Storytelling is when people tell stories. They sometimes add acting or change little parts to make it better. People from different places have their own stories. These stories can be for fun, for learning, for keeping culture, or for teaching good behavior. There are important parts of a story like the plot, the characters, and who is telling the story. Long ago, before people wrote things down, they told stories by talking and using their hands and faces to express themselves. Stories were important in old times, especially in religious events. Some think that old paintings on rocks were ways to tell stories. In Australia, the Aboriginal people made symbols on walls that helped them remember stories. They used talking, music, art, and dance to tell these stories. People also wrote stories on trees, in the sand, leaves, or even with tattoos to show their family stories or what group they belong to. Many stories from all over the world are similar, which might mean that all humans like certain kinds of stories. Some stories, like fairy tales, were so liked that they spread from one place to another. Over time, some stories that were told by mouth became big groups of stories, like the "Arabian Nights", or they were about great heroes.

In music, we hear the same sounds or parts more than once. This is called repetition, and it is very important for music. It helps to make the music sound nice and helps people remember the song. Sometimes, musicians tell us they will repeat parts by using special signs or words in their music. Repeating parts of music can help to make songs feel strong and easy to follow, like a drum that keeps a steady beat. But if musicians repeat too much, it can become boring. We need our memory to enjoy music because we like to remember tunes and think about them. When music repeats, it makes us happy and helps us not to forget the song. Some people think repetition is not good, but others believe it makes music that everyone can enjoy. Music has different amounts of repetition, so every song is unique.
