accompaniment / music performance processing unit 142 outputs a note (ie, a designated sound VOS output message) corresponding to the user's input key input in real time to the music output device 143 (408). For musical instruments not to be played, notes (ie, background sound VOS output messages) are automatically output to the music output device 143 (409). At this time, in the case of the non-simplified electronic sheet music, for example, when the performance is performed on a real MIDI instrument, the input is sent without going through a simplified algorithm. On the other hand, in the case of the simplified electronic sheet music, the closest note is currently output. For example, as shown in Fig. 6, when the "degree" key is pressed at 100 seconds (C) after starting the performance, there is a "five octave degree" note (b) at the position of 90 seconds of the original song and the 105 seconds of the original song. When there is a "6 octave degree" note (a) at the position, the note (a note) at a position of 105 seconds closer to the user's input is determined as the note to be played.

Finally, the music corresponding to the note (VOS output message) of the instrument played by the user in the music output device 143, and the instrument automatically played by the song accompaniment / music performance processing unit 142 not played by the user Mixing the sound corresponding to the note of in real time and outputs through the speaker 13 (410). In this case, as shown in FIG. 7, the degree of achievement of the played song 7b compared to the original song 7a with respect to how accurately the user performed the performance compared to the original song standard may be shown as shown in FIG. 7.

As described above, in the case of playing music alone, displaying the electronic score (406), receiving a performance input from the user (407), outputting the designated sound of the selected instrument (408), not playing The automatic output of the designated sound of the instrument 409 and the ensemble processing 410 are repeatedly performed until the performance is completed.

On the other hand, when two people play music, the first and second users mix in real time the designated sound of the instrument selected by the first user and the designated sound of the unplayed instrument to the designated sound of the instrument selected by the second user. An orchestra ensemble is possible by letting the computer play the notes playing on each other. In addition, it is obvious that orchestra ensemble can be performed in the same manner even when several people play music.

FIG. 8 is a detailed flowchart illustrating a process of dividing and storing a musical note for each musical instrument in the music playing service method according to the present invention, and illustrates a procedure of creating a VOS file in the web server 50. FIG. 12 is a diagram illustrating an embodiment comparison showing delta time information of a digital music file and absolute time information in a performance VOS file during musical instrument segmentation and storage procedures according to the present invention, and FIG. According to one embodiment, a detailed flowchart of a process of converting delta time information of a digital music file into absolute time information during a process of dividing and storing musical notes according to musical instruments.

As shown in Fig. 8, the process of producing a VOS file in the web server 50 according to the present invention comprises, first, a song stored in a MIDI file (music file created by a MIDI format used as a source of a music playing system). In order to obtain necessary information from the messages, MIDI messages are separated by type and loaded on the database 60 (801). For reference, this message type can be largely divided into control messages (for example, volume messages, effects, etc.), performance messages, and instrument setting messages. In the MIDI file, the time domain for these messages is defined as delta time. It is. Herein, delta time means that time information of all messages is defined as a difference (interval) value from previous time information (see FIG. 12).

In producing the VOS file of the present invention, in order to enable virtual orchestra performance, the MIDI format message information defined in delta time is converted into absolute time (802).

The meaning of the delta time and the absolute time mentioned above can be easily understood from the time information display of the performance message illustrated in FIG. 12. That is, the time information indicated on the left side of each performance message in FIG. 12 is delta time, and the time information indicated on the right side is absolute time.

In addition, the process of converting the delta time to the absolute time as described above can be easily understood from the flowchart of FIG. 13. That is, after performing an initialization process such as setting an initial delta time value (usually "0") to an absolute time initial value (121), it is determined whether a message with unconverted delta time information exists (123), If present, the previous absolute time value plus the current conversion target message delta time value is determined to be the current conversion target message absolute time value (125), and then the message with unconverted delta time information no longer exists. By repeatedly performing the determination step 123 until not, the delta time information of the MIDI format messages is converted into absolute time.

You can then configure the note messages to be played by the user, for example, by configuring the user to play only one specific instrument, or by switching the instrument over time, or by playing multiple instruments at once. You can also create a VOS file that you configure to do this.

