Himig Undaya is the official alumnae choir of the St. Theresa’s College Quezon City Alumnae Association under the tutelege of its conductor, music and artistic director, Jai Sabas-Aracama. The choral group consists of members from different alumnae batches who came together for their love of singing and of music, acting as ambassadors of goodwill for the Theresian alumnae community. Founded in 2018, Himig Undaya’s name is inspired from the legendary warrior, Princess Urduja, (a variation of Udaya) who lived in the 14th century in the Kingdom of Tawalisi, now known as Pangasinan.
