Carnivals, also known as "carnivals", are usually grand events with a theme of celebration and entertainment, and may include a variety of rides, food, games, shows and exhibitions. These events are usually held in a specific location, such as an amusement park, town square, or resort area. Carnivals usually feature musical performances, dancing, circus acts, magic shows, etc. as the main entertainment element, but may also include other forms of entertainment.
A music festival, on the other hand, is an event featuring musical performances, usually by a group of musicians or bands performing live at a specific location. The program of a music festival may include different types of music such as rock, pop, jazz, classical, and so on. Unlike carnivals, music festivals focus on musical performances rather than other elements of entertainment.
Of course, some places host events that combine the features of a carnival and a music festival. These events may include rides, food, and a variety of performances, while also focusing on musical performances. Such events are often referred to as "carnival festivals" or "music festival carnivals".
Overall, the main difference between carnivals and music festivals is their main focus and content. Carnivals focus more on the diversity of entertainment elements, while music festivals focus on live music performances.
