Further, for example, when “Aim for time” is selected, course menus such as “beginner”, “intermediate”, “advanced”, etc. are displayed on the screen of the user PC 2 as menu items in the fourth layer.

  When one menu item is selected from the menu items in the fourth hierarchy, a training course uniquely corresponding to the menu item is determined by the control unit 1 of the music distribution server 1. For example, when “Marathon race entry” to “Honolulu Marathon” to “Aim for time” to “Beginner” is selected, “Training course A” is determined. Similarly, when “intermediate” is selected, “training course B” is determined. Similarly, when “advanced” is selected, “training course C” is determined.

  The storage unit 12 of the music distribution server 1 stores menu data that defines the menu configuration. The storage unit 12 stores course information for each final training course. In this course information, all steps of the training course are defined, and the specifications of the training are defined for each step. Specifically, for each step, the corresponding training period, jogging time (user running time) as an example of exercise time, jogging distance (user running distance), number of songs in the music body, initial tempo (music for jogging) The tempo of the first song in the data), the end tempo (the tempo of the last song in the jogging song data), and the like are defined. Here, the jogging time is a time indicating the performance time of the music data for jogging, excluding the performance time of warm-up music and cool-down music described later.

  FIG. 5 shows an example of the specification of jogging music data in each step of a certain training course. This training course starts from step 1 and basically increases in steps every month.

  The training period of step 1 is set to the first month. That is, Step 1 is intended for jogging from the start of this training course until one month has passed. The jogging time is set to 30 minutes, and the jogging distance is set to about 5 km. The initial tempo and the final tempo are both set to 160 BPM.

  These pieces of information indicate that in step 1, the performance time of the jogging music data excluding the warm-up music and the cool-down music is 30 minutes, and the tempo is constant at 160 BPM. Then, it is assumed that the user runs a distance of about 5 km when the user runs for 30 minutes at a pace corresponding to this tempo.

  Here, although the number of music pieces to be played is set to eight songs, this is only a guide, and the number of songs changes depending on the performance time of the selected music piece.

  In FIG. 5, the contents of the medley music in step 1, that is, the contents of the music body to be played are “XXX medley” (“XXX” is, for example, the name of an album or the name of an artist). Although this is also shown in other steps, this shows an example of the selected album, artist, or genre. Is not selected.

  Next, the training period of step 2 is set to the second month. In other words, Step 1 is intended for jogging from the start of this training course until one month has passed and one month has passed. The jogging time is set to 30 minutes, the jogging distance is set to about 5.5 km, and the number of songs is set to eight. The initial tempo is set to 160 BPM, and the final tempo is set to 165 BPM.

  These pieces of information indicate that in step 2, the performance time of the jogging music data excluding the warm-up music and the cool-down music is 30 minutes, and the tempo gradually increases from 160 BPM to 165 BPM. Then, it is assumed that the user runs a distance of about 5.5 km by running for 30 minutes at a pace corresponding to this tempo.

  In Step 2, the jogging distance is the same as that in Step 1, but it is assumed that the user runs a distance approximately 0.5 km longer than Step 1 as the tempo increases.

  Similarly, the training period of step 3 is set to the third month, the jogging time is set to 45 minutes, the jogging distance is set to about 8 km, and the number of songs is set to 12. The initial tempo and final tempo are both set to 165 BPM.

  The training period in step 4 is set to the fourth month, the jogging time is set to 45 minutes, the jogging distance is set to about 8.5 km, and the number of songs is set to 12. The initial tempo is set to 165 BPM, and the final tempo is set to 170 BPM.

  The training period in step 5 is set to the fifth month, the jogging time is set to 60 minutes, the jogging distance is set to about 11 km, and the number of songs is set to 16 songs. The initial tempo and the final tempo are both set to 170 BPM.

  The training period in step 6 is set to the sixth month, the jogging time is set to 60 minutes, the jogging distance is set to about 12 km, and the number of songs is set to 16 songs. The initial tempo is set to 170 BPM and the final tempo is set to 175 BPM.

