F-flat major

F-flat major is a major scale based on F-flat. Its key signature has eight flats.
Its relative minor is D-flat minor, and its parallel minor is F-flat minor, usually replaced by E minor.
Part of Richard Strauss' "Metamorphosen" uses F flat major, which one commentator has called "a bitter enharmonic parody" of the earlier manifestations of E major in the piece.
To make reading and writing music easier, F-flat major is usually written as its enharmonic equivalent of E major.
