Have you ever seen a musical on stage? It's the type of show where people sing and dance around while telling a story. Well, a very long time ago, people didn't have musicals like we do today.
In fact, musical theatre as we know it now started with operas. Operas were like musicals but usually, they were in a different language, and the stories were more serious. The actors would sing all their lines, and there would be no spoken dialogue.
Then, in the early 1900s, people started to change from operas to something new called "musical comedy." This is where comedy was added to the show, and the stories became lighter. And they started to use more spoken dialogue and more songs were added that people could understand and sing along to.
Musical theatre continued to evolve throughout the 20th century. There were famous musicals like "Oklahoma!" and "West Side Story." These shows had big song and dance numbers, and the stories were much easier to understand.
As time passed, musicals started getting even more elaborate, with big sets and high tech. Today, you can see musicals with amazing special effects, fancy costumes, and even more amazing songs and dance numbers.
So, in a nutshell, musical theatre developed from operas to musical comedies, and has continued to evolve with bigger and better performances over time.