  As shown in FIG. 6, jogging music in each step includes a jogging main part composed of a music main body, a prelude, a postlude, an inter-musical part, a guide voice, and a DJ voice, and a warm played before the jogging main part. It consists of an up song and a cool down song played after the main jogging.

  In the figure, (a), (b), (c), (d), (e), and (f) correspond to Step 1, Step 2, Step 3, Step 4, Step 5, and Step 6, respectively. is doing.

  A warm-up song is a song that is supposed to be played when warming up such as a preparatory exercise before the user starts jogging. For example, the tempo gradually increases and the user's mood gradually increases. A song that excites is selected.

  The cool-down song is a song that is supposed to be played when the user finishes jogging and then performs cooling-down to return the mind and body to calm. For example, the tempo gradually decreases and gradually settles down. The music with the atmosphere that suits you is selected.

  The music data of the warm-up music and the cool-down music are stored in the storage unit 12 in the MP3 format.

  As the warm-up music and the cool-down music, it is possible to use the same music throughout all the steps. For example, when the user PC 2 downloads music data for jogging from the music distribution server 1 for the first time, The jogging music data including all the music data of the warm-up music and the cool-down music is downloaded, but the music data for jogging only of the music data of the main jogging is downloaded at the second and subsequent downloads.

  In the second and subsequent downloads, a warm-up song and a cool-down song different from the first downloaded warm-up song and cool-down song may be downloaded according to the user's selection.

  Further, as shown in FIG. 6, the jogging distance, that is, the performance time of the jogging main part increases every two steps. On the other hand, the tempo of the jogging main part is constant from the start to the end of the performance in the odd steps and gradually increases in the even steps. In addition, the final tempo in each step matches the tempo in the next step.

  As the step goes up (the training period is in the future in time), the jogging ability of the user is considered to improve, so the jogging time and tempo increase accordingly. Moreover, although it is a standard, the number of songs increases as the steps go up. The jogging time and tempo are determined for each training course, and further for each step in the training course. Specifically, for example, the jogging time and tempo are determined by experts such as marathons. Based on the exercise theory, policy, etc. set for each training course in advance.

  FIG. 7 is a diagram showing a schematic configuration of a jogging main part of music data for jogging.

  As shown in FIG. 7, in the jogging main part of the jogging music data, the prelude is reproduced first, and then the first music body is reproduced. Then, after the inter-music part is reproduced, the second music body is reproduced. In the same manner, after all the music pieces are reproduced, the later performance is reproduced. In other words, the main part of jogging is the connection data between the songs of the prelude, the first song body data, the song connection data between the songs, the second song body data, the song connection data between the songs, the Nth song It is comprised by the control part 11 of the music distribution server 1 so that it may reproduce | regenerate in order of music main body data and the connection music between succeeding music.

  At this time, for example, in the case of step 1 of the training course shown in FIG. 5, the jogging main part is configured so that each piece of music data is played at a constant tempo of 160 BPM. For example, in the case of step 2, 160 BPM The music data is reproduced so that the tempo gradually increases from 1 to 165 BPM.

  The main part of the jogging is configured so that the audio data is reproduced while the inter-music connection data of the prelude, the inter-song and the follower is being reproduced. In addition, every time a specified time elapses after the performance of the main jogging starts (for example, 5 minutes, 10 minutes, 20 minutes, ...), the elapsed time at that time and the calorie consumption so far are given to the user. The main part of jogging is configured so that audio data to be notified is reproduced.

  Note that the final training course may be determined when the third layer menu item is selected, and the step of starting the training may be determined when the fourth layer menu item is selected. For example, when “beginner” is selected, step 1 of training course A is determined as the start step, and when “intermediate” is selected, step 3 of training course A is determined as the start step. When “advanced” is selected, step 5 of training course A may be determined as the start step.

Next, a method of creating the main part of jogging music data for jogging by the control unit 11 of the music distribution server 1 will be described with reference to FIGS.

  FIG. 8 is a diagram illustrating an example of a method for creating a jogging main part of music data for jogging. FIG. 9 is a diagram showing an example of a method for determining the tempo of each piece of music constituting the jogging main part of the jogging music data when the initial tempo and the end tempo are different.

