Vladimir Stasov
During 1875 Borodin started his First String Quartet, much to the displeasure of Mussorgsky and Vladimir Stasov; the other members of The Five were known to be hostile to chamber music. The First Quartet demonstrates mastery of the string quartet form. Borodin's Second Quartet, written in 1881, displays strong lyricism, as in the third movement's popular "Nocturne." While the First Quartet is richer in changes of mood, the Second Quartet has a more uniform atmosphere and expression.
