Final answer:
In 'The Pearl' by John Steinbeck, Kino calls the soft, clear song he hears in his head 'The Song of the Family', which symbolizes the love and security he feels towards his family.
Step-by-step explanation:
The question refers to the character Kino and the soft, clear song he hears in his head, which is called 'The Song of the Family' in John Steinbeck's novel 'The Pearl'. The song represents the sense of love, warmth, and security Kino feels when thinking about his family.
In literature, this type of motif is used to symbolically represent more complex ideas and themes, and Steinbeck uses songs throughout the novel to illustrate Kino's changing feelings and experiences.
