Brothers Rey and Tag Cantong started the band. Rey is the lead singer and guitarist, while Tag plays drums. Rey met singer Kaye Malana at a gig where she performed onstage. Rey Cantong explained the name "Six Part Invention" comes from their musical setup. The band had four members but used a sequencer for extra sounds. They counted the sequencer as two parts. The four members plus the two digital parts equaled six. The title refers to the music, as the songs were written in the key of D or related keys. Rey Cantong wrote and arranged the tracks. Rey Cantong also arranges music for the TV shows
ASAP and ''
It's Showtime''. In October 2025, Six Part Invention released the single "Wasak na Puso" under
Star Music. Rey Cantong wrote and produced the track. The music video featured BINI member Gwen Apuli. The video tells the story of an
Overseas Filipino Worker (OFW) father separated from his children. == Members ==
