Here, each of the plurality of types of rhythm units is a sound length based on one beat, and includes sound lengths corresponding to sixteenth notes, eighth notes, quarter notes, and half notes. When one beat is composed of triplets, the plurality of types of rhythm units may include 1/3 beat. The plurality of types of rhythm units are preferably shorter than the beat of the acquired music data. In the present embodiment, “sixteenth notes” or “eighth notes” can be selected as a plurality of types of rhythm units. For example, the note density of the song data is determined based on the acquired song data, and when the determined note density is equal to or higher than the density threshold, the rhythm corresponding to the sound length corresponding to the “16th note” When the unit (an example of the first rhythm unit) is selected and the density of the determined note is smaller than the density threshold, it corresponds to “eighth note” longer than the note length corresponding to “sixteenth note” The rhythm unit (an example of the second rhythm unit) corresponding to the sound length to be selected is selected as the rhythm unit. Also, for example, when the tempo of the song data is equal to or greater than a predetermined tempo threshold, a rhythm unit (an example of the first rhythm unit) corresponding to the sound length corresponding to “16th note” is selected, When the tempo of the song data is smaller than the tempo threshold, the rhythm unit (an example of the second rhythm unit) corresponding to the sound length corresponding to the “eighth note” longer than the sound length corresponding to the “16th note” ) Is selected as the rhythm unit.

The switching unit 96 switches the operation mode of the rhythm unit determining unit 97 between the first, second and third modes based on the operation of the setting operator 4. The rhythm unit determination unit 97 determines the rhythm unit to be “16th notes” when the density of the determined note is equal to or higher than the density threshold in the first operation mode, and is less than the density threshold. In this case, the rhythm unit is determined to be “eighth note”.

The rhythm unit determination unit 97 determines the rhythm unit as “16th notes” when the determined tempo is equal to or higher than the tempo threshold in the second operation mode, and when the rhythm unit is less than the tempo threshold. The rhythm unit is determined as “eighth note”. The rhythm unit determination unit 97 determines the rhythm unit to the selected sound length in the third operation mode. The rhythm unit determination unit 97 may change the rhythm unit in the middle of the song.

The reproduction start unit 98 starts the reproduction of the acquired music data based on the operation of the setting operator 4 and controls the start and stop of the timer 13. The display control unit 99 displays the display state of the four display units 72 in each display unit row 71 based on the time information of the timer 13, the acquired song data, and the determined rhythm unit. The unit 7 is controlled. In the present embodiment, the change of the display state means, for example, changing the light-off state to the light-on state or changing the light-on state to the light-off state.

Specifically, the display control unit 99 turns off all the display units 72 as an initial state before starting the reproduction of the music data. After the reproduction of the song data is started, the display control unit 99 turns on the display unit 72a of the display unit column 71 at a time point a predetermined time before the time point at which the key 21 corresponding to each display unit column 71 is to be operated. In the present embodiment, the predetermined time is three determined rhythm units (three rhythm units).

When the first rhythm unit has elapsed, the display control unit 99 turns off the display unit 72a and turns on the display unit 72b. When the next one rhythm unit has elapsed, the display control unit 99 turns off the display unit 72b and turns on the display unit 72c. When the next one rhythm unit further elapses, that is, when the key 21 is to be operated, the display control unit 99 turns off the display unit 72c and turns on the display unit 72d.

(4) Learning Process FIG. 6 is a flowchart showing the learning process performed by the learning control unit 9. The learning process of FIG. 6 is performed by the CPU 12 of FIG. 1 executing a learning program stored in the ROM 11 or the storage device 14. In the initial state, all the display units 72 are turned off.

First, the song data acquisition unit 91 acquires song data from the storage device 14 based on the operation of the setting operator 4 by the user (step S1). Next, the rhythm unit determination unit 97 determines the rhythm unit automatically or based on the selection by the user (step S2). Here, a practice portion of music data, a playback start position, a tempo, a tone color, a volume, and the like may be set.

Next, the display control unit 99 determines the lighting state of the display unit 72 before starting reproduction based on the music data (step S3). Moreover, the display control part 99 lights the specific display part 72 more than 0 based on the determined lighting state (step S4). Therefore, when there is no corresponding display unit 72, none of the display units 72 is lit. Subsequently, the display control unit 99 specifies the pitch after the next one rhythm unit (step S5).

Thereafter, the playback start unit 98 determines whether or not playback start is instructed (step S6). When the reproduction start is not instructed, the reproduction start unit 98 waits until the reproduction start is instructed. When the reproduction start is instructed, the reproduction start unit 98 activates the timer 13 (step S7).

Thereafter, the reproduction start unit 98 determines whether or not the reproduction end is instructed (step S8). If the end of playback is not instructed, the playback starter 98 updates the playback time of the song data (step S9).

Next, the display control unit 99 determines whether one rhythm unit has elapsed based on the time information of the timer 13 (step S10). If one rhythm unit has not elapsed, the display control unit 99 returns to the process of step S8. The processes in steps S8 to S10 are repeated until one rhythm unit elapses.

When one rhythm unit has elapsed, the display control unit 99 updates the lighting state of the display unit 72 based on the pitch specified most recently among the pitches specified in step S5 or step S13 described later. (Step S11). Moreover, the display control part 99 lights the specific display part 72 of 0 or more based on the determined lighting state (step S12). Similarly to step S4, when there is no corresponding display unit 72, none of the display units 72 is lit.

Next, the display control unit 99 specifies the pitch after the next one rhythm unit (step S13), and returns to the process of step S8. Until the end of reproduction is instructed, the processes in steps S8 to S13 are repeated. In step S8, when the end of playback is instructed, the playback start unit 98 stops the timer 13 (step S14) and ends the learning process.

(5) Effects In the learning device 1 according to the present embodiment, after the reproduction of the song data is started, the display of the corresponding display section row 71 is performed from the time before the key 21 is operated to the time when the key 21 is operated. The units 72a to 72d change in order for each rhythm unit. Thereby, the user can recognize in advance the key 21 to be operated while grasping the rhythm of the music by visually recognizing the change of the display parts 72a to 72d of the display part row 71. Therefore, the user can learn to play the song while grasping the sense of rhythm.

In particular, when one beat is composed of triplets, each display section row 71 preferably includes three stages or display sections 72 that are integral multiples thereof. In the present embodiment, each display section row 71 includes a four-stage display section 72. However, when one beat is composed of a triplet, the three-stage display section of the four-stage display section 72 is displayed. It is possible to use the unit 72 (72b, 72c, 72d) and not to use the display unit 72a farthest from the performance operator 2. That is, not all of the plurality of display units 72 are used, but the display states of only the

display units

72b, 72c, 72d that do not include the display unit 72a farthest from the performance operator 2 among the plurality of display units 72 are sequentially arranged. It can be changed.
