Metropolitan Music Lab
provides immersive music and audio production education to classrooms, groups, and individual students throughout New York City. Our accelerated and comprehensive courses empower students to achieve true musical and creative independence—quickly and fully. Through a creation-based approach, students learn music theory and core concepts by composing, performing, and recording their own original works. This hands-on process transforms theory into practice, making learning both engaging and deeply personal.
Students learn to write, communicate, and gain practical experience across multiple instruments, voice, chorus, and digital audio production—equipping them with the skills, confidence, and inspiration to become self-sufficient creators in today’s music landscape.
