Kill This Love

The harmony in 'Kill This Love' is deliberately functional and static — a four-chord minor loop that the production team weaponizes through texture, timbre, and dynamics rather than chord substitutions or modulation. The military percussion, blaring brass section, and trap-style hi-hats shoulder the emotional escalation, leaving the chord progression as a stable foundation. The song's force comes entirely from arrangement, not harmonic complexity.

YG Entertainment CEO Yang Hyun-suk announced in February 2019 that BLACKPINK was preparing a comeback EP. The lead single was written by Teddy Park and Bekuh Boom — the same songwriting duo behind BLACKPINK's 2018 track 'Ddu-Du Ddu-Du' — with production shared between Teddy, R.Tee, and 24. The song assigns each member a defined vocal role that escalates from the restrained pre-choruses, where Rosé and Jisoo lead the build, to a collective chorus that frames ending the relationship as an act of strength rather than defeat.

Released on April 4, 2019, 'Kill This Love' turned a toxic relationship into stadium-ready spectacle — blaring horns, trap percussion, and four distinct voices converging on a collective declaration of freedom. Written by Teddy Park and Bekuh Boom and produced alongside R.Tee and 24, the lead single from BLACKPINK's second EP hit #1 on Billboard World Digital Songs and entered national charts in 27 countries. The music video, directed by Seo Hyun-seung, broke the YouTube record for most views in 24 hours with 56.7 million.
