To enhance the utility and efficiency of the instruction manuals enclosed in danso (a short bamboo flute) as a teaching aid, this study examines the status of its use targeting students who own the danso instruction manuals. By analyzing its contents, the study suggests how to solve the problems found in the contents. First, according to the results of investigating the status of using the instruction manuals, students tended to use the manual to get help with playing danso and used it by their own will. There was no significant difference between the cases where the manual helped learning and the cases where it did not. The helpful parts in learning were fingering and the acquisition of yulmyeong mostly. The reason why the rest parts were not helpful was students had difficulty understanding the contents of the manuals. Next, the contents of the danso instruction manuals were analyzed by classifying them into the names of the parts, fingering, yulmyeong, fingering by yulmyeong, register, how to make sound, playing posture, repertoire, expression, practice, octave division, jeongganbo, and so on. The analysis showed a difference in the forms of marking the contents, the scope of inclusion, ways of writing, and methods of organization for each manual. Also, this study presented the problems revealed in the names of the parts, fingering, yulmyeong, fingering by yulmyeong, register, how to make sound, playing posture, repertoire, expression, practice, octave division, jeongganbo, and so on and solutions for them. Concerning the problems such as typographical errors in the contents, absence of inclusion, and incomplete description and organization, it suggested the direction of supplementation and revision mainly grounded on the contents of music textbooks or danso handbooks. As the instruction manuals enclosed in danso as a teaching aid influence learning considerably, it is needed to pay constant attention to the manuals and also develop discussion on other components and accessaries used in danso learning.
