The 4 of C is F
The 4 (four) of C is F: a perfect fourth above the root.
C — the root, 1F — the 4
How to find it
Count letters first, the root included: C, D, E, F. A 4th lands on F.
Then the sound: a perfect fourth is 5 semitones above C, which is exactly where F is — no sharp or flat needed.
Where you meet it
The 4 sits a half step above the major 3rd. In a sus chord it takes the 3rd's place; an octave up it is the 11.
