First Known Use: 1601 year

Language of Origin: English

Story behind the word: The term 'key signature' originated from the field of music theory and notation, specifically referring to the set of sharp or flat symbols placed at the beginning of a musical staff to indicate the key of the piece.

Evolution of the word: Originally, the concept of key signatures was not standardized in written music until the Baroque period in the 17th century. Prior to this, composers would use accidentals throughout the piece to indicate key changes.
