If a person has a preconceived notion of what classical music is, he or she might not want to learn about it. This often comes from not having been exposed to a wide variety of music. Those who are exposed to classical music through their education, through concerts, and through radio and public television programs will often find that they enjoy classical music more than they expected to. If a person broadens their definition of what classical music is, for example, including selected film scores, they might find that they are open to it. Another obstacle is lack of musical training - not taking music lessons.Knowledge of music theory helps the listener to appreciate classical music. Being "tone deaf" is another hindrance to studying classical music. In short: hindrances to the study of classical music include: lack of exposure, a preconceived definition of the genre, lack of musical training and/or music theory, and being tone deaf, limit one's motivation to study classical music.
