GAMUT, GAM-ut, in Music, a scale wherein we may learn to found the musical notes, ut, re, mi, fa, sol, la, in their several orders and dispositions. See Music.

The invention of this scale is owing to Guido Arezzo, a monk of Arezzo, in Tuscany, about the year 1099; though it is not so properly an invention, as an improvement on the diagram or scale of the ancients. See AREZIO.

Several alterations have been made in the gammut. M. Le Maire, particularly, has added a seventh note; viz. \( f \); and the English usually throw out both \( ut \) and \( f \), and make the other five serve for all.