[2.3.1 When the tempo is constant]
The example shown in FIG. 8 is an example in which all tune tempo 120 BPM music data is converted to 160 BPM tune data and a jogging main part with a jogging time of 30 minutes is created. 10 pieces of music body data are selected in this music selection order. In addition to the inter-music connection data of the prelude and the follower, the inter-music connection data includes 6 inter-music connections of the inter-music part a to the inter-f part f having different numbers of measures (the length of the music). Assume that data is available.

  The control unit 11 converts the music main body data and the inter-music connection data into music main body data and inter-music connection data at a tempo of 160 BPM, respectively. Here, the performance time of each music is the original 3/4 (120 BPM / 160 BPM).

  Then, the control unit 11 inserts the pre-music connection data at the beginning of the jogging main part, and inserts the subsequent music connection data at the end of the jogging main part. Moreover, the control part 11 inserts the music main body data of the music A to the music J in the order of this music between the connection data between the prelude songs and the connection data between the succeeding songs.

  The performance time of the main part of jogging at this point, that is, the total of the performance time of the prelude, the music A to the music J, and the follower is less than 30 minutes, which is the jogging time. The inter-song part a has 4 bars, the inter-song part b has 8 bars, the inter-song part c has 12 bars, and the inter-song part f has 24 bars. Then, by inserting inter-song connecting data having an appropriate length among the inter-song part a to inter-song part f, adjustment is made so that the final performance time of the main jogging part is 30 minutes. It is not necessary to prepare the main jogging so that the performance time is exactly the jogging time (in this case, just 30 minutes), and there may be some deviation.

  Inter-song inter-song data is the music used to connect each music body in a musically (hearingly) natural way by connecting the songs of each music body between the songs. It is data.

  Here, the music body data is created by synthesizing the jogging arrangement drum base WAV data 106 with the WAV data of the music body converted from the music body MIDI data 105 as described in FIG. At this time, jogging arrangement drum base WAV data 106 having a rhythm pattern matching the tone of the music body is selected.

  If the rhythm patterns of the music pieces constituting the jogging music data are all the same, if only the data of the same rhythm pattern is prepared as the inter-song linking data of the music pieces, Since the rhythm pattern does not change before and after connection, you can continue playing in a natural way. However, in the case where the rhythm pattern of the music body differs from song to song, with one pattern, the rhythm pattern changes abruptly before and after connection of each song, making it unnatural musically.

  Therefore, in the present embodiment, when there are two or more rhythm patterns of a plurality of music main bodies constituting the music data for jogging, in accordance with this, the connection data between the songs in the inter-music part of the plurality of rhythm patterns Prepare.

  For example, if the rhythm pattern of one music body is different from the rhythm pattern of the next music body, the performance starts with the same (or close) rhythm pattern as the music body at the part connected to the previous music body In the part connected to the next song body, the performance ends with the same (or close) rhythm pattern as the song body, and the rhythm pattern gradually changes as the performance progresses. Prepare a part.

  For example, when two patterns of X and Y are mixed as rhythm patterns of a plurality of music main bodies constituting the music data for jogging, the rhythm pattern is a constant X portion, a constant Y portion. Four parts are prepared for each of the inter-music part a to the inter-f part f (for example, of the inter-music part a), the inter-music part, the inter-music part changing from X to Y, and the inter-music part changing from Y to X. In this case, the rhythm pattern has an X constant music interval portion a1, a Y constant music interval portion a2, an inter song portion a3 that changes from X to Y, and an inter song portion a4 that changes from Y to X).

  The control unit 11 recognizes the rhythm pattern of the music body by referring to the music information of the music body data before and after the music between which the music part is inserted, and between the music of the music part which becomes the rhythm pattern corresponding to this Insert splice data.

  Note that the tune pattern data of the prelude inserted before the first song body of the jogging main part uses the same (or close) rhythm pattern data as that of the main part of the jogging main part. It is desirable to use rhythm pattern data that is the same as (or close to) the rhythm pattern of the music piece main body as inter-song continuation data to be inserted later.

