E♭ (musical note)

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. 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.

Well-known compositions in E-flat major

The prelude to Richard Wagner's Das Rheingold is a famous piece of drone music that begin with a low E flat and builds to more and more elaborate figurations of the chord of E flat major. It is used in this opera to portray the motion of the river Rhine.[1]

Beethoven's Piano Concerto No. 5 (also known as The Emperor) and Symphony No. 3 (also known as the Eroica) are two more well-known piece set in the key of E-flat major. Robert Schumann's Symphony No. 3 (also known as the Rhenish Symphony) is yet another.

Jimi Hendrix's Voodoo Chile is a well-known popular music piece commonly performed in E-flat major.
