This song features vocals from British Virgin Islands singer Iyaz, was written by Niclas Molinder, Joacim Persson, Johan Alkenäs and R&B singer-songwriter Lyrica Anderson, and produced by Twin and Alke. A remix was said to be released on iTunes on February 16, 2010 which was later changed to February 23, the same day as the release of the album version. But the album version was delayed and was released on March 2. It is Charice's first number one single. Pyramid is a midtempo pop ballad with lyrics that metaphorically describes the strength of a relationship. "Pyramid" peaked at the Billboard Hot 100 chart at number 56, making Charice the second Filipino singer to enter the chart since Jaya's debut single "If You Leave Me Now" peaked on the Billboard Hot 100 at number 44 in 1990.

Pyramid had already received airplay before it was released to iTunes. It aired on 104.3 in Las Vegas before its release as a single. The album version was released to U.S. mainstream radio on March 15, 2010. It is her first single to achieve mainstream airplay. The song was sung in Simlish for The Sims 3: Ambitions, an expansion pack for the strategic life simulation computer game, The Sims 3.

Charice's first live performance was on The Oprah Winfrey Show with Iyaz on May 11, 2010. She also performed it on QVC with her other songs from her self-titled album, Charice such as "I Love You", "Note to God" and "In This Song".
