UBERTI, Giulio, poet, patriot, and teacher of declamation, born 1805. Together with his friends, Modena and Mazzini, by the power of the pen he succeeded in raising the youth of Italy to action against the tyranny of a foreign domination, and to the establishment of the national independence. His poems are noticed at length by Cesare Cantú in his History of Italian Literature. Born at Milan, he lived there the greater portion of his life engaged as a teacher of declamation. He numbered Malibran and Grisi amongst his pupils, and was the last of the masters of declamation who still preserved the old traditions of classical tragic acting. He died by his own hand in 1876, a patriot, but a republican to the end. [J.C.G.]

U. C. (Ital. una corda; Fr. petite pedale; Germ, mit Verschiebung). An indication of the use of the left pedal of the pianoforte, by means of which the action is shifted a little to the right, and the hammers made to strike a single string (in modern instruments generally two strings), instead of the three which are ordinarily struck.
