What is the type of musical composition that was used by the Korean female band Isak N Jiyeon?
Duet A duet is a musical composition for two performers in which the performers have equal importance to the piece, often a composition involving two singers or two pianists. It differs from a harmony, as the performers take turns performing a solo section rather than performing simultaneously. A piece performed by two pianists performing together on the same piano is a "piano duet" or "piano four hands". A piece for two pianists performing together on separate pianos is a "piano duo".
Stellar (South Korean band) Stellar (Hangul: 스텔라, stylized as STELLAR) is a South Korean girl group whose current line-up is composed of Minhee, Hyoeun, Soyoung & Youngheun. Formed in 2011 by The Entertainment Pascal, the group attracted attention as they were initially produced by Eric Mun of the boy band Shinhwa. Following an unsuccessful debut with the single "Rocket Girl" in August 2011, Stellar underwent a line-up change and released "UFO" in February 2012, which fared similarly.
