Definitions

  • the present invention relates to a keyboard instrument having a keyboard.
  • a keyboard of a keyboard instrument is constituted by repeating an arrangement of white keys and black keys in order of white, black, white, black, white, black, white, black and white.
  • a tone interval of each of the arranged keyboard is set at a half step and the tone intervals of the respective white keys are set so as to repeat an arrangement of whole step, whole step, half step, whole step, whole step, whole step and half step.
  • a keyboard instrument such as an acoustic piano or the like that has strings is constituted so that, when a keyboard is touched a hammer strikes a string to generate a sound; and when a finger is detached from the keyboard a damper goes down to damp the string and thereby to stop vibrations.
  • An electronic keyboard instrument such as an electric piano is constituted so that, by making use of digital data of sounds, sounds are generated from a sound source.
  • an automatic transposing device for transposing a key of a piece of music.
  • an automatic transposition device having a transposition information setting unit for setting transposition information of a whole of a keyboard instrument and a transposition excluded part setting unit for setting a part that is not transposed is disclosed.
  • the electronic keyboard instrument has an automatic player capable of, for instance, memorizing and reproducing data played by a player.
  • Patent literature 1 JP-A No. 09-319368 (paragraph [0012] and Fig. 1 )
  • the present invention intends to provide a keyboard instrument that can be readily used by a beginner and is less expensive.
  • a keyboard instrument as the one shown in document FR 2559604 , comprising: a keyboard portion made only of keyboards in which tone intervals are arranged so as to repeat an arrangement of whole step, whole step, half step, whole step, whole step, whole step and half step; and a support portion that supports the keyboard portion.
  • a keyboard portion is constituted only of keyboards in which tone intervals are arranged so as to repeat an arrangement of whole step, whole step, half step, whole step, whole step, whole step and half step. That is, without disposing keyboards (for instance, black keyboards) that can alienate a beginner from a keyboard instrument, keyboards are arranged. Thereby, while securing keyboards necessary for performing a piece of music, a beginner is allowed lightheartedly addressing a keyboard instrument and can readily play. Since the number of keyboards preparing for manufacturing a keyboard instrument can be reduced, the lower cost can be achieved.
  • the keyboard portion is an assembly of individual keyboards.
  • the support portion has, for instance, a support member that supports the individual keyboards from below or a casing partially accommodating the individual keyboards.
  • the keyboards are all in the same color. According to such a configuration, when all the keyboards are made white keyboards, a beginner can cope with a keyboard instrument same as coping with a percussion instrument, and since there is no need of preparing keyboards of different colors and shapes when manufacturing a keyboard instrument lower cost can be realized.
  • the present invention provides a keyboard instrument, comprising:
  • the keyboard may comprise: a first storing means for storing an information of sounds of a piece of music and a first key information that is a key of the piece of music, a setting means for setting a second key information that is an information on a destination of transposition of the piece of music, a second storing means for storing the second key information set by the setting means, a transposing means for transposing sounds of the piece of the music stored by the first storing means to sounds corresponding to the second key information based on the second key information stored by the second storing means.
  • a feature of the keyboard as now claimed is a performance support plate disposed turnable so as to be attachable to or detachable from the keyboards.
  • the performance support plate can be slid or turned during the performance to superpose on the respective keyboards and thereby utilized to perform. Accordingly, the performance can be more readily carried out. Furthermore, at the end of the performance, the performance support plate is once more turned to arrange only for instance white keyboards, and thereby a space formed on the keyboards can be effectively used.
  • the performance support plate may have a black keyboard, a color keyboard, a scale keyboard or a numerical keyboard.
  • the black keyboard, scale keyboard and numerical keyboard, respectively, are ones obtained by marking black keyboard marks, sound names and numerals on a transparent sheet disposed for instance slidable or turnable.
  • the color keyboard is for instance a slidable and turnable translucent sheet and is colored so that when the translucent sheet is slid or turned to superpose on the respective keyboards, the respective keyboards may appear in different colors.
  • the keyboard instrument may comprise an automatic performance unit capable of being placed on the support portion: wherein the automatic performance unit has a storing means for an information of a piece of music, a plurality of key touch devices disposed so as to be touchable with each of the keyboards from thereabove and a controller that control each of the key touch devices based on the information of the piece of music.