[2.3.2 When the tempo increases]
When the tempo increases, that is, when the initial tempo is less than the final tempo, the playback position on the time axis from the start to the end of the jogging main part playback of the jogging song data (the playback at the beginning of the jogging main part) It is necessary to change the tempo of each piece of music data in accordance with the elapsed time since the start of. In general, assuming that the tempo f (t) at the elapsed time t from the start of playback at the beginning of the jogging main part increases at a constant rate of change, f (t) = (final tempo−initial tempo) / jogging time × t. Desired.

  The tempo of each musical piece can be obtained when the reproduction position of the intermediate part between the beginning and the end is just t. Here, assuming that the playback position of the intermediate part of the nth music body is t (n), t (n) = the performance time of the prelude + (the total of the performance time of the music body from 1 to n−1). + (Total performance time of inter-music parts inserted after the 1st to (n-1) th music main bodies) + (performance time of the nth music main body / 2).

  However, if the tempo is not determined, the performance time of the music body cannot be obtained, so the tempo cannot be obtained by the above formula. Therefore, the control unit 11 obtains a provisional performance time of the music body after temporarily setting a tempo that seems to be close to the tempo to be obtained. Then, a tempo is obtained from the provisional performance time, and an accurate performance time is calculated based on the tempo.

  Further, the tempo of the prelude, the inter-song portion, and the follower can be obtained by the same method as described above.

  FIG. 9 shows an example in which 10 pieces of music body data of songs A to J are selected in this order of selection at an initial tempo of 160 BPM and a final tempo of 165 BPM. In this example, the prelude is set to 160.0 BPM, and the performance time is from 0 minutes 08 seconds to 0 minutes 06 seconds. For song A, 160.2 BPM is set, and the performance time is from 3 minutes 48 seconds to 2 minutes 51.7 seconds. Further, 160.5 BPM is set for the inter-music part b inserted after the music A, and the performance time is from 0 minutes 16 seconds to 11.9 seconds. For music J, 164.8 BPM is set, and the performance time is from 2 minutes 25 seconds to 2 minutes 05.2 seconds. Finally, 165.0 BPM is set for the later performance, and the performance time is from 0 minutes 08 seconds to 0 minutes 05.8 seconds. Here, in FIG. 9, the performance time rounded off is shown.

  In the above description, the tempo of each song is obtained so that the tempo increases linearly, but the tempo may be obtained so that the tempo increases linearly.

  In the above description, the tempo is obtained based on the playback position of the middle part between the beginning and the end of the music. For example, the tempo is based on the playback position of the first part of the music, the last playback position, etc. You may ask for.

  The tempo determination method is not limited to the above-described method. For example, considering the unit of measure rather than the unit of music, it is easy to calculate the playback position of each measure of the main part of jogging, and the tempo and length (performance time) of each measure can be calculated. From the length of each bar, you can see how many bars the main part of jogging consists of. Then, the performance time corresponding to the number of measures is calculated by 120 PBM, and the music body data and the connection data between the music are selected so that the total performance time at 120 BPM becomes the calculated performance time. Then, the tempo of the music body data and the connection data between songs is set according to the playback position for each measure, the tempo of the music body data and the connection data between songs is converted for each measure, and the tempo is adjusted. And the connection data between songs is created. Here, since the music main body data and the inter-song connecting data in this embodiment are WAV data, the tempo is actually converted every performance time of one measure in 120 BPM.

[3. Music distribution server operation]
[3.1 Main processing]
Next, the operation of the music distribution server 1 will be described. First, the main process will be described with reference to FIG.

  FIG. 10 is a flowchart illustrating a processing example in the main processing of the control unit 11 of the music distribution server 1 according to the present embodiment.

  First, when the user PC 2 accesses the music distribution server 1 by a user operation, as shown in FIG. 10, the control unit 11 of the music distribution server 1 executes a login process (step S1). Specifically, the control unit 11 receives a user ID, a password, and the like from the user PC 2 and performs an authentication process to specify a user.

  Subsequently, the control part 11 performs a course selection process (step S2). Specifically, the control unit 11 transmits a predetermined course selection WEB page to the user PC 2 to cause the user to select a training course as described in FIG. 4, and information on the selected training course is stored in the user PC 2. Receive from.

