Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement of a button type (typewriter type) musical instrument keyboard in which one kind of keys are arranged on a table in a vertical and horizontal order and mutual pitch relations.

[0002]

2. Description of the Related Art In the keyboards of piano organs that are now popular, the seven tones included in the C major scale and the remaining five tones are differentiated from each other, so that the fingering is different for each of the twelve tones. As the number of tone symbols increases, finger transposition becomes more difficult, which is a hassle for transposing. Also, in order to play a wide range smoothly, there is a unique limitation of fingering, and advanced technology is required for fast and accurate performance by moving or jumping a range of several octaves. Button-type accordion keyboards and Yanko-type keyboards have been used as a method of releasing conventional keyboard instruments from the trouble of transposing, but since the pitch arrangement is unique, it is difficult to learn, and it can not be applied elsewhere. It hasn't. In recent years, electronic sound sources have become more sophisticated and multifunctional due to the development of computer technology, but the keyboard mechanism is the most convenient and reliable operation device for them, but the conventional musical instrument keyboard as a means of playing has There are many shortages. Further, as a performance device that has been commercialized to date, there is a form in which the function of a guitar is electronic. Since this type of product is premised on that the guitar player operates it, it is necessary to learn the characteristics of each product and the tips on playing after gaining a good understanding of how to play the guitar. The method is not established.

[0003]

DISCLOSURE OF THE INVENTION The present invention has renewed the form, shape and arrangement of the keyboard customarily used before the establishment of the average rate in Western music, which is impossible or expensive in the past. It was devised to overcome the performance restrictions that required skill.

[0004]

