Jazz melodic minor

E sharp

E (Ger. Eis) is a common enharmonic equivalent of F, but is not regarded as the same note. E is commonly found before F in the same measure in pieces where F is in the key signature, in order to represent a diatonic, rather than a chromatic semitone; writing an F with a following F is regarded as a chromatic alteration of one scale degree. Though E and F sound the same in any 12-tone temperament, other tunings may define them as distinct pitches.
