Grant Gayle began his piano studies at the age of nine. He received his classical training from both Eric Boston and Gabriel Sanchez from elementary school onward through high school. While studying civil engineering at the University of Texas at Austin, he continued his studies with the Butler School of Music faculty, and frequently performed in recitals for non-music majors. During this time, he was an active chamber musician, performing regularly in various ensembles within the Engineering Chamber Orchestra of UT Austin. As one of the prize winners at the 2024 PianoTexas Concerto Competition, Grant performed with the Fort Worth Symphony under the baton of the esteemed conductor, Miguel Harth-Bedoya. During the same festival, Grant received a masterclass from 2013 Van Cliburn Competition gold-medalist, Vadym Kholodenko.

In his spare time, Grant enjoys language learning, world travel, tennis, weightlifting, and exploring the works of lesser-known classical composers. A Dallas-Fort Worth native and resident, he has attended every Van Cliburn International Piano Competition since his teenage years, and is a frequent concert-goer to many of the Cliburn concerts. He works as a civil engineer for Brown and Caldwell, where he designs wastewater treatment plant infrastructure.
