Jung received his first guitar at age nine, a very coarse plywood guitar that cost less than $60. Apart from Korean, Jung speaks English, which he studied to be able to communicate during concerts abroad. He has also sung live, such as when he sang ' Falling Slowly' at a concert in Bangkok. In addition to steel-string and classical guitar, he has been recorded playing twelve-string guitar, electric guitar, ukulele, guitarlele, harp ukulele, and piano. In a video, he recommended the 'AllEars method' for those who like his style of guitar playing and want to learn it. He has also been mentored by German guitarist Ulli BГ¶gershausen, who Jung has referred to as his musical inspiration, and from whom he learned much about composing and arranging. Jung has received guitar lessons from Hata Shuji, a well-known Japanese jazz guitarist. Jung has since played on stage with them multiple times.

His cover of 'The Pirates of the Caribbean' theme song, which has over 61 million views on YouTube as of September 2020, made Jung an internet sensation, and his playing caught the attention of world-renowned guitarists, who found his covers of their songs impressive.

Soon after his debut video on the internet, he garnered many supporters, from whom he asked for advice on his playing. After Bundy saw his cover, Jung played with Bundy in tours throughout South Korea and the United States. Trace Bundy found a video of 9-year-old Sungha Jung playing Bundy's version of (Pachelbel's) Canon. At first, Jung's mother and grandmother disapproved of the 'noise' that Jung and his father continuously created, but they came to understand it as his gift. 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.
