Description

[Technical field]

[0001] The present invention relates to a stringed instrument that assists the performer in playing. [Background technology]

[0002] There have been known practice guitars that are equipped with a function that displays on the fingerboard the position where to press the strings and the playing technique. Examples of this type of guitar include one that has a large number of light-emitting diodes (hereinafter referred to as "LEDs") arranged in a matrix on the neck and uses the light emitted by the LEDs to indicate the string position that should be operated (see Patent Document 1), and one that uses a liquid crystal display (hereinafter referred to as "LCD") or an electroluminescent display (hereinafter referred to as "ELD") as the fingerboard.

[0003] In such stringed instruments, fingering position marks are displayed on the fingerboard at positions where strings should actually be pressed in accordance with the music being played. The fingering position marks are displayed almost simultaneously with or just before the timing of the performance in the order of performance, allowing the performer to easily play by pressing the strings above the displayed fingering position marks.

[0004] However, if the fingering position mark is displayed at the timing when a performance should be made, the performer may not be able to respond immediately. For this reason, it has been considered to display the name of the next chord to be played on the fingerboard while playing. This chord name is not displayed close to the fingers pressing the strings, but on the body side, slightly away from the hand (see Patent Document 1). This is to prevent the displayed chord name from being hidden by the fingers playing. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2023-153677 A [Patent Document 2] Japanese Patent Application Publication No. 11-249651 [Patent Document 3] JP 2005-266728 A [Patent Document 4] Japanese Patent Application Publication No. 9-6331 Summary of the Invention [Problem to be solved by the invention]

[0006] As described above, by displaying the chord name with ample time to inform the performer of the next chord to be played, the performer can perform more smoothly. However, even if the name of the next chord to be played is displayed in advance, the chord name alone does not tell the performer which strings to press when playing that chord, so it is not very useful until the performer has memorized the relationship between the chord name and the fingering position. Also, the performer sometimes had trouble understanding the timing for playing the chords indicated by the displayed chord names.

[0007] An object of the present invention is to provide a stringed instrument that allows the player to confirm in advance, while playing, the fingering position of the next chord to be played as well as the fingering position to be currently played, thereby assisting in smoother playing. Another object of the present invention is to provide a stringed instrument in which the timing for switching sounds can be specified. [Means for solving the problem]

[0008] The first invention comprises a fingerboard made of a liquid crystal display or an electroluminescence display provided on the surface of the neck body, a plurality of frets arranged on the fingerboard at a predetermined interval from each other, and a display control unit that causes a first pressing position mark indicating the position at which to press a string corresponding to the chord to be played and a second pressing position mark indicating the position at which to press a string corresponding to the chord to be played after the chord to be played, on the fingerboard, the display control unit causes the first pressing position mark to be displayed at the position at which the string should be pressed, and also causes the second pressing position mark to be displayed in a predetermined second area that is located closer to the body than a first area in which the first pressing position mark is displayed during playing.

[0009] In a second invention, the display control unit sets one fret closer to the body than the first area as a reference fret, and sets an area away from the next position where the string should be pressed toward the body, equal to the number of fret-to-fret areas between adjacent frets between the reference fret and the 0th fret, as the second area.

[0010] In a third aspect of the present invention, the standard fret is the 12th fret.

[0011] In a fourth aspect of the invention, the fingering position marks are numbers indicating the names of the strings to be fingered.

[0012] The fifth invention comprises a fingerboard formed of a liquid crystal display or an electroluminescence display provided on the surface of the neck body, a plurality of frets arranged on the fingerboard at predetermined intervals, and a display control unit which causes fingerboard to display, in accordance with the chord to be played next, string pressing position marks indicating the positions at which strings should be pressed to play the chord, and also causes fingerboard to display performance timing marks indicating the timing at which the chord should be played, and the display control unit displays the performance timing marks in correspondence with frets corresponding to the number of beats from the current time to the timing at which the chord should be played, with the distance between adjacent frets being a preset number of beats, and moves the performance timing marks to the corresponding frets in accordance with the progress of performance from the current time, until the performance timing mark reaches the preset reference fret at the timing at which the chord should be played.

