Singers need to take care of their vocal cords and maintain good vocal health, which can involve practices like warming up before performances, staying hydrated, and avoiding smoking and other harmful habits. They may also need to work with vocal coaches or speech therapists to improve their vocal technique and address any issues that arise. Pop singers typically sing in a more mainstream, commercially appealing style. They often use catchy melodies, simple harmonies, and electronic or synthesized sounds to create upbeat and danceable songs. Some famous pop singers include Taylor Swift, Justin Bieber, Ariana Grande, and Ed Sheeran.
