Answer:
The first dedicated and commercially issued music score was featured in the Walt Disney animated film Snow White and the Seven Dwarfs which was released in 1937.
Explanation
A dedicated music score (also referred to as a film score) is original music (or collection of specially composed songs and soundtracks) customised for a movie. They are usually designed to start and end with scenes within the movie. The purpose of a music score is that it adds life to the film and can be used to enhance visual and dramatic effects.
For example, a scene which features the recall of the loss of a loved one is best accompanied by a solemn or melancholic song.
