The Polytechnic University of the Philippines Laboratory High School Chorale was formally established in 2003 by a PNU graduate, Mr. Jonathan A. Jarin.

The group sang for the monthly catholic masses at the PUP Interfaith Chapel and the school's programs until they joined Rotary Club of Makati's “Touch Another Filipino Soul” District Youth Choral Competition in 2005.