  Next, the control unit 11 transmits a predetermined WEB page to the user PC 2, causes the user to input his / her weight and gender, and receives these pieces of information from the user PC 2 (step S3). This user's weight is used to calculate the user's calorie consumption during jogging, and gender is used to determine the final training course. Since there is a difference in athletic ability depending on gender, the content (specifically, jogging time and tempo) is slightly changed depending on gender even in the same training course.

  Next, the control unit 11 determines a final training course based on the training course information and gender information received from the user PC 2 (step S4).

  In step S2, if the identified user does not change the training course selected by the previous time, the processing of step S3 may be omitted, and the training course information may be acquired from the user training information.

  Next, the control unit 11 determines a step (step S5). Specifically, the control unit 11 first transmits a WEB page presenting recommended steps on the system side to the user PC 2. For example, when a new training course is selected this time, Step 1 is recommended, and when the previous training course is not changed, the current step and music data for jogging of the training course are downloaded first. An appropriate step is recommended depending on the number of days since the day. Here, when the user accepts the presented step by operating the user PC 2, a request to that effect is transmitted from the user PC 2 to the music distribution server 1, while the user changes the step. The request to that effect is transmitted from the user PC 2 to the music distribution server 1. And the control part 11 determines a step based on this request.

  Next, the control unit 11 acquires the jogging time, the initial tempo, and the end tempo corresponding to the determined training course and step from the course information, and sets them in a predetermined area on the RAM (step S6).

  Next, the control unit 11 determines the song data used for creating the jogging song data, the song connection data, and the performance order by executing the song used determination process described later (step S7).

  Next, the control unit 11 creates jogging music data (step S8). Specifically, the control unit 11 first obtains music body data and inter-music connection data described in the performance list created in the used music determination process from the parts WAV data database, and determines the determined training course and Audio data corresponding to the step is acquired from the part WAV data database. At this time, the connection data between the pieces of music is acquired according to the rhythm pattern of the music main body data connected before that and the rhythm pattern of the music main body data connected thereafter. Next, the control unit 11 converts the acquired music main body data and inter-music connection data into music main body data and inter-music connection data of the set tempo, respectively. Next, the control unit 11 connects the music body data and the music connection data having the converted tempo in the order described in the performance list, and creates the WAV data of the jogging main part. Next, the control unit 11 causes the encoder unit 14 to convert the format of the main part of jogging to the MP3 format, and creates jogging music data. Then, the control unit 11 stores the created jogging music data in the storage unit 12 in association with the identified user.

  Next, the control unit 11 refers to the training information of the identified user, and determines whether or not the distribution of the jogging music data to this user is the first (step S9). That is, the control unit 11 determines whether or not the warm-up music and the cool-down music are stored in the user PC 2 because the music data for jogging has been previously downloaded to the user PC 2. At this time, if the distribution of the jogging music data to the specified user is not the first time (step S9: NO), the control unit 11 proceeds to step S11.

  On the other hand, when the distribution of the jogging music data to the specified user is the first (step S9: YES), the control unit 11 inserts the music data of the warm-up music at the head of the created jogging music data. Then, the music data of the cool down music is inserted at the end of the created jogging music data (step S10), and the process proceeds to step S11.

  And the control part 11 transmits the produced music data for jogging to user PC2 (step S11), and complete | finishes a main process.

  If the data size of the created jogging music data is large, the time required for transmission, that is, the download time becomes long, and if the session is disconnected during the download, it must be downloaded again. Inconvenient. Therefore, in such a case, the control unit 11 may create the jogging music data by dividing it every predetermined performance time (for example, every 30 minutes) and sequentially transmitting it to the user PC 2.

[3.2 Used music determination process]
Next, the music use determination process will be described with reference to FIG.

  FIG. 11 is a flowchart illustrating a processing example in the used music determination process of the control unit 11 of the music distribution server 1 according to the present embodiment.

  When the use song determination process is started, as shown in FIG. 11, the control unit 11 initializes the performance list (step S51), and sets the number of performance songs S to 0 (step 52).

