Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for providing information on music in response to a request from a user using a communication line (Internet), and more particularly to a performance support used when playing a keyboard instrument. The present invention relates to a system, a performance support method, and a technique effective when applied to a recording medium.

[0002]

2. Description of the Related Art In playing a keyboard instrument, a player does not always operate a specific key on the keyboard with the same finger. However, when performing a specific song, a player follows an arrangement of a plurality of notes. When a key is depressed, there is a regularity in finger operation when playing the key. Here, the finger operation when playing the key is called fingering or fingering operation, and the fingering number and the finger (hand) indicating the finger pressing the key
Is defined as fingering information including a fingering direction indicating the direction (right or left) in which to move, and a fingering image indicating an operation of a finger pressing a key as an image.

In particular, beginners who have just started learning keyboard instruments often practice using a musical score in which fingering numbers are arranged corresponding to notes, and fingering numbers are assigned to all notes constituting the score. Is desirably arranged. Therefore, a musical score on which a fingering number is described corresponding to each note constituting the musical score is commercially available.

Further, in order to assist a beginner to easily learn musical instrument performance, specific music data is read from a memory storing a plurality of music data, and a key to be pressed is emitted based on the music data. There is also provided a keyboard instrument provided with a key-indicating illuminant for each key. Further, there is also a keyboard musical instrument having a key pressing instruction function provided with a display device such as a liquid crystal for displaying a key to be pressed based on the music data.

[0005]

However, in a keyboard instrument having the above-described key-depressing instruction function, key-depression information indicating which key is to be pressed is stored in a memory in advance together with musical score information for automatically playing a tune. The key press instruction information is merely given to the player by causing the keys to be pressed to emit light sequentially in accordance with the automatic performance. That is, even though a beginner can depress a key by relying on a light-emitting indicator that emits light in accordance with an automatic performance or performance information displayed on a display device, he cannot learn how to use a finger correctly.

[0006] In many cases, a fingering number is described only at a key point of a melody line of a music (for example, the first note of a phrase) in a commercially available musical score, and a fingering number is used for accompaniment. In most cases, it is not described. If you are an intermediate level, if you know the fingering information for the first note of the phrase, you may be able to guide the following fingering operation yourself, but beginners who are self-study It is thought that they are confused by fingering judgment. As a result, beginners who are self-taught become nervous about playing musical instruments, and their motivation for self-study is likely to decrease, resulting in a problem that they will not last long.

On the other hand, a beginner who is teaching a musical instrument to an instructor can check with the instructor on the spot where he or she is confused about fingering. The learning effect is high. However, instructors do not always pay attention to how to carry their fingers when playing a song, so it may be difficult for beginners to respond immediately even if they are partially asked for finger operation. Many. In such a case, the instructor performs a part of the music, checks the fingering operation of the part one by one, and then enters a fingering number corresponding to the note on the score. However, performing such an operation for the entire song requires a great deal of time and effort, and often places a burden on the instructor.

Accordingly, an object of the present invention is to provide a performance support system, a performance support method, and a recording medium capable of providing a user with fingering information of the music by designating the music to be played by a user (beginner). And

[0009]

In order to achieve the above object, a performance support system according to the present invention comprises a service center for providing information for supporting learning of musical instrument performance and a user terminal device connected via a communication line. A performance support system, wherein the service center includes order data including information on music transmitted from the user terminal device and information specifying a method of preparing fingering information for teaching finger movements accompanying performance. Receiving means, fingering information preparing means for preparing fingering information based on the information about the music, and means for delivering the fingering information prepared by the fingering information preparing means to the user terminal device, Was provided.

[0010] Thus, the user can easily prepare fingering information of the music to be played via the communication line, so that the user's willingness to play due to fingering is not reduced, and the musical instrument performance is improved. Can be efficiently supported. In addition, since the instructor does not need to perform the work for obtaining the fingering number for the beginner, the time and labor for the instructor can be effectively used.

The information on the music transmitted from the user terminal device to the service center may include a music title, a music identification code assigned to each music, or a music score including musical notes, rests, and other music symbols. The information may be at least one of the information and the musical sound information of the music. Thus, the user can order fingering information of a song to be played without knowing the song name of the song. For example, the name of a song or the like flowing in a commercial may not be known. In such a case, if the song is actually dubbed and the song is designated by the tone information, the fingering information is obtained based on the tone information. Generated and provided.

