Guy started his piano lessons at the age of 8 with Natalia Blumenfeld at the Israel Conservatory of Music. At the age of 12, he performed with the Israeli Chamber Orchestra. In 2016 he graduated with honors from the Buchmann-Mehta School of Music in Tel Aviv with Professor Asaf Zohar as his piano teacher. In 2018 Guy obtained his Master of Music diploma from the Conservatorium van Amsterdam under the guidance of Naum Grubert.

During his Master's in piano performance, Guy's passion and interest in Early Music and historical keyboard instruments were increasing, which led him to pursue another Master's in harpsichord and fortepiano with Olga Pashchenko, Menno van Delft and Kris Verhelst and at the Conservatorium van Amsterdam.

Guy was granted the Holland scholarship as well as scholarships by the America-Israel Cultural Foundation.
