Description

  The present invention relates to a percussion instrument that is easy to carry, can be played while standing, and can be changed in pitch.

  Traditionally, there is an instrument called Udu. Udu is a pot made of earthenware, and is a percussion instrument having one or more openings on the side. The performer sits on a chair or crosses the floor, puts a donut-shaped cushion on the front, and puts udu on it. A sound is produced by hitting one of the openings provided in the Udu with a palm or by hitting the body of the Udu. Since it is possible to perform with such a simple operation, it can be performed without musical knowledge such as chords and tones. Udo has various shapes and sizes, each with a different pitch and tone.

  However, because udu is made of earthenware, it may be broken or damaged by impacts during transportation. In addition, since it is used while sitting on a cross or a chair during performance, it cannot be performed in a standing state and is not suitable for outdoor performance.

  In addition, when trying to perform an ensemble or ensemble with Udo, it is not possible to change the pitch with one Udu, so it is necessary to prepare multiple Udus with different shapes and sizes.

  Accordingly, an object of the present invention is to provide a percussion instrument that is easy to carry, can be played while standing, and can be changed in pitch.

  In order to achieve the above object, the percussion instrument of the present invention has a hollow body part, an opening formed in the body part to resonate the sound, and a pitch by being attached to and detached from the body part. It is characterized by having a pitch changing means for changing, and an opening / closing portion for opening and closing the trunk portion in order to attach and detach the pitch changing means to and from the inside of the trunk portion.

  Also, a plurality of the openings are perforated, and at least one of them is a striking surface, the pitch changing means is an attachment that can be attached to and detached from the openings, or the pitch changing means Is configured to be detachable from the back surface of the opening / closing part, or the pitch changing means is a hollow container provided on the back surface of the opening / closing part, the container has a lid, and the lid is attached / detached Thus, the pitch can be changed, or the body portion can have a stopper for passing the strap.

  According to the present invention, it is possible to change the pitch of a sound in a wide range by opening an opening / closing part provided in a body part formed of a hollow resin and attaching a pitch changing means inside the body part. . Moreover, since the trunk | drum is resin, it is easy to carry.

  By providing a stop for passing the strap through the body part, it is possible to perform while standing with the strap.

  Next, the percussion instrument of the present invention will be described with reference to the drawings. FIG. 1 is a view showing a percussion instrument of the present invention, in which (a) is a top view and (b) is a front view. The percussion instrument 1 is formed by forming a resin such as vinyl chloride into a cylindrical shape, and includes an upper portion 2 and a bottom portion 3 having the same outer diameter, and a central portion 4 having a smaller outer diameter. The upper part 2, the bottom part 3, and the central part 4 are combined to form a body part 5. In the present embodiment, the body portion 5 has the outer diameter of the central portion 4 smaller than that of the upper portion 2 and the bottom portion 3, but the present invention is not limited to such a form. For example, the upper part 2, the bottom part 3, and the central part 4 may have the same outer diameter. Further, the present invention does not limit the body portion 5 to a cylindrical shape.

  The upper portion 2 is closed at the upper end, and a first opening 6 is formed in the upper surface portion. Further, a second opening 7 is formed in a side surface portion of the upper portion 2. The opening 6 and the opening 7 are circular holes connected to the inside of the hollow body 5, and circular rubber sheets 6 a and 7 a formed of an elastic body such as rubber are attached to the periphery thereof. ing. At the time of performance, a sound is produced from the other opening by hitting one of the openings with a palm so as to close the opening. Since the circular rubber sheets 6a and 7a are attached, air does not leak from between the palm and the openings 6 and 7, so that a clean sound can be heard. Further, since the rubber sheets 6a and 7a also function as cushions, it is possible to prevent the palm from becoming painful during performance. As a performance method, in addition to hitting the openings 6 and 7, the body 5 and the upper surface of the upper part 2 may be hit. In this case, sound is emitted from the openings 6 and 7.

  A stopper 11 is attached to the upper part 2 and the bottom part 3. By attaching a strap or the like to the stopper 11 and putting it on the shoulder, the performer can perform with the percussion instrument 1 standing. At this time, if the surface of the body portion 5 is processed into a satin finish, it becomes slippery and the percussion instrument 1 is stable and easy to play.

  An opening / closing part 8 is provided on the bottom surface of the bottom part 3. The opening / closing part 8 is screwed into the bottom part 3 and can be removed by turning the handle 9. When the opening / closing part 8 is removed, the inside of the body part 5 can be accessed.

  Further, four legs 10 are provided on the bottom surface portion of the opening / closing part 8. As a result, it is possible to perform with the percussion instrument 1 placed on the floor or the like.

