F-flat major F-flat major F major (or the key of F) is a theoretical key based on F, consisting of the pitches F, G, A, B, C, D, and E Its key signature has six flats and one double flat. The F major scale is: \override Score.TimeSignature #'stencil = ##f \relative c' { </score> Its relative minor is D minor, usually replaced by C minor (see reason below) and its parallel minor is F minor, usually replaced by E minor, since F minor's four double-flats make it generally impractical to use. Because of that, it is usually enharmonic to E major with
Music of Mesopotamia same key signature as a C-major scale. The F-Major scale has a B-flat in the key signature, however with the raised fourth in the lydian scale, the B-flat becomes a B-natural. The drawback in modern music with the lydian scale is the use of what's known today as the "devil's tritone," however, the Mesopotamians don't seem to have a term for this interval, nor a term for the octave which we know they had a concept of. The use of a heptatonic scale would have eliminated any practical need for a term for the octave, as it wouldn't have the
