During the Middle Ages, the musical staff only had 4 lines, with a movable C clef. It was used for sacred chants in the Catholic church. Being that it was only for voice, with limited range, 4 lines was all that was needed. There were instruments around at the time, but the players generally learned songs by ear (instruments weren't used in church yet). As music eventually became more complex, with wider ranges and multiple voices, a 5th line was added, as well as new clefs. It was easier to switch clefs in a staff rather than add more and more lines.

Staff lines
When you run out of lines on a musical staff, you can use ledger lines. These are short lines added above or below the staff to extend the range of notes that can be notated.
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 musical staff was invented because it would be easier to figure out the different pitches and either it was the bass clef or the treble clef.

In music, a staff is a set of five horizontal lines where musical notes are written. Each line and space on the staff represents a different pitch. Notes are placed on the staff to indicate the pitch and duration of the sound to be played by musicians. The staff is a fundamental part of musical notation, helping musicians read and interpret music accurately.
