Founder | Music Instructor | Academic Instructor
Barry Felder has been an active performer and teacher in the Washington, D.C. area for the past 25 years. He founded Cornerstone Music, Art & Learning in 2010. His goal is to ignite a passion for lifelong learning in the students, and empower them to teach themselves anything they want.
In Barry's studio, students can be heard playing everything from Bach, Beethoven, Rachmaninoff and Chopin, to Psy, LMFAO, Super Mario, and Bollywood. His personal approach to teaching music emphasizes a thorough grounding in the fundamentals along with a healthy dose of fun and a little craziness!
