David Moser is an American who has lived in China for almost 20 years. Someone listening to him speaking Mandarin, especially for the first time, would never doubt that he was a native Chinese.
Indeed, Moser has a good command of the Chinese language, and he holds a Ph. D. in Sinology from Michigan University. However, at the very beginning of his university studies, Moser's major was actually music, not Chinese. He loved music when he was a boy, and he thought his lifetime career would be composing and playing music.
