Gamut

Gamut, a name for the musical scale—see MUSIC, SCALE (MUSICAL). Guido of Arezzo, in the 11th century, marked the last of the series of notes in his musical notation with a g or the Greek letter $\backslash gamma$ (gamma), the name of which came to be used for the whole scale—often in a French form gamme. Gamut is compounded of this word and ut, the beginning of a Latin hymn used in singing the scale. See SOLFEGGIO.
