(Guitar). Julio Sagreras was born in Buenos Aires in 1879 to a family of Spanish origins. Both of his parents, Gaspar Sagreras and Dolores Ramirez, were guitarists. From a very young age Julio showed extraordinary musical gifts that made him a guitarist admired and in demand in all the musical salons of the Argentine capital. This edition differs from the previous ones, as well as for a new and more modern musical graphics, for the simplification of the fingerings that Sagreras pedantically repeated even in the most obvious situations, for the correction of errors, the development of more detailed explanations and the addition of some necessary historical and practical clarifications.
