The present invention relates to a xylophone in use for learning comprising: a plurality of resonators having a rectangular section having different sizes; sound-absorbing holes formed on the middle of an upper surface of the resonators; a plurality of sound bars installed above the resonators respectively to be assembled and installed one by one to maintain a certain height above the sound-absorbing holes, generating sound tuned to scale; and a main body of a portable case having resonators, which have the sound bars tuned to the scale assembled one by one, mounted by size to be able to be inserted and separated. Supporting protrusion parts protrude downwards from the bottoms of the upper parts of the resonators in a longitudinal direction of the resonators to traverse the sound-absorbing hole. A plurality of sponge mounting grooves to mount rubber sponge are formed on both sides of the sound-absorbing hole to support the sound bars. Pin assembly holes having metallic assembly pins to assemble the sound bars inserted therein are formed on one side of each of the sponge mounting grooves. The pin assembly holes are formed from the upper surface of the resonators into a depth of the supporting protrusion parts. The metallic assembly pins penetrating attachment holes formed on both sides of the sound bars are firmly inserted using force. |