[0013] A sixth invention comprises a fingerboard made of a liquid crystal display or an electroluminescence display provided on the surface of a neck body, a plurality of frets arranged on the fingerboard at predetermined intervals, and a display control unit which causes fingerboard to display, in correspondence with the chord to be played next, string pressing position marks indicating the positions at which strings should be pressed to play the chord, and also causes fingerboard to display performance timing marks indicating the timing at which the chord should be played, and the display control unit displays the performance timing marks which change in correspondence with the number of beats until the timing at which the chord should be played, and when the timing at which the chord should be played has passed, displays, in place of the performance timing marks, a new performance timing mark which corresponds to the chord to be played after the chord and which changes in correspondence with the number of beats until the timing at which the chord should be played, in place of the performance timing marks.

[0014] In a seventh aspect of the invention, the display control unit causes a beat mark indicating the number of beats of the chord to be played next to be displayed on the fingerboard together with the performance timing mark, and when the timing for playing the chord corresponding to the performance timing mark has passed, causes a new beat mark indicating the number of beats of the chord to be played next to the chord to be played is displayed in place of the beat mark. Effect of the Invention

[0015] According to the first invention, the second fingering position mark corresponding to the next chord to be played is displayed in the second area, which is a predetermined distance away from the first area, which is the actual position to be pressed, on the body side, so that the second fingering position mark is not hidden by the performer's fingers pressing the strings while playing, and the performer knows the next chord to be played. Moreover, since the second fingering position mark shows the position of the fingers pressing the strings, the performer knows the shape of the fingers when playing the next chord, unlike when the chord name is simply displayed, and can imagine the next fingering shape before the first fingering position mark is displayed in the first area. This allows the performer to play more smoothly.

[0016] According to the second invention, the second pressing position mark corresponding to the next chord to be played is always displayed at a position a predetermined distance away from the actual pressing position of the next chord to be played. This allows the performer to imagine pressing the string by always shifting the successively displayed second pressing position marks by a predetermined distance toward the head, even if the actual pressing position changes from one piece to another depending on the piece of music, and thus allows the performer to more quickly press the first pressing position mark displayed at the actual pressing position.

[0017] According to the third invention, the second fingering position mark is always displayed at a position that is one octave off from the actual fingering position of the chord to be played next. The note at the position where the second fingering position mark is displayed is the same note as the note to be played next, but one octave higher, so the player can not only grasp the relative positions of each finger, but also understand the pitch at the same time.

[0018] According to the fourth invention, when a performer looks at the fingering position mark from diagonally above while playing, even if the fingering position mark is misaligned with the position of the string, the performer can accurately determine which string the fingering position mark corresponds to based on the number indicating the name of the string to be pressed.

[0019] According to the fifth aspect of the invention, the performer can know not only the fingering position but also the timing to move to the next chord from the performance timing mark. The performance timing mark informs the performer that the performance timing of the next chord is approaching by moving, so the performer can predict the timing in advance and perform smoothly.

[0020] According to the sixth aspect of the invention, the performer can know not only the fingering position but also the number of beats until the timing to move to the next chord by the performance timing marks. Therefore, the performer can predict the timing in advance and perform smoothly.

[0021] According to the seventh aspect of the present invention, the performer can know in advance the number of beats of the chord to be played next by the beat number mark. For example, when the number of beats is small, the performer can predict that he or she must move on to the next note immediately and play accordingly. [Brief description of the drawings]

[0023] [First embodiment] A first embodiment of the present invention will be described below. Fig. 1 is a schematic diagram of a guitar according to an embodiment, Fig. 2 is a perspective view of frets, Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1, and Fig. 4 is a block diagram of a control device according to an embodiment. Fig. 5 shows an example of first and second fingering position marks on a fingerboard, and Fig. 6 shows an example of performance timing marks.

