“ A famous Russian composer, founder, with Glinka, of the Russian National School of Music. He was the son of a wealthy nobleman in the Government of Tula. Speechless to his sixth year, he early exhibited fondness for music, and was taught the piano at six and violin at eight; his teachers, later, were Sehoberlechner, a pupil of Hummel, in piano, and Zeibich in musical theory and singing. At Saint Petersburg in 1833 he met Glinka, who lent Dargomyzhsky his copy of Dehn's lectures on musical theory, which "he studied through in five months." ”