Further, the fingering information preparing means can generate or obtain fingering information by a plurality of methods, and the user can select a method of preparing fingering information from the plurality of methods presented from the service center. Make a choice. More specifically, the fingering information preparation means detects each finger or rest by analyzing the electrical or optical detection of the fingering operation when the performance instructor performs the model performance, analyzing the time-series transition of the music. The fingering information is prepared either by using a fingering algorithm for calculating optimal fingering information corresponding to the above, or by extracting from a database storing fingering information created for each song for a plurality of songs. Thus, the service center can provide fingering information of any music. For example, most CDs
The music information of the music that is commercially available is stored in a storage device as a database, so that it can be retrieved and provided from the database. If so, fingering information can be provided by a fingering algorithm device. In addition, when the user wants not only the fingering information but also a fingering operation during the actual performance as a moving image, the performance instructor captures the information desired by the user by photographing the fingering operation when performing the model performance. Can be provided.

Further, fingering information can be obtained from a detection signal of a contact sensor or a non-contact sensor for detecting the operation of a finger and a keyboard. Alternatively, fingering information can be obtained from image information captured by a capturing device.

Further, the service center includes a method for generating fingering information specified by the user at the time of order and a fee calculating means for calculating a fee according to the content of the service, and distributes the fingering information to the user terminal device. At this time, it may be configured such that the commission information calculated by the commission calculating means is added and distributed.

[0015] Further, there is provided a music instructor terminal device connected via a communication line, and information obtained by electrically or optically detecting a fingering operation in the model performance performed by the music instructor is provided by the music instructor. It may be configured to be transmitted from the terminal device to the service center.

Next, in the service center, a subroutine of fingering information generation processing is executed corresponding to the content requested by the user in step S1 (step S2).

Next, the user confirms with the user whether the information content provided by the service center is sufficient based on the fingering information generation processing, and if "OK" (approval), a series of processing ends.
If it is "NG" (denial), the process returns to the service preparation process (step S1), and the input is requested again.

The preparation process of the performance support service performed in step S1 in FIG. 4 will be described with reference to the flowcharts shown in FIGS.

First, the user accesses the homepage of the performance support service provided by the service center using the user terminal device, and displays a request information input screen on the terminal device. Then, "Request fingering information generation" is selected from the performance support service menu (step S10).
0).

In step S100, "Request for fingering information generation"
Is selected, a screen for designating the requested song is displayed, and the user inputs song information of desired fingering information (step S200). On the other hand, if the “fingering information generation request” is not selected, the process for providing fingering information of the present system is not executed. Here, the user inputs at least one of song name or song code, score information of the song, and tone information as the song information. Note that the musical score information and the musical sound information can be transmitted in a file format that can be decoded by using a dedicated application at the service center.

Next, after designating the requested music in step S200, the user specifies a method of preparing fingering information of the requested music (step S300). In the present embodiment,
A method for retrieving fingering information stored in advance in a management music database, a method for generating fingering information from musical score information by a performance information analyzer, and a method for electrically or optically performing fingering operations when a performance instructor performs a model performance The fingering information can be prepared by any of the methods of detecting and extracting the fingering information, and the desired fingering information can be provided to the user.

Next, the user designates a method of delivering fingering information from, for example, a fingering number alone, a fingering image, a score with a fingering number, or the like, and a series of service request preparation processing ends. (Step S400).

FIGS. 6 and 7 are flowcharts showing the processing procedure performed by the service center in response to the designation of the requested music in the user terminal device (step S200 in FIG. 5). Here, the processing corresponding to the designation of the requested music is specifically processing for checking whether the fingering information of the music requested by the user can be provided, and this can be determined based on the presence / absence of musical score information of the requested music. In other words, the performance support system of the present embodiment can always generate fingering information of a requested song if there is music information of the song.

First, a specific processing flow when the user inputs music information as "music name / music code" in step S200 of FIG. 5 will be described. When the user inputs song information, it is determined that the input song information is specified by a song name / song code (step S201), and step S2 is performed.
At 03, a song title or song code of the song requested by the user is searched from the management song database stored in the storage device 11 (step S203). Then, in step S203, when a song that matches the song name or song code of the song requested by the user is extracted, in step S211 in FIG. 7, the user's requested song is registered in the management song database with the song title or song code. Is determined to be
In step S233, the musical score information stored for each song in the management song database is transferred to the work memory M3. In this case, the fingering information of the music requested by the user is also recorded in the recording device, and the fingering information desired by the user can be prepared instantaneously.

On the other hand, if a song that matches the song name or song code of the song requested by the user is not extracted from the management song database in step S203, the song requested by the user is replaced by the song title or song code in step S211 in FIG. It is determined that it is not registered in the management music database. In this case, the fingering information cannot be provided because there is no music information of the music requested by the user. Then, the process shifts to step S212 to store a message such as "The requested song has not been registered. Please send score information or tone information" to the work memory M1 and send the message to the user to transmit the score information or Instructs to transmit music information.

