Scale degrees · D♭ major
The 3 of D♭ is F
The 3 (three) of D♭ (D flat, Db) is F: a major third above the root.
D♭ — the root, 1F — the 3
How to find it
Count letters first, the root included: D, E, F. A 3rd lands on F.
Then the sound: a major third is 4 semitones above D♭, which is exactly where F is — no sharp or flat needed.
Where you meet it
The 3 decides major or minor. With the 7 it is a guide tone: the two notes that say what a chord is.
