The ♭7 of D is C

The ♭7 (flat seven, written b7) of D is C: a minor seventh above the root.

How to find it

Count letters first, the root included: D, E, F, G, A, B, C. A 7th lands on C.

Then the sound: a minor seventh is 10 semitones above D, which is exactly where C is — no sharp or flat needed.
