I would assume Old MacDonald is one of the main characters. After all, it's his farm in the story.
Well, Old MacDonald is bound to be a central figure in this story. He is the one who owns the farm and is associated with all the activities and sounds there. Additionally, the animals such as the hens that cluck, the horses that neigh, and the sheep that baa are also likely to be main characters in the sense that they are the ones creating all the wonderful sounds that are part of the 'the story of old macdonald sound story'.
Old MacDonald is likely to be the main character, since his name is in the title.
I'm not entirely sure as I haven't read or heard it specifically. But it might be about the adventures or daily life on Old MacDonald's farm, with all the animal sounds that are so characteristic of the Old MacDonald song.
The 'the story of old macdonald golden sound story' could potentially be about the adventures of Old MacDonald on his farm, but with a focus on some sort of golden or special sound. Maybe there's a magical instrument on the farm that makes this golden sound, like a golden flute that the animals are attracted to. Or it could be about Old MacDonald's own voice being a golden sound that soothes the animals and helps them work together on the farm.
The main character is obviously Old MacDonald. And then there are the animals on his farm, like cows, pigs, chickens, ducks etc. These animals play important roles as they are what make up the life on the farm in the story.
Sadly, I have no idea who the creator of the 'old macdonald had a dragon story' is. It could be a relatively unknown individual who just thought it would be fun to merge the traditional Old MacDonald idea with a dragon. Maybe it started as a bedtime story told by a parent to their child and then spread within a family or a small group of friends before being shared more widely, but without any clear indication of its original creator.
There are a few key characters in the Sound of Music story. Maria is the most important one. She is full of life and love for music. Then there's Captain von Trapp, a strict but kind - hearted man. And of course, the von Trapp children, whose lives are changed by Maria. There are also some other characters like the nuns from Maria's convent who play a part in the story at the beginning.
Often, private investigators are the main characters.
I'm not sure exactly as the details about the story aren't fully given. But perhaps there could be a lonely wanderer who is constantly surrounded by silence and has to face it. This character would be one of the main ones.
The main characters would be the little mermaid, who is the central figure of the story. Then there's the sea witch, who plays a crucial role as she gives the little mermaid the means to go on land but at a great cost. Also, the prince, with whom the little mermaid has a fateful encounter and falls in love. There might also be the little mermaid's sisters, who could be important as they might be part of the backstory or try to help the little mermaid in some way.
The safari guide is also an important character. He is in charge of leading Eckels and the others during their time - travel safari. He warns Eckels about the rules and the importance of not changing anything in the past, but unfortunately, Eckels doesn't fully listen. And there are probably other characters in the group who are on the time - traveling trip with Eckels, though they may not be as prominently featured as Eckels and the guide.