  • the respective keyboards can be pressed from the above by use of the respective key touch portions. Accordingly, subtle sounds like ones when a player actually strikes a keyboard can be generated. At this time, by controlling amounts of movement and speeds of the respective key touch portions, more delicate dynamics of sounds can be generated.
  • the automatic performance portion being able to attach by placing on the support portion of the keyboard instrument or detach therefrom, is excellent in the versatility. There is no need of disposing the automatic performance portion inside of the keyboard instrument; accordingly, the lower cost can be achieved.
  • the keyboard instrument may also comprise a vibratable string disposed corresponding to each of the keyboards, a hammer that strikes a string in conjunction with a touched one of the keyboards, a pedal mechanism for shifting the hammer by a half step to each of the strings.
  • a vibratable string disposed corresponding to each of the keyboards
  • a hammer that strikes a string in conjunction with a touched one of the keyboards
  • a pedal mechanism for shifting the hammer by a half step to each of the strings.
  • the keyboard instrument may also comprise a damper pedal for keeping the string vibrated once being struck with the hammer, wherein the pedal mechanism includes, a first pedal that is disposed on a lower pitch sound side than the damper pedal in a direction of an arrangement of the keyboards and can make sounds of the keyboard lower a half step, and a second pedal that is disposed on a higher pitch sound side than the damper pedal in a direction of an arrangement of the keyboards and can make sounds of the keyboard higher a half step.
  • a right side of the keyboards seen from a player is a higher pitch sound side and a left side of the keyboards seen from a player is a lower pitch sound side
  • a left leg of the player can be used to make a sound of a touched keyboard a half step lower
  • right leg can be used to make a sound of a touched keyboard a half step higher.
  • the hammer may be capable of shifting by use of the first pedal toward a lower pitch sound side in a direction where the respective strings are arranged and by use of the second pedal toward a higher pitch sound side in a direction where the respective strings are arranged. Accordingly, a mechanism similar to an existing shifting pedal where a hammer is shifted in a direction of arrangement of the respective strings, for instance, to make the sound lower, can be used in a pedal mechanism for shifting a hammer by a half step, resulting in achieving the lower cost.
  • the hammer may be capable of turning by use of the first pedal toward a lower pitch sound side around an axis substantially perpendicular to a direction where the respective strings are arranged and by use of the second pedal toward a higher pitch sound side around the axis.
  • touched sounds can be made a half step higher or lower.
  • a keyboard instrument that can be readily used by a beginner and is low in the cost can be provided.

  • the keyboard instrument 10 includes a keyboard portion 4 for inputting sounds.
  • the keyboard portion 4 has a plurality of keyboards 21 for indicating timings or the like of sounds that are produced or silenced ( Fig. 2 ).
  • the keyboard portion 4 is connected through a keyboard portion interface circuit 5 that scans the on/off of the respective keyboards 21 to detect operated keyboards 21 to the CPU 1 or the like.
  • the CPU 1 or the like is connected through an internal interface to a setting panel 11 capable of setting a key that is a destination of transposition. For instance, when a user operates a keyboard instrument 10 to input to set a key of a piece of music that the keyboard instrument 10 reproduces, the setting panel 11 is used.
  • the setting panel 11 is provided with, for instance, operation buttons not shown in the drawing, and when a user operates the operation buttons the CPU1 sets a destination of the transposition.
  • the CPU 1 or the like is connected through the internal interface to an automatic transposition program memory 6 where an automatic transposition program is memorized.
  • the automatic transposition program by discriminating a key of a piece of music inputted outside of the keyboard instrument 10 and, based on information of sounds stored in the RAM 3, transposing the sounds of the discriminated key to sounds of a key set by the setting panel 11, is used to transpose a key.
  • a piece of music inputted when for instance a user strikes a keyboard 21 can be considered. In what follows, this is called an initial setting.
  • the user when the user is a beginner, it is difficult for the beginner to input a certain piece of music. Accordingly, in this case, the user, irrespective of a tempo or the like of the piece of music, has only to strike a keyboard and input one sound at a time. In this case, the user may input while seeing a musical score. As the musical score at this time, musical scores that can be used in the keyboard instrument 10 according to the embodiment have only to be prepared in advance.
  • the keyboard instrument 10 includes a keyboard portion 4 and a support portion 17 capable of supporting the keyboard portion 4.
