F♭is a commonenharmonicequivalent 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 thekey signature,in order to represent adiatonic,rather than a chromatic semitone; writing an E♭with a following E♮is regarded as a chromatic alteration of one scale degree.
