E (musical note)

${ \new Staff \with{ \magnifyStaff #3/2 } << \time 2/1 \override Score.TimeSignature #'stencil = ##f { \clef bass e1_E \clef treble e' } >> }$

E is the third note and the fifth semitone of the C major scale, and mi in fixed-do solfège. It has enharmonic equivalents of F♭ [(F-flat) which is by definition a diatonic semitone above E♭] and D (D-double sharp), amongst others.

When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of Middle E (E₄) is approximately 329.628 Hz.^[1] See pitch (music) for a discussion of historical variations in frequency.

F-flat

F♭ is a common enharmonic equivalent of E, but is not regarded as the same note. F♭ is commonly found after E♭ in the same measure in pieces where E♭ is in the key signature, in order to represent a diatonic, rather than a chromatic semitone; writing an E♭ with a following E♮ is regarded as a chromatic alteration of one scale degree.
