1. _Gamma—ut_. 2. _A—re_. 3. _B—mi_. 4. _C—Fa—ut_, because C is _fa_ in the first, and _ut_ in the second hexachord. Consequently, to a mediæval musician, _C—fa—ut_ meant what we would call C, second space bass clef. The following table gives all the Hexachord Scales with the names of the sounds. It is of interest because this system of nomenclature persisted long after the one which gave rise to it was obsolete. { E la { D la sol Super { C sol fa Acute { B♮ mi { B♭ fa { A la mi re { G sol re ut { F fa ut { E la mi Acute { D la sol re Octave { C sol fa ut { B♮ mi { B♭ fa { A la mi re { G sol re ut { F fa ut { E la mi Grave { D sol re Octave { C fa ut { B mi { A re { Γ ut The Hexachords in which the B was flat were called Soft (_Mollis_); those in which B was natural, Hard (_Dura_); the term _mollis_ has been retained in the French word _Bemol_, a flat, and in the German name for a minor key, _Moll_. The word _dura_ (hard) is also retained in the German as a name for the major key _Dur_. When the letters were used as a means of notation, the sound B-flat was indicated by the old form of the letter b, which has been retained as the sign for a flat. This was called B _rotundum_ (round B); when B natural was wanted, a stroke was put on the right side of the ♭, called B _quadratum_ (squared B), the sign to this day for a natural. REFERENCE.