In addition, in some cases, it may be necessary to have a performance control input device capable of playing all octaves, such as a MIDI instrument, so that the performance can be performed without any special simplification. Therefore, it may be necessary to simplify complex playing procedures in order to make it easier for non-experts to play a particular instrument without prolonged practice, or conversely, more complicated manipulations than normal playing procedures for experienced professionals. It may be necessary to complicate the music score to be performed by the process (803).

For example, referring to FIGS. 9 and 10, the case of simplifying the score is as follows.

Referring to FIG. 9, the removal of an octave from a note may cause all notes to be attributed to one octave (see "g" in 9a and 9b). It is also possible to place semitones in the notes in the notes (see "e" in 9a and 9b). Through this process, the original sheet music 9a can be simplified into a new type of electronic sheet music 9b (804). However, in practice, the electronic score 9b has original song information for reproducing the correct performance sound during the user's performance operation, and information for displaying a simplified performance instruction.

In addition, in the electronic sheet music 9b newly generated through the above process, if necessary, it is possible to additionally modify the arrangement of the notes or the deletion of the notes to be played (805). For example, as shown in FIG. 5, the difficulty can be adjusted by deleting a note using an editor.

On the other hand, in the case where the original song itself has an idle time that does not require a performance operation, or in the electronic score 9b to which the above-mentioned arrangement change or deletion of notes is applied, additional advertisement information (i.e., , Time periods for inserting promotional texts, images, and sound clips to specific companies, products, and songs. In such a case, by designating the presentation time of the advertisement information together with each advertisement information, the usefulness can be enhanced by being included in the VOS file serving as the source of the performance.

The VOS file is finally generated through the above process (806).

According to the present invention, a character or the like can be given to each player or soloists / singers, and the character can be changed according to the performance amount or performance. It is connected online, so it can be prepared for others.

For example, if the user's performance is high, the score goes up and proportionately changes the character, picture, or figure of a person, animal, or grows or transforms, so that the character is recognized as a kind of pet growth like a pet. You will have a structure that fits well. If the pet character does not care for the pet character, such as getting sick or die, or failing to continuously score, the pet character may be depressed, reduced, or deteriorated to stimulate the user's continuous interest.

In addition, a user's high performance can cause the character to dance or rejoice, make gestures, gestures, gestures, congratulations or encouraging voice messages, firecrackers, screen colors, or flickering images. You can also use methods. Also, depending on the user's performance, a method may be used to enable the associated interesting game or provide superior status or powerful weapons or means in the linked game. In addition, depending on the user's performance, they want to buy products in connection with Internet commerce sites by mailing products, paying entry tickets, qualifying to participate in events, paying money or paying electronic money. The means of stimulating the user's desires by buying things in the electronic money is also very useful.

As described above, the present embodiment has been described assuming a virtual orchestra system (VOS) file as a song accompaniment / music performance file, but the present invention is not limited thereto, and the present invention uses a MIDI music file. Likewise, a song accompaniment (karaoke) / music performance service may be provided through a wireless terminal, and in this case, it should be apparent that the same effects as those of the present embodiment should be regarded as the same.

In addition, in the present embodiment, a song accompaniment (karaoke) service and a music performance service have been separately described for convenience of explanation, but this is merely described separately for convenience of explanation to help understanding of the present invention, and each may perform an independent service. Obviously, the method of the present invention as described above can be implemented as a program and can be read by a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk). And the like).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention can realize miniaturization and low price of a song accompaniment / music performance device by a wireless terminal, and can enjoy karaoke / music performance by selecting a favorite song of a wireless terminal subscriber (or user) anytime and anywhere. In addition, you can not only take advantage of the leisure time, such as waiting for the promised person, but also can enjoy the karaoke / music game anytime, anywhere has the effect of relieving stress, improve quickness and emotion.

In addition, the present invention can sing in a chorus of several people in the virtual environment, as in the virtual environment, as in the karaoke of the real world, and makes it easy for ordinary people who are not skillfully dealing with real instruments to play music, You can play your own orchestra as if you were playing your own band by playing your own instrument at the same time as other virtual users in a virtual environment, without the need for a common space with expensive instruments and studios. It works.
