The relationship between musical and visual expressions represented in Japanese and Korean television commercials is examined. The categories of musical expressions (tempo, loudness, tonality, rhythm, and instrumentation), visual expressions (foreground of visual image, its behavior, and their background), and subject of commercials are analyzed statistically. The combinations of musical and visual expressions in both Japanese and Korean commercials are classified into four types; dynamic, gentle, daily, and anti-daily expressions. The combination of music and motion pictures is considered to be determined by similar principals in both countries. The subjective rating experiments of typical examples of these four-type commercials shows that they are also psychologically dynamic, gentle, daily, and anti-daily.