[0024] As shown in Fig. 1, the guitar of this embodiment includes a body 1, a neck 2, and a head 3. As shown in the cross-sectional view of Fig. 3, the neck 2 includes a fingerboard 5 configured by attaching a liquid crystal display (hereinafter referred to as "LCD") to the surface of a neck body 4, and a fret member F attached to the neck body 4 so as to straddle the fingerboard 5.

[0025] As shown in FIG. 2, the fret member F is a ladder-shaped member in which two long connecting members 6 connect both ends of a number of frets f arranged at predetermined intervals on the fingerboard 5 along the neck body 4. Note that, from the side closest to the head 3, the frets f are represented as 0th fret f0, 1st fret f1, 2nd fret f2, ..., nth fret fn, but when there is no need to distinguish between positions, they are all referred to as fret f. Both ends fa of the fret f in the longitudinal direction are connected to connecting members 6 (see Figures 2 and 3).

[0026] In this type of fret member F, the connecting members 6 are arranged along both sides of the surface of the neck body 4, and as shown in Fig. 3, the frets f straddle the fingerboard 5, and a part of the connecting members 6 is embedded in the recesses 4a formed along both sides of the surface of the neck body 4. In the first embodiment, a small gap 7 is maintained between the frets f and the surface of the fingerboard 5, so that they are kept in a non-contact state.

[0027] Alternatively, each fret f may be U-shaped or bow-shaped, and both ends fa in the length direction may be fixed directly to the neck body 4 without using the connecting member 6. In this embodiment, each fret f is not in contact with the surface of the fingerboard 5 so that no pressure is applied to the LCD, but maintaining the non-contact state is not essential. For example, if a protective cover or the like is provided on the surface of the LCD to reduce the effect of pressure, the gap 7 may be omitted. Also, each fret f may be attached to the fingerboard 5 individually without using a fret member F that integrates multiple frets f.

[0028] As described above, with the fret member F provided on the neck 2, the first to sixth strings s1 to s6 are strung from the bridge 8 of the body 1 to the head 3 on the frets f. Also provided within the body 1 is a data processing box 10 for controlling the display of the fingerboard 5, which is made up of an LCD (see FIG. 1).

[0029] As shown in FIG. 4, the data processing box 10 includes a receiving unit 11 that receives control data synchronized with the output from the external terminal 9, and a display control unit 12 that controls the display of the LCD, which is the fingerboard 5, based on the control data received by the receiving unit 11. The external terminal 9 is, for example, a personal computer or a smartphone, and is equipped with a wireless communication function and a control data creation function for creating and outputting control data for displaying marks corresponding to a piece of music to be played on the guitar of this embodiment. When a piece of music is selected on a display screen or the like, the external terminal 9 starts outputting control data corresponding to the piece of music. Here, for example, the external terminal 9 creates control data based on guitar score data using the control data creation function. Also, for example, the control data creation function is realized by an application program on a personal computer or the like.

[0030] The control data for the fingerboard 5 is data for assisting in the performance of each piece of music, and is data for displaying on the fingerboard 5 a first fingering position mark 13 corresponding to the chord to be played at the present time, and a second fingering position mark 14 corresponding to the next chord to be played. The first fingering position mark 13 is a mark indicating the position where the string should be pressed, and is a number displayed in the area E1 of the fingerboard 5 corresponding to the string and fret to be pressed. This number corresponds to the number representing the string.

[0031] For example, when the first string s1 is pressed at the first fret f1, the number "1" indicating the first string is displayed in an area along the first string s1 between the zeroth fret f0 and the first fret f1 on the fingerboard 5 as the first pressing position mark 13. At this time, the number "1" is displayed so that its up-down direction is parallel to the first string s1. Similarly, "1" to "6" are displayed as the first pressing position mark 13 in the areas between each fret along the first string s1 to the sixth string s6, respectively.

