The danso (short bamboo flute) is the very first Korean traditional instrument that people encounter and thus the first impression of Korean traditional music. When used in the curriculum, danso has many great advantages. It is very portable, has a tranquil tone, and helps one practice one’s self-control exercise through abdominal breathing, a deep, long breathing skill. Although it is being replaced with the sogeum because it is relatively difficult to make sounds and requires great patience during practice, danso still plays an important role as an introduction to the Korean traditional music. The number of people who can play danso has increased since danso education became part of the school curriculum. However, there is room for reconsideration of whether there has been improvements in quality of danso performance. There are many reasons for this, but one of the main reasons is the importance of the textbook. For danso learning experience in a school environment to carry on into everyday life, the improvement of textbook approachability and development of textbooks for different performance levels are inevitable. This research first examines 44 textbooks out of the various danso music scores and textbooks published after the liberation of Korea, by dividing them into theory, music classification and analysis. Then textbooks with a high ratio of folk songs were selected and compared in a musical, contextual setting. The findings indicated that the section of performing techniques such as fingering, body positioning and how to make sounds and lip shape was generally well described, but there was an insufficient amount of contents as regards with breathing method. As for learning method, learning through different levels of difficulty was proposed, and as for curriculum and textbook connection, it was observed that there was a higher ratio of traditional children’s songs since the 7th Revised National Music Ceducational Curriculum. As for music classification and analysis, levels can be classified into beginner, intermediate and advanced, depending on the level of difficulty of music. What is noteworthy is that Kyonggi folk songs took up a high percentage, and, as a result, there is an imbalance in the weight put on various folk songs. Based on these observations, it is verified that developing danso textbooks for different levels is necessary. Moreover, we propose placing equal amounts of music from various geographic regions, utilizing ensembles and developing separate textbooks for pyeongjol danso and improved danso.