  Next, the control unit 11 sets a prelude at the beginning of the performance list (step S53), and sets a prelude at the end of the performance list (step S54).

  Next, the control unit 11 sets an initial tempo as the tempo of the prelude, and calculates the performance time of the prelude based on this tempo (step S55).

  Next, the control unit 11 sets the final tempo as the tempo of the subsequent performance, and calculates the performance time of the subsequent performance based on this tempo (step S55).

  If the initial tempo is different from the final tempo, the tempo should be determined as described with reference to FIG. 9 in 2.3.2 above. When the performance time of a performance is short, the error can be ignored, so the initial tempo and final tempo are simply set.

  Next, the control unit 11 sets the total value of the calculated performance time of the prelude and the performance time of the subsequent performance as the total performance time (step S57).

  Next, the control unit 11 determines whether or not the initial tempo and the end tempo match (step S58). At this time, if the initial tempo and the end tempo match (step S58: YES), the control unit 11 executes the music determination main process 1 described later, and if the initial tempo and the end tempo do not match. (Step S58: NO), the music determination main process 2 described later is executed.

  And the control part 11 will complete | finish a use music determination process, after finishing the music determination main process 1 or the music determination main process 2. FIG.

[3.3 Music Determination Main Process 1]
Next, the music determination main process 1 will be described with reference to FIGS.

  FIG.12 and FIG.13 is a flowchart which shows the process example in the music determination main process 1 of the control part 11 of the music distribution server 1 which concerns on this embodiment.

  When the music determination main process 1 is started, as shown in FIG. 12, the control unit 11 sets an initial tempo as a use tempo that is commonly used for all music data used (step S101).

  Next, the control unit 11 performs a music selection process (step S102). Specifically, the control unit 11 first refers to the history information of the identified user, the album, artist or genre (hereinafter simply referred to as “album etc.”) selected by the user up to the previous time, and the album WEB page that presents a list of music included in the user PC 2 is transmitted to the user PC 2. Here, when the user selects a song from the list by operating the user PC 2 without changing the presented album or the like to another album or the like, a song selection request for the song (music designation information) Is transmitted from the user PC 2 to the music distribution server 1.

  On the other hand, when the user changes the presented album or the like to another album or the like, an album selection request (an example of album designation information) such as the selected album is transmitted from the user PC 2 to the music distribution server 1. In response to this, the control unit 11 transmits to the user PC 2 WEB page data that presents a list of albums or a search menu of albums. When the user selects an album or the like and selects a desired song from a plurality of songs included in the album or the like, a song selection request (an example of song designation information) for the song is sent from the user PC 2 to the song distribution server 1. Sent to.

  By receiving this selection request, the control unit 11 specifies and selects the music data of the (S + 1) th song.

  In addition, after the album or the like is selected at the time of selecting the first song, when the user selects, for example, “Random selection”, the control unit 11 side selects a plurality of songs included in the selected album or the like. A predetermined music piece may be automatically selected in the order of performance, or a music piece may be selected at random.

  Next, the control unit 11 sets the use tempo as the tempo of the selected music (hereinafter referred to as “selected music”), and calculates the performance time of the selected music at this tempo (step S103).

  Next, the control unit 11 determines whether or not jogging time− (total performance time + performance time of selected music) is greater than jogging time × 0.05 (step S104). For example, when the jogging time is 30 minutes, the control unit 11 determines whether or not 30 minutes− (total performance time + performance time of the selected music piece) is greater than 1 minute 30 seconds. At this time, when the jogging time− (total performance time + performance time of the selected music piece) is equal to or less than the jogging time × 0.05 (step S104: NO), the control unit 11 proceeds to step S102.

  Jogging time-(total performance time + performance time of the selected music), that is, if the remaining time excluding the total performance time including the performance time of the current selected music is too short, the connection data between each music body In such a case, the control unit 11 returns to step S102 and allows the user to select another music piece because the total performance time may greatly exceed the jogging time. .

  On the other hand, when the jogging time− (total performance time + performance time of the selected musical piece) is greater than jogging time × 0.05 (step S104: YES), the control unit 11 adds 1 to the number of musical pieces S to be played. The value is set to the number S of performance songs (step S105).

