First experience with Cajon drums --- On a sunny weekend afternoon, everyone gathered in the music classroom to learn how to play the Cajon drum, beating the drums in lively synchronicity to the rhythm of the music. The editor feels that music is a part of human nature; seeing their happy smiles made all the effort worthwhile. The editor would like to thank Teacher Chen Guo-Tai for his humorous, friendly and professional instruction. After this lesson, everyone became highly interested in the Cajon drum.
