Cristóbal MarYán was born in Mexico City to a family of Yaqui and Spanish descent. He started playing the piano when he was eight and not long after began composing at twelve. At sixteen, he moved to Hong Kong to attend Li Po Chun United World College on a full scholarship, where he developed various media and musical projects, primarily focusing on social issues. After graduation, he was admitted to New York University Abu Dhabi, where he completed a Bachelor of Arts in Music, graduating with Magna cum Laude. Cristóbal studied composition with Enrico Chapela, Enrique Mendoza, Carlos Guedes, Dimitris Andrikopolous, Mark Suozzo, and Michael Patterson. He also spent a year in New York City studying Composition and Film Scoring at NYU Steinhardt, where he studied orchestration with Justin Dello Joio, and attended a yearlong composer’s forum mediated by Julia Wolfe. Upon his return to Mexico, MarYán joined the Núcleo Integral de Composición in Mexico City, where he has workshopped his latest pieces. In 2017, he was invited to participate in a weekend-long artist intensive with the Bang on a Can All-stars in Abu Dhabi.
