BIOGRAPHY
Lee Ji-hoon is the primary composer and lyricist behind the majority of SEVENTEEN's discography. He began writing music as a trainee and has since accumulated hundreds of writing and production credits across the group's albums. His vocal range — precise, emotionally controlled, capable of both intimate softness and full-belt power — is SEVENTEEN's sonic benchmark. He was named to Forbes Korea's 30 Under 30 for his contribution to the country's music industry.
Music production (his most serious and constant practice), playing piano independently, and a quiet, introverted lifestyle that contrasts with SEVENTEEN's high-energy image.
