In 'Doctor Zhivago,' the quote 'The personal life is dead in Russia' underscores the tragedy of the revolution. The film's legendary 'Lara's Theme' is carried by the balalaika. The balalaika is a Russian stringed instrument with a characteristic triangular body and three strings. Composer Maurice Jarre initially struggled to find balalaika players in the West who could play the romantic melody. He eventually located a group of elderly Russian immigrants in Los Angeles who had not played professionally in years. Their performance gave the film an authentic, nostalgic soul. The shimmering, tremolo sound of the balalaika became a global movie legend, proving that a folk instrument with a unique shape can become the emotional heart of a massive historical epic and its most poetic dialogue.
