Tchaikovsky’s musical scores are lyrical, romantic and deeply emotional. This film endeavours to put the composer in context alongside Tolstoy as one of the most celebrated Russians of his time, examining his continuing significance in Russia today, and visiting locations which were important in Tchaikovsky’s life. His life is scoured to reveal an abortive marriage, his true feelings about homosexuality and how this may have been expressed in his music. Contributors include pianists Mikhail Rudy and Yevgeni Kissin, violinist Maxim Vengerov, conductor Valery Gergiev, ballerina Natalia Makarova, opera director Graham Vick and the Tchaikovsky-loving tram driver, Valentina.

Mahler was scarcely recognised as a great composer until the middle of the 1960s, when his music started to make a massive impact. In 1991, thirty recordings of his symphonies were released in one month. This film explores Mahler’s life: his childhood, surrounded by tragedy and abuse; his driven adulthood, torn between life as a composer and conductor, and his passionate and pained love-life. This programme examines his music, the supreme expression of philosophical enquiry in music, embracing religion, hihilism, humanism, the revolutionary and the mundane. Reconstructions, archive footage, radio interviews, artefacts, private scores, letters, contracts and sculptures are used, along with interviews with many prominent artists and writers. The documentary is set in Vienna, Budapest, Hamburg and the Czech Republic.

Puccini is today the most popular of opera composers, but not necessarily the most respected. From humble origins in the town of Lucca in Tuscany, he rose from the Milan conservatoire to compose some of the greatest Italian operas.

Interviewees include Puccini’s grand-daughter Simonetta Puccini, opera producer and actor Simon Callow, experts Julian Budden, William Ashbrook, Leonardo Pinzauti, Alan Sievwright and conductor Sir Charles Mackerras. The programme contains extracts from his operas, sung by José Cura, Leontina Vaduva and Julia Migenes, with conductor Richard Buckley and the BBC Phiharmonic.
