- a keyboard instrument includes a keyboard section consisting of only a keyboard arranged in such a manner that a pitch is a whole tone, a whole tone, a half tone, a whole tone, a whole tone, a whole tone, and a half tone.
- a support portion for supporting the keyboard portion is a whole tone, a whole tone, a half tone, a whole tone, a whole tone, a whole tone, and a half tone.
- the keyboard portion is composed of only the keys arranged such that the pitch is a repetition of a whole tone, a whole tone, a half tone, a whole tone, a whole tone, a whole tone, and a half tone. That is, the keyboards are arranged without providing a keyboard (for example, a black key) that may cause a beginner or the like to retreat from a keyboard instrument. This makes it possible for a beginner to easily work on a keyboard instrument while securing the keyboard necessary for playing a song, and also to make it easier for a beginner to play. Since the number of keyboards and the like prepared for manufacturing a keyboard instrument can be reduced, the cost can be reduced.
- the keyboard portion is an aggregate of each of the above keys.
- the support portion has, for example, a support member that supports each keyboard from below, a casing that accommodates a part of each keyboard, and the like.
- the respective keys are all of the same color. According to such a configuration, all keys are made to have white keys, for example, so that a beginner can work on a keyboard instrument like a percussion instrument, and different colors and colors can be used for manufacturing a keyboard instrument. Since it is not necessary to prepare a shaped keyboard or the like, low cost dangling can be achieved.
- first storage means for storing information on a sound of a music piece, means for setting information on a key to which the music piece is transposed, and Second storage means for storing key information of the music, means for determining the key of the music based on the stored information of the sound of the music, and the storage means based on the key information of the determined music.
- the information on the sound of the song includes, for example, information on the sound used in the song, the number of times the sound has been used, and the like.
- the user of the keyboard instrument sets the key information of the transposition destination of the song, thereby adjusting the key of the song.
- the key can be automatically transposed to the set key. For this reason, the user does not need to set information such as the frequency for transposing the key of the music, so that it is easy to use especially for beginners.
- the first storage means for storing information on the sound of a song and information on the first key, which is information on the key of the song, and a key to which the song is transposed.
- Means for setting the key information of the first key the second storage means for storing the information of the second key that is the key information of the set key of the transposition destination, and the key information of the stored first music.
- the musical instrument further includes a performance support board slidably provided on each of the keyboards and in a plane where the respective keyboards are arranged.
- the musical instrument further includes a performance support board rotatably provided so as to be in contact with and separated from each of the keyboards.
- the performance support board can be slid or rotated so as to be superimposed on each of the keyboards at the time of performance or the like, and the performance can be performed using the performance support board. Therefore, it is possible to make the performance easier.
- the performance support board can be slid or rotated again and evacuated.
- the performance support board has a black keyboard, a color keyboard, a scale keyboard, or a numeric keyboard.
- the black keyboard, the scale keyboard, and the numeric keyboard are, for example, a transparent sheet that is slidably or rotatably provided with a black keyboard mark, a note name, and a number, respectively.
- the color keyboard is, for example, a translucent sheet that is slidable or rotatable. The translucent sheet is colored by sliding or rotating the translucent sheet so that the keys overlap with each other and look different colors. This allows the performance support panel to be used according to the user's preference. Can be made easier to play.
- a means for storing music information a plurality of key pressing units provided so that each of the keys can be pressed from above, and information on the music Means for controlling each of the key pressing sections based on the above, and further comprising an automatic performance section that can be placed on the support section.
- each key can be pressed from above by each key pressing portion. Therefore, it is possible to generate a delicate sound as if the player actually hit the keyboard.
- the automatic performance section can be mounted on or removed from the support section of a keyboard instrument, and is highly versatile. Since there is no need to provide an automatic performance section inside the keyboard instrument, low cost daggers can be achieved.
- a vibrating string provided for each of the keys, a hammer that strikes a string in conjunction with the pressed key, and And a pedal mechanism for moving the hammer by a semitone.
- the apparatus further comprises a damper pedal for continuing to vibrate the string vibrated by striking the string with the hammer, wherein the pedal mechanism is provided with the damper in an arrangement direction of the keyboard.
- a first pedal which is arranged on the lower note side of the pedal and is capable of lowering the sound of the depressed key by one semitone, and is arranged on the treble side of the damper pedal in the arrangement direction of the keys, and is depressed.
- a second pedal capable of raising the sound of the keyboard by a semitone.
- the right side of the keyboard is the treble side and the left side is the bass side as viewed from the performer
- this is used, for example, to lower the sound of the keyboard with the left foot pressed by the performer by one semitone, and This can be used to raise the sound of the keyboard when a foot is depressed by one semitone. Therefore, the player can operate the pedal intuitively, and the performance using the first pedal and the second pedal can be facilitated.
- the hammer can be moved to a low frequency side in the direction in which the strings are arranged by the first pedal, and the hammer can be moved by the second pedal. It can be moved to the treble side in the direction in which the strings are arranged. For this reason, for example, to reduce the sound Since a mechanism similar to the conventional shifting pedal for moving the hammer in the direction in which the strings are arranged can be used for the pedal mechanism for moving the hammer by a semitone, low cost can be achieved.
- the hammer is rotatable by the first pedal to a low frequency side around an axis substantially perpendicular to a direction in which the strings are arranged.
- the second pedal With the second pedal, it is rotatable around the axis toward the higher frequency side. Even in this way, the sound depressed using the left and right feet can be lowered or raised by a semitone.
- the keyboard portion is constituted by only the keyboards arranged such that the pitch is a repetition of a whole tone, a whole tone, a half tone, a whole tone, a whole tone, a whole tone, and a half tone. This makes it possible to provide a low-cost keyboard instrument which is easy to use for the user.