  The performer performs with the percussion instrument 1 placed on the floor or the like as described above, or performs while standing on the shoulder, and holds the percussion instrument 1 on the thigh while sitting on a chair. You can also play in such a posture. Since the percussion instrument 1 is made of resin, even if it is placed on an unstable place such as a thigh, there is little possibility of damage when dropped.

  2A and 2B are views showing the opening / closing part, where FIG. 2A is a top view, FIG. 2B is a cross-sectional view with a lid provided on the opening / closing part removed, and FIG. 2C is a bottom view. A cylindrical container 12 which is a pitch change means is integrally provided on the back surface of the opening / closing part 8. A screw thread 13 is formed in the lower part of the container 12, and the opening / closing part 8 is fixed to the body part 5 by screwing with the bottom part 3.

  The container 12 has a lid 14 at the top. The lid 14 is screwed into the container 12 and can be removed from the container 12 by grasping and turning the handle 15 provided on the upper surface.

  When the opening / closing part 8 is attached to the bottom part 3 with the lid 14 attached, and when the opening / closing part 8 is attached to the bottom part with the lid 14 removed, the inside of the body part 5 corresponds to the hollow volume of the container 12. The volume changes and the pitch changes. That is, in the state where the lid 14 is attached, the volume inside the body portion 5 becomes small, so that a high sound can be produced. On the other hand, when the lid 14 is removed, the volume of the body portion 5 is increased by the volume of the container 12 and the sound is lower than when the lid 14 is attached. As described above, the container 12 can change the pitch of the percussion instrument 1 by attaching and detaching the lid 14.

  On the upper surface of the lid 14, there is a cross 16, and on the inside of the container 12 is a circle 17. These marks are attached by sticking a seal of each shape or by a method such as printing. The mark 17 may be attached to the outside of the container 12.

  FIG. 3 is a sectional view of the percussion instrument of the present invention. The outer diameter of the central part 4 is substantially equal to the inner diameters of the upper part 2 and the bottom part 3, and the end part of the central part 4 is fitted in the upper part 2 and the bottom part 3. In addition to this, an embodiment in which the upper portion 2, the bottom portion 3 and the central portion 4 are integrally formed may be used. An acoustic tube 18 in which resin or the like is formed in a cylindrical shape is attached to the second opening 7. The acoustic tube 18 is bent at a substantially right angle at the end attached to the second opening 7, and the other end faces the container 12 side. The acoustic tube 18 is provided to adjust the basic pitch and lengthen the lingering sound. The acoustic tube 18 allows the percussion instrument 1 to be adjusted to an optimal pitch with an optimal performance size.

  The first opening 6 has an attachment member 19 that protrudes into the body 5, and an attachment 20 that is a pitch change means is attached to the first opening 6. The attachment 20 is a cylinder formed of resin or the like, and is attached by screwing a thread groove provided on the inside with a thread of the mounting member 19. The attachment member 19 is provided with a V mark 21 on the inside of the cylinder by sealing or printing.

  FIG. 4 is a front view of the attachment. Several types of attachments 20 are prepared depending on the length. FIG. 4A shows an example of a long attachment 20, which is a combination of two cylinders having different diameters. This may be integrally formed. FIG. 4B is an example of a short attachment 20. The longer the attachment 20 is, the lower the pitch produced by the percussion instrument 1, and the shorter the attachment 20 is. Therefore, the highest sound is produced when the attachment 20 is not attached.

  The surface of the attachment 20 in FIG. 4A has a □ mark 22, and the short attachment 20 has a Δ mark 23. These are also attached by sealing or printing, like the marks provided on the container 12 and the lid 14. By providing such a mark, the state in which the lid 14 is removed and the attachment 20 is not attached is represented as “◯ -V”, and the state in which the lid 14 is attached and the long attachment 20 is attached is represented as “×-□”. Since the pitch can be expressed by symbols, communication between performers is facilitated when performing a ensemble using a plurality of percussion instruments 1.

  Here, the x mark 16 provided on the lid 14 indicates that the lid 14 is screwed to the container 12, that is, the container 12 is closed, and the mark 17 provided on the container 12. Means that the lid 14 has been removed, that is, the container 12 has been opened. Further, the marks 21, 22, and 23 provided on the attachment member 19 and the attachment 20 have a larger number of strokes of the marks 21, 22, and 23 as the attachment 20 becomes longer. By doing so, the meanings of the marks 16, 17, 21, 22, and 23 can be easily remembered.

  The percussion instrument 1 of the present invention can accommodate a plurality of attachments 20 in the body part 5 or in the container 12. For this reason, it is easy to reduce the load during transportation.

  The present invention is not limited to two openings. One opening may be used, and the body 5 may be struck to make a sound, or three or more openings may be provided. Furthermore, this invention does not limit the trunk | drum 5 to resin. For example, it may be wooden.
