Today I had an illuminating little conversation with a customer. He happened to be holding this book, so I asked him about it. He said he reads the musical notation as he listens to Beethoven. He does it to sharpen his sight reading skills.
"Does it work?" I asked, somewhat stunned at the serendipity of the moment. I told him I'm learning music.
He shrugged. "A little bit, but you still have to put in the hard work. There are no shortcuts."
I must have looked disappointed, because then he laughed.
