E♭ (E-flat) or mi bémol is the fourth semitone of the solfège.

It lies a diatonic semitone above D and a chromatic semitone below E, thus being enharmonic to D♯ (D-sharp) or re dièse. In equal temperament it is also enharmonic with F (F-double flat). However, in some temperaments, D♯ is not the same as E♭. E♭ is a perfect fourth above B♭, whereas D♯ is a major third above B.

When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the E♭ above middle C (or E♭₄) is approximately 311.127 Hz. See pitch (music) for a discussion of historical variations in frequency.

In German nomenclature, it is known as Es, sometimes (especially in the context of musical motifs, e.g. DSCH motif) abbreviated to S.
