Tanghalang Nicanor Abelardo or the CCP Main Theater sits 1,815 guests and has four (4) levels: Orchestra, Boxes, Balcony I and II. It is equipped to meet the requirements of large theater productions such as ballets, operas, and musicals. The shape and design of the Main Theater were rigidly controlled by the acoustical requirements.

Acoustical shells are easily assembled for orchestral and choral performances. A split floor orchestra lift forms an integral part of the apron when it is raised to stage level. A brilliant tapestry curtain patterned after the “Genesis” painting of National Artist Hernando R. Ocampo, is among the highlights of the venue. The stage floor is made of Philippine Mahogany wood.
The theatre was named after Nicanor Abelardo, the Father of Philippine Sonata.
