The present invention relates to a janggu for practice and, more specifically, to a janggu for practice which makes a user to practice a janggu before playing an actual janggu and capable of shaping a janggu by putting air in the janngu when in use and minimizing volume by removing air when not in use. The present invention includes: a vibrating part (11) which is made of a flexible synthetic resin and which shrinks or expands to be a janggu shape depending on a condition of injecting or discharging air through a valve (11a) provided in the body; and percussion parts (12) which are provided on both sides of the vibrating part (11) to be integrated with the vibrating part (11) or not and which generates high-pitched tone and low-pitched tone resulted from difference in thickness. The present invention shrinks and expands to have a janggu shape depending on whether air is injected into or discharged from the body of the janggu (10), thereby being used after forming a janggu shape by injecting air when in use and being stored by discharging air when not in use. Therefore, the janggu for practice sensuously can obtain performance technical skill while feeling like playing an actual janggu in janggu lesson and can store multiple janggus in the minimum space by minimizing volume when stored. |