[0032] FIG. 5 shows an example of a first fingering position mark 13 and a second fingering position mark 14 corresponding to a C chord. If the chord to be played at the moment is a C chord, the area E1 corresponds to the 2nd string s2 of the 1st fret f1, which is the position to be actually held down 1 "2" in the area E1, which corresponds to the 4th string s4 on the 2nd fret f2 2 "4" in the area E1, which corresponds to the 5th string s5 on the 3rd fret f3 3 The number "5" is displayed in the area E1 as the first fingering position mark 13. 1 ,E1 2 ,E1 3 is the first area E1 in which the first fingering position mark 13 is displayed.

[0033] On the other hand, the second fingering position mark 14 is a mark that indicates the chord that should be played next. For ease of explanation, the case where the chord that should be played next is also a C chord is shown here. The fingering position when actually playing a C chord is the position of the first fingering position mark 13 described above, but when the performer presses his / her fingers on this first fingering position mark 13, even if the second fingering position mark 14 for the next C chord to be played is displayed in the same position, it will be hidden by the performer's hand and will not be visible. In this embodiment, the second fingering position mark 14 is displayed in the second area E2, which is shifted toward the body 1 by a predetermined distance L from the first fingering position mark 13. Therefore, although the position where the second fingering position mark 14 is displayed is not the position where the string should actually be pressed, the relative position of the string to be pressed and the fingers will be the same as that of the first fingering position mark 13. This distance L is determined as follows.

[0034] For example, depending on the music piece to be played, the reference fret f is set at a position that is not included in the first area E1 that is often covered by the player's fingers. In FIG. 5, the 12th fret f12 is set as the reference fret and is marked with a triangle. The reason why the 12th fret f12 is set as the reference fret is that the 12th fret f12 is one octave higher than the 0th fret, and the area on the fingerboard 5 from the 12th fret f12 to the body 1 side is rarely used during the performance of the music piece and is not covered by the player's fingers during the performance. The number of fret-to-fret areas between adjacent frets included between the 12th fret f12 and the 0th fret f0, which are the reference frets, corresponds to the distance L.

[0035] That is, when the reference fret is the 12th fret f12, the second area E2 is a position that is a distance of 12 fret spaces away from the first area E1 toward the body 1. Therefore, when the next chord to be played is also a C chord, the second fingering position mark 14 corresponds to the position of the second string s2 of the 1st fret f1 to be played next, and the second fingering position mark 14 corresponds to the area E2 corresponding to the second string s2 of the 13th fret f13. 1Similarly, the display control unit 12 also displays the other second fingering position marks 14 in the second area E2, which is 12 fret spaces away from the first area E1 in which the corresponding first fingering position mark 13 is displayed, toward the body 1. For example, if the position of the string to be pressed for the next chord to be played is the position of the fifth string s5 at the 5th fret, the second fingering position mark 14 will be displayed in the area E2 corresponding to the fifth string s5 at the 17th fret. 1 will be displayed.

[0036] In accordance with the progress of the music piece, at the timing when the second stringing position mark 14 should be played, the display control unit 12 moves the second stringing position mark 14 to the first area E1 and displays it as the first stringing position mark 13. Then, in the second area E2, a new second stringing position mark 14 corresponding to the next chord to be played is displayed.

[0037] The display control unit 12 also has a function of displaying performance timing marks 15a, 15b, ... (hereinafter referred to as "timing marks") shown by "x" marks in Fig. 6 based on the data received from the receiving unit 11. The timing marks 15a, 15b, 15c indicate the performance timing (the timing to pluck the strings to produce sound) of the chord that is about to be performed.

[0038] 6 shows examples of displays that change on the fingerboard 5 in the order of (a) → (b) → (c) as the performance progresses from top to bottom of the figure. In the state of (a), the timing mark 15a displayed in the area between the frets closest to the first fret f1, which is the reference fret marked with a triangle, on the body 1 side corresponds to the chord to be played next, which is represented by the second fingering position mark 14.

