What was the name of music used at close of radio transmission each night in the years 1960 to 1970?

The music typically used to close radio transmissions each night during the 1960s to 1970 was known as "sign-off music." One of the most famous pieces used for this purpose was "Taps," a military bugle call often associated with the end of the day. Other stations might have used specific thematic songs or jingles unique to their broadcasts, but "Taps" became iconic for its somber and reflective tone.
