I'm not entirely sure as I haven't read it in a while, but usually in a story about a singing lesson, there would be a teacher and a student as main characters.
I think the theme is related to the transformation. Maybe the characters in 'The Singing Lesson' experience some kind of change during the singing lesson. It could be a change in their perspective, mood, or relationship with others.
One possible moral could be about the value of freedom. The singing bird represents freedom and its song is a symbol of the beauty that comes with it. The king, who may have a lot of power but perhaps lacks the freedom of spirit, could learn from the bird that freedom is precious.
The story might be about a singing lesson. Maybe it involves a student learning to sing, facing challenges like hitting the right notes or controlling their voice. There could also be a teacher guiding the student through different techniques.
In 'the singing lesson full story', the first key element is the motivation of the person taking the lesson. It could be a dream to sing on a big stage or just a hobby. Then, the teaching methods used by the instructor are important. Are they traditional or modern? The progress of the student throughout the lesson is also a significant element. Does the student overcome their initial difficulties? And finally, the overall atmosphere of the lesson, whether it's strict and formal or relaxed and friendly, also plays a part in shaping the story.
It could be that the lesson is to not judge people based on their appearance or background. There might also be a message about the value of hard work and determination.
I haven't actually read the 'Singing on a Star' short story, so I can't provide a detailed analysis. But generally, when analyzing a short story, one could start with the characters. Who are the main characters? What are their personalities and motives? Another aspect could be the plot. Is it a linear plot or does it have twists and turns? Also, the setting of the story, like where and when it takes place, can greatly influence the overall mood and theme.
