F-flat major (or the key of F-flat) is a theoretical key based on F, consisting of the pitches F, G, A, B double flat, C, D, and E. Its key signature has one double flat and six flats.[1]
The F-flat major scale is:

Although F-flat major is usually notated as its enharmonic equivalent of E major, because E major has four sharps only as opposed to F-flat major's eight flats (including the B), F-flat major appears as a secondary key area in several works in flat keys. 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.[2]
Beethoven also used F-flat major in his Piano Sonata No. 31, Op. 110. In the first movement's exposition, the transitional passage between the first and second subjects consists of arpeggiated figuration beginning in A-flat major and modulating to the dominant key of E-flat major. In the recapitulation, the key for this passage is changed to bring the second subject back in A-flat major: the transitional passage appears in a key that would theoretically be F-flat major, but which is notated in E major, presumably because Beethoven judged this easier to read – this key being a major third below the key of the earlier appearance of this passage. Likewise, the second movement (in A-flat major) of Beethoven's Piano Sonata No. 8 (Pathétique) contains six measures of what would theoretically be F-flat major, but notated as E major (keeping the 4-flat key signature of the movement, so every note in the passage has an accidental).
Another example of F-flat major being notated as E major can be found in the Adagio of Haydn's Trio No. 27 in A-flat major. The Finale of Bruckner's Symphony No. 4 employs enharmonic E for F-flat, but its coda employs F-flat directly, with a Phrygian cadence through F-flat onto the tonic.[3] [4] [5]
An example of F-flat major being used directly is in Victor Ewald's Quintet No. 4 in A-flat major (Op. 8), where the entirety of the third movement is notated in this key.[6]
The climax that occurs in the middle of Samuel Barber's Adagio for Strings resolves to F-flat major. The final cadence of John Rutter's setting of Robert Herrick's poem "What Sweeter Music" is in F-flat major.
