This paper provides a preliminary report of a small-scale research examining the effectiveness of a series of Music Appreciation segments of "Pre-school: Learn to Fly"--a locally designed and produced early childhood TV program in Hong Kong. Four aspects of young children's musical development were studied: 1) musical exposure; 2) attention span; 3) response to music; and 4) musical memory. The findings enrich local understanding of early childhood music education and media, and provide more information for the production of the next series from late 2004.
