D{{music|flat}} (D-flat) is a musical note lying a diatonic semitone above C and a chromatic semitone below D. It is thus enharmonic to C♯ (musical note). In the French solfège it is known as re bémol. It is the second semitone of the solfège.

When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of middle D{{music|flat}} (or D{{music|flat}}4) is approximately 277.183 Hz.{{cite web|last=Suits|first=B.