  • the keyboard portion 4 is constituted only of keyboards 21 arranged in an X-direction so that musical intervals may repeat an arrangement of whole step, whole step, half step, whole step, whole step, whole step and half step.
  • the individual keyboards 21 are all set in the same color, for instance, in white, and there is no black keyboard. Although an example where all the keyboards are in the same color is shown, keyboards 21 corresponding to, for instance, [do] may be colored differently from other keyboards, or colors of keyboards of individual octaves may be differentiated from each other.
  • a position of a keyboard 21 for generating a keynote of a key that is a destination of the transposition set by the setting panel 11 is preferably set at a position of a central do of the keyboard portion 4.
  • the position may be marked with a mark or made luminescent so as to be apparently obvious.
  • a housing portion 18 where a performance support plate 15 for supporting performances is housed is disposed on a top surface of the support portion 17, on a remote side in a Y-direction seen from the respective keyboards 21 side.
  • the performance support plate 15 is disposed on the respective keyboards 21 slidably in a Y-direction from an initial setting position S in a plane where the respective keyboards 21 are arranged.
  • the performance support plate 15, when slid in a Y-direction, can be moved to a space on the respective keyboards 21 to superpose on the keyboards 21.
  • the performance support plate 15 is one in which on a transparent sheet for instance, sound names such as [do, re, mi, fa, sol, la, si, do] are marked.
  • the CPU 1 by use of information of sounds of a piece of music and the frequencies of use of sounds stored in the RAM 3 according to an automatic transposition program, discriminates a key of an inputted piece of music. For instance, when information of inputted sounds is selected in a decreasing order of the frequencies by 8, musical intervals of the selected respective sounds are calculated, and the musical intervals are whole step, whole step, half step, whole step, whole step, whole step and half step, it is judged as a major key. On the other hand, when musical intervals between the similarly selected respective sounds are whole step, half step, whole step, whole step, half step, whole step and whole step, it is judged as a minor key.
  • a sound lowest in the pitch of the information of 8 sounds is judged as a keynote.
  • a key of the piece of music is judged as, for instance, [E major].
  • sounds of a key of the piece of music judged in the steps 10 and 11 are shifted to sounds of a key set at the setting panel 11 to transpose. For instance, when a key of a destination of transposition set by the setting panel 11 is [C major] and a key of the piece of music judged in the steps 10 and 11 is [E major], an amount corresponding to four half steps is set to shift.
  • the keyboard instrument 10 includes the keyboard portion 4 made only of the keyboards 21 arranged so that the musical intervals may repeat an arrangement of whole step, whole step, half step, whole step, whole step, whole step and half step. That is, without disposing the black keyboards that may hold beginners off the keyboard instrument 10, the respective keyboards 21 are arranged. Thereby, while securing the respective keyboards 21 necessary for performing a piece of music, the beginners can be made so as to lightheartedly address the keyboard instrument 10 and to be able to readily play. Since the number of the keyboards 21 prepared to manufacture the keyboard instrument 10 can be reduced, the lower cost can be realized.
  • colors of the respective keyboards 21 are all the same.
  • the beginner can address the keyboard instrument 10 same as addresses a percussion, and since there is no need of preparing the keyboards 21 of different colors and shapes for manufacturing the keyboard instrument 10, the lower cost can be realized.
  • an electronic keyboard instrument 10 is exemplified.
  • the number of the keyboards, the hammers that strike the strings when the keyboards are touched and strings can be reduced, the lower cost can be achieved.
  • information or the like of a key set by the setting panel 11 is stored and the automatic transposition program performs the automatic transposition.
  • the user without setting information of the number of degrees for transposition, can easily transpose.
  • the player while hearing the performance of the transposed piece of music, can play at the same key.
  • a transposed musical score is preferably prepared in advance. Thereby, since the player can play while seeing the musical score prepared in advance, the performance can be more easily carried out.
  • the performance support plate 15 is disposed on the respective keyboards 21 slidably in a Y-direction in a plane where the respective keyboards 21 are arranged. Accordingly, during the performance, the performance support plate 15 can be slid and superposed on the respective keyboards 21, and thereby the performance support plate 15 can be used to perform. Accordingly, the performance can be more easily carried out. Furthermore, when the performance is over, by effectively making use of a space on the respective keyboards 21, the performance support plate 15 can be slid again to take shelter. That is, since there is no black keyboard, the performance support plate 15 can be readily slid.
