Decide which composers, pieces, genres and eras of classical music you will choose to introduce to a person. A good entry point can be music used in the score of one of the person's favorite films. Directors often use classical music in scores to enhance the emotional impact of their images and story lines. Choosing a piece a person may already be familiar with from another context can prove very successful since positive associations can lead to more likely acceptance of the music.
Choose a time and a place for introducing the piece of classical music carefully. Often times, the location can have significance. It is best not to introduce new music to someone in a confined or stressful setting. Choose a setting where the person will feel comfortable. Again, it's a matter of positive associations.
Attend a classical music event, such as a symphony orchestra concert, a chamber concert, a ballet or an opera. Once people become interested in classical music, live performances can greatly enhance their appreciation for the beauty, complexity and emotional impact of the music.
Make a gift of a classical music CD or DVD that you believe the person will enjoy. Giving a gift can be a way to keep the interest level in this music high. Tailor the gift to the person's initial interests and provide recommendations for learning about other composers, pieces and styles.
Recommend a book or several books on classical music to the person. Libraries and well-stocked bookstores are full of histories of classical music, guides to recorded music and biographies of composers and performers. Target your recommendation to the person's initial interests and provide further recommendations as the person's interests in this rich, complex subject expand.
