What is what does natural mean in music?

In music, the word 'natural' is used to refer to a specific musical note that is neither sharp nor flat. When a note is referred to as 'natural', it means that it will be played at its normal pitch without any alteration. This is usually because the note has been previously altered by being sharp or flat in a key signature or in a previous measure.

For example, if a song is written in the key of G Major, there are F-sharps in the key signature, which means that every time an F is played, it should be played as an F-sharp, unless indicated otherwise by an accidental. If a note, such as F, does not have a sharp or flat symbol next to it, it is considered 'natural' and should be played at its normal pitch.

In summary, 'natural' in music means to play or sing a note without altering it from its standard pitch.
