Description

  When playing large stringed instruments such as cello and contrabass, this device is placed across the back plate of the resonance drum and attached to the stringed instrument, preventing the performer's body from directly hitting the back plate. It is related with the holding | maintenance tool which makes it possible to hold | maintain a stringed instrument, without impairing not only the vibration of this, but the resonance vibration of the whole resonance cylinder.

  Traditionally, when playing large stringed instruments, including cellos and contrabass, the instrument is stood by striking the floor with an end pin on the tail, and the performer sits on a chair in the case of a cello and places the resonance torso between his knees. Hold the instrument so that the upper part of the instrument is held by the left half of the instrument, and in the case of a contrabass, the performer also attaches the left half of the instrument to the instrument in a standing position and holds the upper part of the instrument with the right half of the instrument. Although the instrument is slightly laid down, the performer holds the instrument in a posture close to the standing position because a chair that is higher than usual is used. Depending on the performance posture, the performer's abdomen in the case of a cello, the left foot in the case of a contrabass, particularly the knee hits the back plate, and the vibration of the back plate is impaired.

  In either case, the performer does not press the back plate with high pressure at all times, but the abdomen or legs are placed against the back plate of the resonance cylinder to suppress the vibration of the back plate, and the front plate accompanying the vibration of the strings Is not smoothly transmitted to the back plate through the soul column, and the natural resonance vibration of the entire resonance cylinder is hindered. However, this problem has not been looked up to date, and it has been left to the improvement efforts by the performers themselves, and no active improvement measures have been proposed yet.

  The problem to be solved by the present invention is therefore to at least reduce, and preferably eliminate, the restraining action of instrument holding features by large stringed instrument players such as cellos and contrabass on the vibration characteristics of stringed instruments. .

  Therefore, the present invention attaches to a musical instrument when playing a large stringed instrument, prevents the performer's abdomen or leg from coming into direct contact with the back plate of the instrument, and exhibits the vibration characteristics inherent to the stringed instrument. An object of the present invention is to provide a holding aid for playing large stringed instruments that does not interfere.

  In order to achieve the above object, as a first problem solving means according to the present invention, a holding instrument for playing a large stringed instrument has at least a substrate having a length exceeding the back plate of the large stringed instrument, and both ends of the substrate. And a pair of back plate edge gripping tools attached to the substrate, the back plate edge gripping tools each along a base fixed on one surface of the substrate and an axis of the base perpendicular to the one surface of the substrate. It consists of a pair of substantially U-shaped holding legs that can be rotated about the rotation axis and parallel to each other, and the holding legs are sufficient to leave a gap between the back plate and the substrate when holding the back plate edge. It has a characteristic length.

  According to a second problem solving means of the present invention, in the holding aid for playing a large stringed instrument according to the first problem solving means, the position of the longitudinal direction of the base of at least one of the pair of back plate edge grippers can be adjusted. It is attached to a substrate.

  According to the present invention, the third problem solving means is a holding aid for playing a large stringed musical instrument according to the first or second problem solving means, wherein the holding leg of the back plate edge gripping tool is a round bar having an elastic cover on the surface. It is characterized by becoming.

  According to the present invention, a player of a large stringed instrument such as a cello or a contrabass attaches the holding aid of the present invention to the back of the instrument prior to performance, that is, preferably attaches the constricted portion of the resonance cylinder. Cross the board and pass it to the back of the musical instrument, make the pair of holding legs of the back board edge gripping tool at both ends of the board abut the edge of the back board, and leave a gap between the back board and the board. The back plate edge gripping tool is fastened and fixed to the substrate at a position where it is securely gripped from both sides. Thus, when the performer holds the instrument for performance, a part of the performer's body has been in direct contact with the instrument back plate in the past. It is reliably prevented that the resonance vibration of the is disturbed.

