Why do we need to write music in different key signature?​

In music notation, the key signature tells the reader which notes to play sharp or flat throughout the music. If you are playing a song in a certain key, the same notes will be sharp or flat throughout the entire song. ... That means every F and C you encounter in the music are to be played as Fand C.
