Hello, I am Teacher Haeseong, a guitar and ukulele instructor. I currently teach guitar and ukulele at guitar academies, after-school programs for elementary and middle schools, and at lifelong learning and cultural centers. Online, I run the "Teacher Haeseong's Basic Acoustic Guitar" class on Class101, where even those with no prior knowledge can learn to play, and I also operate the YouTube channel "Teacher Haeseong Guitar & Ukulele." Having extensive experience teaching many students, I would like to share the joy of the guitar and ukulele through Kookoo!
