F-flat

The lowered fourth tone ( subdominant). This pitch has no solfeggio representation because the actual pitch is the same as the mediant or third note ( E) in the fixed do system. However, the note name F-flat is necessary in certain instances such as the key of C-flat major where F-flat is the fourth note ( subdominant), or A-flat minor, where F-flat is the sixth note ( submediant). The frequencies of the audible pitches of F-flat are notated below. See also [Eng.] F-flat; [Fr.] Fa b'mol; [Ger.] Fes; [It.] Fa bemolle; [Sp.] Fa bemol.
