Definition: Middle C (C4) is the half-way point on the piano keyboard; the centermost C. Middle C serves as a loose border between notes played with the left hand (bass notes), and notes played with the right (treble notes).

In sheet music, middle C is written on the first ledger line below the treble staff, and above the bass staff (see image).