Next, a specific processing flow when the user inputs music information as "music score information" in step S200 of FIG. 5 will be described with reference to FIGS. Step S in FIG.
When the user inputs song information at 200, it is determined that the input song information is not specified by a song title or a song code, and the process proceeds to step S202 (step S20).
1). Then, in step S202, it is determined that the music information is input as the musical score information, and the musical score information of the music requested by the user is searched from the management music database stored in the storage device 11 (step S205). Here, if the song requested by the user is extracted from the management song database, the fingering information corresponding to the score information is also recorded in the recording device, and the fingering information of the song requested by the user is instantaneously provided. can do.

On the other hand, if the music requested by the user is not extracted from the management music database, the fingering information is generated based on the musical score information transmitted from the user using the performance information analyzer.

That is, in the preparation stage, step S205
After the search for the musical score information is performed, the process proceeds to step S233 in FIG. 7 and the musical score information is transferred to the work memory M3.

Next, a specific processing flow when the user inputs music information as "musical sound information" in step S200 in FIG. 5 will be described with reference to FIGS. Step 2 of FIG.
When the user inputs song information at 00, it is first determined that the input song information is not specified by a song title or song code, and the process proceeds to step S202 (step S20).
1). Further, in step S202, it is determined that the input music information is not specified in the music score information, and step S202 is performed.
The process proceeds to 204. Then, in step S204, it is determined that the music information is input as the musical sound information, and the storage device 1
It is searched in the management music database stored in No. 1 for a management music whose musical information matches the request music input by the user (step S206). When the song requested by the user is extracted from the management song database in step S206, the process proceeds to step S214 in FIG.
Here, it is determined that the music information of the requested music is registered in the management music database, and the process shifts to step S213 to transfer the music information stored for each music in the management music database to the work memory M3.

On the other hand, in step S206, if no music whose musical sound information matches the music is extracted from the management music database,
The flow shifts to step S214 in FIG. 7, where it is determined that the music information of the requested music is not registered in the management music database, and the flow shifts to step S215, where the musical score information is obtained based on the music information using the performance analyzer. Generated. Then, the generated musical score information is transferred to the work memory M3 (step S216).

In this manner, the preparation process is performed according to the provision form of the song information (song name / song code or score information or tone information) input by the user, and the score information of the requested song is prepared in the work memory. Is done.

FIG. 8 is a flowchart showing a procedure of a preparation process performed in the service center corresponding to a method for preparing fingering information specified by the user terminal device (step S300 in FIG. 5).

First, the case where the user designates "request to performance instructor" in step S300 of FIG. 5 will be described. When the user specifies a method for preparing fingering information in step S300 in FIG. 5, the process proceeds to step 301 in FIG. 8, and the method for preparing fingering information specified by the user is "request to performance instructor". It is determined, and in step S303, "performance instructor" is set as a method for preparing fingering information.

The method of generating fingering information by requesting the performance instructor is suitable when a fingering operation is desired as a moving image, and the user can feel the performance of the performance instructor while feeling human. The ability to imitate fingering operation gives a sense of trust and security. Further, the performance instructor need only record the performance operation with a simple photographing device while using the conventional acoustic keyboard instrument as it is. The performance instructor simply transmits the performance image of the model performance recorded in this way to the service center, and based on these, fingering information such as a fingering number and a fingering image is automatically generated, and communication is performed. Since the performance information is promptly provided to the user via the line (the Internet), it is possible to eliminate the double labor of manually writing the fingering number on the musical score while performing as in the related art.

Next, the case where the user designates "use fingering algorithm" in step S300 of FIG. 5 will be described. When the user specifies a method for preparing fingering information in step S300 in FIG. 5, the process proceeds to step S301 in FIG. 8, and the method for preparing fingering information specified by the user is not "request to performance instructor". Determined, step S30
It moves to 2. Then, it is determined in step S302 that the fingering information generation method specified by the user is “use fingering algorithm”, and “use fingering algorithm” is set as a fingering information preparation method in step S305. .

In the method of generating fingering information by the fingering algorithm, the music requested by the user is automatically analyzed to generate the fingering information. Request). In addition, the generated fingering pattern is always logically consistent, uniform and stable, and does not reflect variations in fingering operation due to the habit of the music instructor or weaknesses .

Next, the case where the user designates "database search" in step S300 of FIG. 5 will be described. When the user designates a method for preparing fingering information in step S300 in FIG. 5, steps S301 and S302 in FIG.
Are both determined to be "NO", and the routine goes to Step S304. Then, in step S304, it is determined that the method for preparing fingering information specified by the user is "search from database", and "database search" is set as the method for preparing fingering information in step S306.

In the method of preparing fingering information by retrieving from the database, if the user's requested music is registered in the management music database, the user can acquire the fingering information in a short time. Furthermore, since the fingering information of the tunes managed in the database is registered in advance by a performance expert, there is a sense of security and the use fee is the lowest.