  Next, the control unit 11 sets the selected music piece as the S music piece in the performance list (step S106), and adds the performance time of the selected music piece to the current total performance time, thereby calculating the total performance time again (step S107). ).

  Next, the control unit 11 determines whether or not jogging time−total performance time is less than (jogging time × 0.05) +3 minutes (step S108). For example, when the jogging time is 30 minutes, the control unit 11 determines whether or not 30 minutes-total performance time is less than 4 minutes 30 seconds. At this time, when the jogging time-total performance time is (jogging time × 0.05) +3 minutes or more (step S108: NO), the control unit 11 proceeds to step S102.

  That is, when the jogging time-total performance time, that is, the remaining time is equal to or longer than the predetermined time, there is still room for adding the music body, so the control unit 11 proceeds to step S102 and proceeds to step S102. Is selected by the user.

  On the other hand, when the jogging time-the total performance time is less than (jogging time × 0.05) +3 minutes (step S108: YES), the control unit 11 performs the inter-music parts a to f as shown in FIG. The tempo to be used is set as the tempo, and the inter-song portions a to f based on this tempo are calculated (step S109).

  Next, the control unit 11 determines whether or not the number of performance songs S is 1 (step S110). At this time, if the number of performance songs S is not 1 (step S110: NO), the control unit 11 then calculates (jogging time-total performance time) / (S-1) as the performance time of the inter-music part e. It is determined whether it is longer (step S111). At this time, if (jogging time-total performance time) / (S-1) is longer than the performance time of the inter-music part e (step S111: YES), the control unit 11 determines the S-th music body of the performance list. The inter-music part f is inserted immediately before (step S112), and the process proceeds to step S122.

  On the other hand, when (jogging time-total performance time) / (S-1) is less than or equal to the performance time of the inter-music part e (step S111: NO), the control unit 11 then (jogging time-total performance time). It is determined whether (time) / (S-1) is longer than the performance time of the inter-music part d (step S113). At this time, if (jogging time-total performance time) / (S-1) is longer than the performance time of the inter-music part d (step S113: YES), the control unit 11 determines the music body of the S-th song in the performance list. The inter-music part e is inserted immediately before (step S114), and the process proceeds to step S122.

  On the other hand, when (jogging time-total performance time) / (S-1) is equal to or less than the performance time of the inter-music part d (step S113: NO), the control unit 11 then (jogging time-total performance time). It is determined whether (time) / (S-1) is longer than the performance time of the inter-music part c (step S115). At this time, when (jogging time-total performance time) / (S-1) is longer than the performance time of the music piece section c (step S115: YES), the control unit 11 determines the S-th music body of the performance list. The inter-song part d is inserted immediately before (step S116), and the process proceeds to step S122.

  On the other hand, when (jogging time-total performance time) / (S-1) is less than or equal to the performance time of the inter-music portion c (step S115: NO), the control unit 11 then (jogging time-total performance time). It is determined whether or not (time) / (S-1) is longer than the performance time of the inter-music part b (step S117). At this time, if (jogging time-total performance time) / (S-1) is longer than the performance time of the music piece part b (step S117: YES), the control unit 11 determines the S-th music body of the performance list. The inter-music part c is inserted immediately before (step S118), and the process proceeds to step S122.

  On the other hand, when (jogging time-total performance time) / (S-1) is less than or equal to the performance time of the inter-music part b (step S117: NO), the control unit 11 then (jogging time-total performance time). It is determined whether (time) / (S-1) is longer than the performance time of the inter-music part a (step S119). At this time, if (jogging time-total performance time) / (S-1) is longer than the performance time of the music piece part a (step S119: YES), the control unit 11 performs the music main body of the Sth song in the performance list. The inter-music part b is inserted immediately before (step S120), and the process proceeds to step S122.

  On the other hand, if (jogging time-total performance time) / (S-1) is equal to or less than the performance time of the music piece a (step S117: NO), the control unit 11 determines the S-th music body of the performance list. The inter-song part a is inserted immediately before (step S121), and the process proceeds to step S122.