[0039] The timing marks 15b, 15c correspond to the chords to be played in that order, one after the next, the next after that, and so on. However, it is sufficient to display at least the timing mark 15a corresponding to the chord to be played next, and it is not necessary to display the chords beyond the chord to be played next.

[0040] Here, the area between adjacent frets or between adjacent frets is taken as a unit, and this unit is taken as one beat. Based on this standard, the timing marks 15a, 15b, and 15c are displayed at positions that are moved from the first fret f1, which is the reference fret, toward the body 1 by the number of frets (the area) equivalent to the number of beats from that point to the timing to be played.

[0041] The timing marks 15a, 15b, and 15c move to the adjacent fret area one beat at a time in accordance with the tempo of the music piece, and move toward the reference fret. When the timing mark 15a passes the reference fret 1st fret f1 and reaches the fret area between the 0th fret f0, it is the performance timing of the chord corresponding to the timing mark 15a.

[0042] That is, in the state of (b), the chord corresponding to the timing mark 15a is being played, and at this point, the timing mark 15b becomes the timing mark corresponding to the next chord. From the timing mark 15b displayed in the area between the frets f2 and the third fret f3, it can be seen that the performance timing of the next chord corresponding to the timing mark 15b is two beats after the performance timing of the chord corresponding to the timing mark 15a, and from the timing mark 15c displayed in the adjacent area between the frets, it can be seen that the performance timing of the chord after the timing mark 15c corresponding to the timing mark 15 is three beats after the performance timing of the chord corresponding to the timing mark 15a.

[0043] If you advance one more beat, each of the timing marks 15b and 15c will move one fret space toward the 1st fret f1 side, resulting in the state of (c), and you will know that the timing to play the chord corresponding to the timing mark 15b is approaching. When the timing mark that has moved from the body 1 side passes the 1st fret f1, which is the reference fret, and is no longer displayed (when the performance of the chord corresponding to that timing mark is finished), a new timing mark is added to the end of the row of timing marks already displayed, in accordance with the performance timing of the chord corresponding to that timing mark (the number of beats until the performance starts) and is displayed.

[0044] 6, a second fingering position mark 14 corresponding to the next chord to be played is also displayed on the fingerboard 5. Therefore, it is preferable to determine the position of the reference fret so that these marks can be easily distinguished.

[0045] [Actions and Effects] In the first embodiment, the second fingering position mark 14 corresponding to the next chord to be played is displayed in the second area E2, which is a predetermined distance away from the first area E1, which is the position to actually press, toward the body 1. Therefore, the second fingering position mark 14 is not hidden by the player's fingers pressing the strings while playing, and the player can see the next chord to be played.

[0046] Also, although the second fingering position mark 14 is not the actual position of the string when the next chord is played, it shows the position of the fingers pressing the string, so that the second fingering position mark 14 makes it possible to know the shape of the fingers, unlike when it simply shows the chord name. This allows the player to imagine the next fingering shape before the second fingering position mark 14 moves to the first area E1 and is displayed as the first fingering position mark 13. Therefore, by simply shifting the shape of the second fingering position mark 14 and the imagined fingering shape a specified distance toward the head 3, the player can actually play with the correct fingering position, allowing for smoother performance.

[0047] Also, the timing marks 15a, 15b, and 15c let you know the timing of the chords to be played in the future. In particular, because the timing can be predicted as the timing marks move, you can calmly switch your fingering position to the fingering position of the chord to be played when the first and second fingering position marks 13 and 14 are switched. Furthermore, in the first embodiment, the first and second fingering position marks 13, 14 are made up of numbers indicating the strings, so when the player looks at the fingerboard 5 from diagonally above while playing, even if the fingering position marks are misaligned with the positions of the strings, the player can still accurately grasp the fingering positions. However, the marks are not limited to numbers.

