playReady

When I was in college studying classical music, I heard someone in the practice room next to me playing the same Brahms sonata—but playing it better than me. It was one of those moments where I was like, “Well, I’m not gonna be the best Brahms Interpreter.” But I can be the best interpreter of my music. That’s what I strive for.
