Se7en ‘s vocal range can be classified in the tenor range. His voice can be described as smooth, mellow, and sometimes mildly abrasive (see vocal belting) when songs, such as “Crazy,” “La La La,” “Hikari” and “I Know,” call for it. He often sings with a vibrato in his voice that American R&B singers are known for, and also incorporates beatboxing into many of his songs such as “Passion.” Se7en maintains an adamant belief that he should not lipsync during his live performances.
 Personal life
In June 2009, Se7en acknowledged on his website that he and actress Park Han-byul had been in a relationship for over nine years, with the couple having first met when they were seniors in high school. Se7en had previously denied rumours that they were a couple in order to protect Park’s privacy and let the relationship grow naturally. Han-byul was featured in Se7en’s music video for his song “I’m Going Crazy”.