In the present embodiment, the method of preparing fingering information is “requesting a performance instructor”, “using a fingering algorithm”,
The user is designated from among three of "search from database". If the fingering information generation method is not specified from the three methods, that is, if "NO" in step S306, The request is not officially accepted. The user may select a method of generating fingering information according to his / her preference in consideration of a difference in a fee, processing time until information is provided, characteristics, and the like.

FIG. 9 is a flowchart showing a processing procedure performed by the service center in response to designation of the delivery format of fingering information made by the user terminal device (step S400 in FIG. 5). In the present embodiment, not only the fingering number information of the music requested by the user is provided, but also the score information with the fingering image information and the fingering number attached can be provided.

First, in step S401, it is determined whether the delivery format is "only fingering number", and if "YES", the process proceeds to step S401.
403 and the delivery format is No. Set to 1. In this case, a simple list of fingering numbers is delivered to the user as fingering information. On the other hand, if “NO”, the process moves to step S402.

In step S402, it is determined whether the delivery format is "score with fingering number attached", and if "YES", the delivery format is No. in step S405. Set to 2. In this case, not only the fingering number but also the musical score is provided together, and delivered in the form of a musical score with the fingering number attached to the note. On the other hand, if “NO”, the process moves to step S404.

In step S404, it is determined whether the delivery format is "finger image only". If "YES", step S4 is performed.
03 and the delivery format is No. Set to 3. Here, the fingering image represents the fingering number as an image. For example, the image of the "index finger" corresponds to the fingering number "2". FIG.
By using the fingering image database shown in (B), a list of fingering images corresponding to music can be easily created. It is also possible to provide a fingering image in which a performance operation is recorded as a moving image. On the other hand, if “NO”, the process moves to step S406.

In step S406, it is determined whether the delivery format is "score information with fingering image attached", and if "YES", the delivery format is No. in step S407. 4 is set. In this case, not only the fingering image but also the musical score is provided together and delivered in the form of a musical score to which the fingering image is attached corresponding to the musical note. Note that the score and the fingering image can be separately delivered. On the other hand, if “NO”, the process proceeds to step S40.
Move to 8.

In step S408, it is determined whether the delivery format is "score with fingering number and fingering image attached", and "YE
S ", the delivery format is set to No. 5 in step S409. In this case, usually, the one provided with the fingering number and the fingering image corresponding to the musical note of the musical score is provided. The fingering number and the fingering image can be separately delivered.

FIG. 10 is a flowchart specifically showing the operation procedure of the fingering information preparation process performed in the service center performed in step S2 in FIG.
When the request content is designated by the user terminal device according to FIG. 5, the processing of FIGS. 6 to 9 is performed in the service center, and then the processing operation shown in the flowchart of FIG. Information is prepared.

First, in step S501, it is determined whether or not a request from a user can be accepted. For example, if there is an input deficiency such as no specification of the delivery format in the specification of the request content, the request cannot be accepted and the process is terminated. In such a case, a request content input screen may be displayed to instruct the user to input again.

Next, when the contents of the request from the user are accepted in step S501, the method for preparing fingering information (specified in step S300 in FIG. 5) and the information delivery format (specified in step S400 in FIG. 5) are set. The billing amount is calculated according to the request, and the billing amount is transmitted to the user (step S50).
2). Then, if the user obtains consent from the billing amount transmitted to the user in step S502, the process proceeds to step S50.
Then, if the user's consent is not obtained, the processing is terminated (step S503). Normally, as for the method of preparing fingering information, the fee is higher for "requesting a performance instructor" than for "search from database" or "using fingering algorithm". The price is set higher when a plurality of pieces of information are ordered as a set.

Next, in step S504, the work memory M
1 if there is a message in the work memory M1, that is, if the user inputs song information by song name or song code but the requested song is not registered in the management song database of the service center ( In step S222 in FIG. 7, a message “Request music has not been registered. Please send score information or musical information” is sent to the user, and the process ends (step S505).

Next, in step S506, the method of preparing fingering information specified by the user is determined. If "database search", the process proceeds to step S800 in FIG. 12, and if "use fingering algorithm", the process proceeds to step S800. The flow shifts to S507, and if "request to the performance instructor", the flow shifts to step S700 in FIG.

First, the case where the method of generating fingering information by using “fingering algorithm” is selected will be described. In step S507, the musical score information transferred to the work memory M3 in step S213 or step S216 in FIG. 7 is read, and a fingering algorithm is applied to the musical score information read using the performance information analyzer. Information is generated.

Next, at step S508, whether the fingering image is included in the delivery format, that is, if the delivery format is No. 3-No. 5
Is determined, and if the fingering image is included in the delivery format, the process proceeds to step S509.