  An embodiment of a holding instrument for performance of a large stringed instrument according to the present invention will be described with reference to FIG. 1 in a state of being removed from the instrument, FIGS. 2 and 3 in a state of being attached to the instrument, and FIG.

  The holding auxiliary tool 10 according to the present invention includes an elongated plate-like substrate 11 and a pair of back plate edge grippers 12a and 12b attached upright near both ends of one surface of the substrate 11.

  In the figure, the substrate 11 has an outer shape with a saddle-shaped or cloud-shaped curve as an example, and one end side is wide and the other end side is narrow. In addition to facilitating the reduction of the overall weight of the narrow side, the substrate 11 of the present invention is not limited to the saddle shape, and may be a straight shape such as an elongated rectangle or a vertically long trapezoid. The substrate 11 is made of hard wood so that the natural frequency of the substrate is different from the resonance frequency of the stringed instrument so that the substrate does not resonate. Therefore, a light metal material or a synthetic resin material can be used as the substrate as long as such resonance vibration does not occur.

  A pair of back plate edge gripping tools 12a and 12b that stand upright at both ends of the substrate 11 are respectively a base 13 that is mounted on a surface of the substrate 11 by a known bolt and nut system with the rotating shaft 13a standing upright at the center. A substantially arcuate or rod-like turntable 14 rotatably coupled to the rotary shaft 13a at the center, and a pair of holding legs 15 which are preferably made of round bars and are held upright at both ends of the turntable 14 in parallel. An elastic cover 16 is provided on each leg 15 to absorb pressure and prevent slipping. At least one back plate edge gripping tool, 12b in FIG. 1, is a bolt (not shown) for tightening and fixing the base 13 to the substrate 11 so that the mounting position can be adjusted along the longitudinal direction of the substrate 11. It is attached to the substrate 11 through a pair of attachment long holes 17 that can slide through the through holes. Instead of the long holes, a plurality of holes arranged at equal intervals in the longitudinal direction of the substrate 11 may be used.

  Accordingly, the pair of holding legs 15 and the pair of parallel holding legs 15 of the back plate edge gripping tools 12a and 12b are substantially U-shaped, and the two holding legs 15 are formed on the rotating shaft 13a of the base 13 passing between them. It becomes rotatable about the axis. And the attachment of one back plate edge gripping tool 12b is loosened to maximize the distance between the gripping tools 12a and 12b, and as seen in FIG. 3, between the pair of back plate edge gripping tools 12a and 12b. Grasping both side edges of the back plate 22 at the constricted portion of the resonance cylinder of the contrabass 20, and fastening and fixing the back plate edge gripping tool 12b to the substrate 11 at a position leaving a gap between the back plate 22 and the substrate 11, The holding assisting tool 10 is attached to a stringed instrument, here a contrabass 20. Although not shown, the attachment to the cello is performed in the same manner.

  When attaching to a stringed instrument, it is more sure that the holding legs 15 are rotatable in each of the back plate edge gripping tools 12a and 12b. And attaching the elastic cover 16 to the holding leg 15 increases the frictional force of the holding leg 15 against the back plate edge simultaneously with the protection of the back plate edge, This is to prevent separation from the mounting position.

  FIG. 4 shows a performance state of the contrabass 20 equipped with the holding aid 10 of the present invention by the player P using the bus chair BC. The bass chair BC is taller than a normal chair, so even if you sit on the seat, the performer stands almost on the right foot, and the left foot and abdomen placed on the footrest of the bath chair BC stand the end pin 23 on the floor. Supports the right side of the bus 20. At this time, the player's left knee LK abuts against the substrate 11 of the holding assisting tool 10 attached to the back side of the contrabass 20 and is prevented from directly abutting against the back plate 22 of the contrabass 20. It is prevented that the original resonance vibrations are disturbed. When performing in a standing position without using the bath chair BC, the player's left waist comes into contact with the substrate 11 of the holding assisting tool 10, and the same effect can be achieved.
