D
[1] is a
musical note a
whole tone above
C, and is known as Re within the
fixed-Do solfege system. Its
enharmonic equivalents are C
(C-double sharp) and E
(E-double flat). It is the third 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 (D4) is approximately 293.665Hz. [2] See pitch for a discussion of historical variations in frequency.
