Gammut or Gamut g (hard). It is gamma ut, "ut" being the first word in the
Guido-von-Arrezzo scale of ut, re mi, fa, sol, la. In the eleventh century the
ancient scale was extended a note below the Greek proslambanomy note
(our A), the first space of the bass staff. The new note was termed g (gamma),
and when "ut" was substituted by Arrezzo the "supernumerary" note was called
gamma or ut, or shortly gamm' ut - i.e. "G ut." The gammut, therefore, properly
means the diatonic scale beginning in the bass clef with "G."