[0048] In the above example, the reference fret is set to the 12th fret f12, and since the first area, E1, and the second area, E2, are separated by one octave, the second fingering position mark 14 is expected to help the player understand not only the hand shape but also the pitch. However, the reference fret does not have to be the 12th fret f12, as long as the marks are set in a position that is easy for the player to see. Also, the fret area between adjacent frets is used as a unit, and the area between adjacent frets is considered to be one beat, but other beats such as two beats or three beats may be used. Furthermore, the timing marks 15a, 15b, and 15c are not limited to cross marks.

[0049] [Second embodiment] Fig. 7 shows an example of the display of performance timing marks (hereinafter referred to as "timing marks") 16a, 16b and beat marks 17a, 17b in the second embodiment. In Fig. 7 as well, the display on the fingerboard 5 changes for each beat in the order (a) → (b) → (c) → (d). The first fret f1 marked with a triangle is used as the reference fret. The configuration other than the display of the timing marks 16a, 16b and beat marks 17a, 17b is the same as in the first embodiment. Therefore, the first and second fingering position marks 13 and 14 are displayed simultaneously with the timing marks 16a, 16b and the beat marks 17a, 17b.

[0050] The timing mark 16a displayed in the fret space adjacent to the first fret f1, which is the reference fret, is composed of an X mark and a number indicating the number of beats until the start of performance. Here, the number indicating the number of beats uses the number indicating the string. That is, the number indicating the number of beats is displayed along the string corresponding to the number. (a) indicates that the performance timing of the next chord is three beats later, and the number decreases by one beat each time from (b) to (c). Then, at (d), when the performance timing arrives, the timing mark 16a is replaced by a new timing mark 16b. In this way, the timing marks 16a and 16b are timing marks whose numbers indicating the number of beats until the start of performance change over time, and change according to the number of beats until the performance timing.

[0051] The beat marks 17a and 17b are each made up of a circle and a number indicating the number of beats of the chord to be played next. The numbers indicating the number of beats in the beat marks also use the numbers indicating the strings. In other words, the numbers indicating the number of beats are displayed along the strings that correspond to the numbers. In (a), the beat number mark 17a indicates that the next chord to be played will be two beats long, and that the performance timing will be three beats later. Since this number of beats does not change until the performance starts, the number on the beat number mark 17a remains "2." In (b) and (c), the number on the timing mark 16a changes, but the number on the beat number mark 17a remains "2." In (d), the timing for playing the chord corresponding to the timing mark 16a has come, so the number of beats of the chord being played, 2, is shown as the number of beats until the next playing timing, and the beat mark 17a is shown as the new timing mark 16b. Furthermore, the number of beats of the chord corresponding to this timing mark 16b, for example 4 beats, is shown as the new beat mark 17b.

[0052] [Actions and Effects] As described above, in the second embodiment, the timing marks indicate the performance timing of the next chord to be performed, and the beat marks indicate the number of beats of that chord. This allows the performer to grasp the performance timing in advance, enabling smooth performance.

[0053] Furthermore, since the number of beats of the next chord to be played is known in advance, the timing of the chord to be played after that is also known, allowing for smoother switching. In addition, the numbers indicating the beats in the timing marks and beat marks use the numbers indicating the strings, so it is possible to display them without requiring a new structure for indicating the beats.

[0054] The timing marks 16a, 16b and the beat marks 17a, 17b are not limited to the x marks and o marks, as long as it is possible to distinguish whether the displayed numbers indicate timing or beats. Also, beat marks indicating the number of beats of the corresponding chord may be added to the timing marks that indicate the timing by the moving position like the timing mark 15a in the first embodiment. For example, the number of beats can be displayed by numbers next to the cross mark. Furthermore, the display constituting the fingerboard 5 is not limited to an LCD, but may be an electroluminescence display or the like. [Industrial Applicability]
