 Nadezhda became a musical as well as domestic partner with her husband, much as Clara Schumann had been with her own husband Robert.She was beautiful, capable, strong-willed, and far better trained musically than her husband at the time they married—she had attended the Saint Petersburg Conservatory in the mid-1860s, studying piano with Anton Gerke (one of whose private students was Mussorgsky) and music theory with Nikolai Zaremba, who also taught Tchaikovsky.Nadezhda proved a fine and most demanding critic of her husband's work; her influence over him in musical matters was strong enough for Balakirev and Stasov to wonder whether she was leading him astray from their musical preferences.
