His first 'idol' was guitarist Kotaro Oshio, from whom he developed an interest in fingerstyle guitar. Jung came to play fingerstyle when his father discovered the technique on the internet. When he struggled he would study online videos. Jung's father taught him the basics, and after learning the basics, he developed his skill greatly just by trying to play what he heard. He found his father's guitar playing more interesting than piano, which he was already learning.

Jung developed an interest in guitar after watching his father play. Sungha Jung at the Musikmesse Frankfurt 2016
