The line that goes through middle C on the musical staff is called the "ledger line." In the treble clef, middle C is typically notated on a ledger line below the staff, while in the bass clef, it is notated on a ledger line above the staff. Ledger lines extend the staff to accommodate notes that fall outside its range.
It was a line in a song from a 1942 American musical film called The Yanks Are Coming.
The note that has a line is called a "staff note," which is a musical note placed on the lines of a musical staff. Each line and space on the staff represents a different pitch. The lines on the staff help musicians read and interpret the music accurately. In Western music notation, there are five lines on the staff, each corresponding to specific musical notes.

The line through middle C is called a "ledger line." Ledger lines are used in musical notation to extend the staff for notes that fall above or below it. Middle C itself is positioned on the first ledger line below the treble staff or the first ledger line above the bass staff.