  When any of the inter-song portions a to f is inserted immediately before the S-th song body, the control unit 11 sets the value obtained by subtracting 1 from the number of performance songs S as the number of performance songs S (step S122).

  Next, the control unit 11 calculates the total performance time again by adding the performance time of the inserted inter-music part to the current total performance time (step S123), and proceeds to step S110.

  And the control part 11 repeats the process of step S111-S123 for the number of performance music S-1 times, and when the performance music number S becomes 1 in step S110 (step S110: YES), the music determination main process 1 is complete | finished. Let

  In the processing of steps S111 to S123, the control unit 11 determines (jogging time−total performance time) / (S−1), that is, the remaining time obtained by subtracting the total performance time from the jogging time By comparing the value divided by (in other words, the average performance time of the inter-music part not yet inserted) with the performance time of the inter-music parts a to f, the optimal inter-music part is inserted and finally The total performance time is adjusted to be close to the jogging time.

  On the basis of the music data of the music main body and the music piece selected in the music determination main process 1 and the set tempo, music data for jogging is created in the process of step S8 shown in FIG. Then, when the portable music player 3 reproduces the created jogging music data, the music sound is output at a constant tempo.

[3.3 Music Determination Main Process 2]
Next, the music determination main process 2 will be described with reference to FIGS. 14 and 15.

  14 and 15 are flowcharts showing a processing example in the music determination main process 2 of the control unit 11 of the music distribution server 1 according to this embodiment. In FIG. 14 and FIG. The same code | symbol is attached | subjected.

  When the music determination main process 2 is started, as shown in FIG. 14, the control unit 11 sets an initial tempo as the current tempo used when each music body is selected (step S151).

  Next, when executing the music selection process (step S102), the control unit 11 sets the tempo of the selected music based on the method described in 2.3.2 above. Specifically, the control unit 11 first calculates a provisional performance time when the tempo of the selected song is the current tempo (step S152).

  Next, the control unit 11 calculates the playback position of the intermediate portion between the beginning and the end of the selected song, assuming that the performance time of the selected song is a provisional performance time (step S153). At this time, since the inter-music part inserted between the music of each music body and its tempo are determined in a later process, at this time, between each music played before the S + 1-th music body I don't know how long the club played Therefore, for example, the control unit 11 selects the inter-music part c that is an average performance time among the inter-music parts a to f, and the inter-music part when the tempo of the inter-music part c is the initial tempo. The provisional performance time of c is calculated, and this is provisionally set as the performance time of each music piece played before the S + 1-th music body. In this way, the control unit 11 calculates the playback position of the intermediate portion between the first and last portions of the selected song based on the performance time of the prelude, the performance time of the music body of the 1st to Sth songs, the provisional performance time of the inter-music part, and the like. It is.

  Then, the control unit 11 calculates the tempo corresponding to the playback position of the intermediate portion between the first and last of the selected music piece, sets this tempo as the tempo of the selected music piece, and calculates the performance time of the selected music piece at this tempo. (Step S154).

  Thereafter, the control unit 11 determines whether or not jogging time− (total performance time + performance time of selected music) is greater than jogging time × 0.05 (step S104). (S104: NO) The process proceeds to step S102, and if it is larger (step S104: YES), 1 is added to the number of performance songs S (step S105).

  Next, the control unit 11 sets the selected song as the S song in the performance list (step S106), adds the performance time of the selected song to the current total performance time, and recalculates the total performance time (step S107). .

  Next, the control unit 11 sets the tempo of the selected song as the current tempo (step S156).

  Next, the control unit 11 determines whether or not jogging time−total performance time is less than (jogging time × 0.05) +3 minutes (step S108), and (jogging time × 0.05) +3 minutes or more. If there is (step S108: NO), the process proceeds to step S102. If (jogging time × 0.05) + less than 3 minutes (step S108: YES), the process proceeds to step S110.

  As shown in FIG. 15, when the process proceeds to step S110, the control unit 11 determines whether or not the number of performance songs S is 1, and if the number of performance songs S is not 1 (step S110: NO). Based on the method described in 2.3.2 above, the tempo of the inter-music portion inserted immediately before the S-music main body is set.