The features of the present invention will be described below with reference to concrete examples. FIG. 1 shows the present invention in which (a) the keyboard rows are set in the horizontal direction, and (b) the pitch difference between adjacent keys in adjacent rows is (B) 6
As a semitone, (c) is a part of a sample of a keyboard row for 5 octaves from C2 to B6 of the embodiment arranged such that the pitch increases from left to right and from front to back. Now, let us say that the horizontal arrangement of keys in FIG. 1 is a column, and the location of the key in the column is a digit. The vertical arrangement of the keys in the figure is expressed as having the same number of digits. In the present invention, if the pitch difference from the nearest key in the next row is X semitone,
When one row of X-digit keyboard rows is piled up, all twelve tones are included in it. In Drawing 1, it is C in the range of 6 digits and 10 columns.
5 octave semitone strings from 2 to B6. In this way, if all the necessary tone ranges are stored in the X-digit keyboard row, the tone range shift that was conventionally only in the lateral direction can be efficiently replaced in the depth direction. The pitch arrangement of the present invention is easy to understand when the strings are regarded as strings of a stringed instrument and the digits are considered as frets. In the embodiment, when the pitch difference between the adjacent keys of the adjacent strings is (A) 7 semitones, it is of the violin mandolin type. , (C) Five semitones can be considered in accordance with standard string tuning for a contrabass, bass guitar, etc., and therefore has the advantage that those experienced can easily understand. In addition, the standard tuning of a guitar has a part where the pitch difference is not constant, but it is considered that it is basically 5 semitones. However, in the case of a wide stringed instrument, it is basically unnecessary in the present invention, although it is necessary to move the position many times in the case of wide range movement. Also, if there is a part where the pitch difference between the keyboard rows is not constant, the position shifts at that part, so you have to be proficient in special fingering and chord deformation only in that part, which hinders the transposition and improvisation of the poetry. Becomes If the pitch differences are all constant, the pitch can be grasped by the law that unifies the entire keyboard. In addition, since 7 semitones correspond to the perfect 5th and 5th semitones, there is an advantage that you can use the technique of playing two keys simultaneously with one finger to make the sound thicker. However, the feature of the present invention is that the range shift, which used to be only horizontal movement in the past, is replaced with the depth direction. Therefore, in the case of 6 semitones as shown in FIG. The keys are related to octaves and are in the same digit, but in the seventh semitone they are major 9th and in the fifth semitone they are minor 7th, and the octave shifts by two digits. Therefore, in the case of playing up and down with the same tone pattern over many octaves, 6 semitones can be played with the same fingering without vertically changing the position, but with 7 semitones and 5 semitones, the fingering can be changed without changing the position. It is necessary to select whether to change the position without changing the fingering. Therefore, it can be said that 6 semitones is convenient when dealing with a wide range. Now, considering the fingering for one hand, when practicing a tone pattern with a vertical movement within the X digit for one tone, if there is no lack of range, if there is a 2X-1 digit keyboard row, the other tone will be positioned. You can play with the same fingering by changing. And considering the fingering for both hands, when practicing the sound pattern by vertical movement within 2X digits with X digits for right hand + X digits for left hand, 12 tones are obtained with a keyboard row of at least 3X-1 digits. You can play with the same fingering. According to the present invention, if one kind of fingering is memorized, 12 tones of melody and chords can be played as they are by changing positions, and since there are several kinds of fingering for one melody and chord, there are several kinds of fingering before and after the performance. You can select an efficient fingering by connecting. In the conventional keyboard, the pitches are aligned in a straight line, and the keys are arranged in a zigzag manner, which causes a problem of finger clogging when moving the range. However, in the present invention, since the number of digits is increased and the key with a high pitch can always be placed in the left back and the key with a low pitch in front of the right at a position near the center, finger clogging can be avoided. In the present invention, it is possible to hold a very distant pitch at the same time with one hand, and assuming that the size of each key in FIG. 1 is a square having the same length and width as the white key width of the conventional keyboard, 4 octaves Even small women can easily reach. Therefore, it is possible to take open harmonies that were not possible with one hand in the past. Even when moving to a distant range, the sound is not interrupted. Stride playing is also facilitated by taking the base with your thumb and playing the chord with your other fingers. The lower the pitch of the bass, the deeper it is and the more effective it is. However, in terms of music, chords have a limitation in the bass, which has been a difficulty in playing. According to the present invention, the pitch difference can be widened and a clear effect can be achieved with a complicated rhythm such as 16 beats. Further, in that case, it is easy to reverse the roles of both hands and play the melody with the left hand and the accompaniment with the right hand, and there are many restrictions in the conventional keyboard because both hands are crossed. In the present invention, since the musical range is moved vertically, if the number of digits is sufficient, even a sound pattern in which the musical ranges of both hands collide will not cross hands or overlap. In FIG. 1, three sets of 6-digit and 10-row keyboard rows are connected in a staircase pattern so that the scales are connected to each other.
Therefore, there are three keys for all the pitches from C2 to B6. Of course, this keyboard row can be added in any number of sets with the same pattern if necessary. In the organ, the keyboards are arranged like two steps, three steps and stairs, but in the present invention, they can be arranged side by side without a gap and treated as one keyboard, or can be divided by the number of digits to distribute the timbre. In the present invention, since there are a plurality of keys having the same pitch, two keys among them can be played alternately to easily play a tremolo such as a stringed instrument or a percussion instrument with one hand. In FIG. 1, there is a range of 5 octaves even with only eight columns and eighteen digits from the third column to the tenth column. In the present invention, if the keyboard row is lengthened by X digits, the pitch range will not change even if it is reduced by one row, but there will be performance restrictions in the high and low pitch ranges, such as tremolo not being possible at the X digits of the highest and lowest pitch ranges. . As shown in FIG. 1, high playability can be maintained in the entire range by setting a column starting from the middle digit and a column ending at the middle digit. The present invention facilitates chromatic glissandos, which is not possible with conventional keyboards. And if there are X + 12 digits, one octave of chromatic glissando is possible from any pitch. In that case, if a chord is taken within X digits, a chromatic glissando of 1 octave can be made with the chord. The more digits in the keyboard row, the wider the glissando. Although it is not general, if the pitch difference between the adjacent keys in the adjacent rows is (E) 3,5 semitones in the present invention, it is possible to incorporate into the performance a quarter note required in contemporary music and folk music. it can. In this arrangement, the pitch difference between keys of the same digit every other row becomes 7 semitones, and if you select an odd row and play
If you add an even number of rows, you will hear a quarter note. Even in this case, many characteristics of the present invention are maintained such that 24 tones obtained by dividing one octave can be played with the same fingering. FIG. 2 shows the present invention in which (a) the keyboard rows are set in the vertical direction, and (b) the pitch difference between adjacent keys in adjacent rows is (D) 4
As a semitone (c) A part of a sample of a three-octave keyboard row from C1 to B3 of the embodiment arranged so that the pitch increases from the front to the back and from left to right, which is used as a foot keyboard Is. This arrangement also has octave-related keys in the same digit. The pitch difference between adjacent keys in adjacent rows is 6 semitones or 4
If you make a semitone, the 12 tones will be arranged in 2 rows and 6 digits or 3 rows and 4 digits, and you can treat them as one unit. The foot keyboard of a conventional organ is much larger than the hand keyboard, and two octaves of the foot keyboard are wider than five octaves of the hand keyboard, but two octaves make the Bach organ tune play like a musical score. Is not enough. Since the toes and heels of both feet are used, the length is required, and it is heavy and takes up space.
Since the width of the keyboard is wide and it can be operated with both feet, there are many restrictions on the possible sound types, such as low mobility especially near the edges. It is unsuitable for popular music after rock and funk, where the bass line is inseparable from the width and range and the bass line is inseparable from the establishment of the music. The short keyboard that is popular in electronic organs
There are more restrictions as the heels cannot be used and the number of keys is small. In Drawing 2, the key length should be about one-third of the player's foot length, and the four digits should be covered by sliding the back two keys with the toes and the front two keys with the heel to cover. You can play a wide range by moving your foot. The three chords are arranged in two digits, so only the tip of the toe can be used, and the whole scale can be played quickly and smoothly with one foot by using the toe and heel alternately for the whole note and sliding a semitone. Then, by connecting two sets of four-digit columns, the troublesome transposition is eliminated.
With this arrangement, the width of the entire keyboard can be made extremely compact. Assuming that the width between two rows is the same as the width of the white key of the conventional keyboard, 3 octaves in the figure for 10 keys, C for the conventional keyboard.
It is one octave from 1 to E2 and one third of the width. Therefore, two keyboards of the same arrangement for both left and right feet can be placed side by side at the foot. Therefore, in the present invention, by alternately playing different keys with both feet, it is possible to perform tremolo, continuous movement to a distant range that is not influenced by the preceding and following musical patterns, and a quick riff pattern and fill-in of complicated musical patterns. . In addition, the range of movement of the foot is small, and the posture is stable because it is not biased.

