Gamut, Gam-ut, in Music, a scale whereon we may learn to sound 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 Are- tin, a monk of Arezzo, in Tuscany, about the year 1009; though it is not so properly an invention, as an improvement on the diagram or scale of the ancients. See ARETIN.

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.