[0005]

The present invention has a high degree of suitability for playing an electronic sound source, which the conventional keyboard does not have. In the conventional keyboard, when the keyboard is divided in order to distribute a plurality of tones, the range is naturally reduced in proportion. However, in the present invention, since the number of keys is originally large with respect to the range, the number of divisions and the range are not proportional. Even if the drawing 1 is divided vertically by 6 digits, the playing range is limited, but the range is not reduced. It is also possible to set a large number of digits on the premise of division. In addition, although the range is reduced by horizontal division, one finger can reach many keys with one hand, so you can play an organic performance by taking a bass or counter melody with your thumb and playing a chord or main melody with another tone with another finger. Further, it is possible to assign different tones to each row, for example, to assemble a harmony of a chord from the top with Tp / As / Ts / Tb brass or Fl / Ob / Cl / Fg. Since wind instruments have different overtones depending on the range, even if they belong to the same genre, the timbre of the same pitch has different characteristics depending on the size of the instrument. However, in the conventional single-row keyboard, there was no choice but to cut a part of the keyboard and assign it to a wider range. In the present invention, the whole range or most of the same range of musical instruments can be assigned to a large number of keyboard rows, and can be effectively combined and incorporated into the performance. In the conventional keyboard, all positions of the stringed instrument cannot be assigned at one time, but in the present invention, one string is assigned to one row and a special effect is set for each row, so that a performance that cannot be performed with the conventional keyboard can be performed. Each row has a single trigger that gives you the nuances of hammering on, pulling off and glissando. Effective when incorporated into an arpeggio. You can reproduce the effect of setting an independent pitch bender for each row and playing two strings at the same time to bend only one. You can set an independent portamento for each row, press one key for each row, take a chord, and move horizontally to create an effect similar to pedal steel. The present invention not only excels in the imitation of the playing method of a stringed instrument, but also provides a tone pattern and an emphasized effect which are not possible with the original instrument. You can also use the foot keyboard as a single trigger and divide the tone color into thumb pick and pull in the range to produce the effect of slap playing style,
It is not impossible to change the timbre on the left and right and play the melody and bass at the same time with both feet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2, the keys are lined up without any gaps, but there may be gaps in the upper, lower, left, and right. If there are gaps, the keys can be made smaller to make the whole more compact. The top surface of the key may be vertically or horizontally long, and may be round or another shape. A thin touch switch may be used if initial touch detection is not required, and a lever may be keyed like a typewriter when mechanically connecting to a tracker or action. In the present invention, since the conventional technique can be applied to the mechanism and function of one key, it can be replaced and connected to the sound source section if it has compatibility with the conventional keyboard. There are technical problems in mechanically connecting to a piano or pipe organ, but it is not difficult to operate multiple pianos at the same time with one keyboard if they are electrically connected.

[0007]

Unlike the conventional keyboard, the present invention is fast for learning because it does not require learning new fingering each time the tone changes, and is suitable for instrumental players who are not good at keyboard musical instruments. It is also convenient for learning and research. Since it is not affected by tonality in principle, it is suitable for modern music with many transpositions and atonal music, and it is also suitable for polyphonic performance because of its high degree of freedom in the range and tone pattern. In the conventional keyboard, it is usually necessary to manufacture six types of white keys and seven types of black keys with different shapes in a required ratio and arrange them in a regular manner, and the white keys are thin and the long ends are suspended in the air. Because of this, there were cases where it could break in an accident. In the present invention, since only one type of key that is smaller than the conventional one is required, the production efficiency is high and the risk of breakage is low. Even if only the size of the keyboard is compared, the present invention can reduce the volume even in the same range as the conventional keyboard, and in particular, can narrow the width. Since it does not take up space, the costs of production, storage and transportation can be reduced. It is easy and flexible for users to carry and install. Conventional musical instruments, including keyboards, are unable to fully utilize the capabilities of electronic tone generators, which are becoming increasingly sophisticated, and the weight of sequencers in musical performance is increasing. INDUSTRIAL APPLICABILITY The present invention has the effect of bringing back the enjoyment of drawing out the versatile ability of an electronic sound source in real time as much as possible from the machine to the human hand.
