WHAT started as a pleasure for Canadian singer Sarah McLachlan became a powerful campaign that changed the role of women in music.

You might call them an early celebrity couple: young, famous, desperately in love, and doomed. Their story of defying the odds to live together happily – but not ever after, or even for long – might have made a gripping Puccini opera. It was irresistible for Hollywood, whose schmaltzy treatment of Robert and Clara Schumann you can guess from the 1947 title Song of Love.

It was announced today, Monday, April 12, that ASCAP composer Jennifer Higdon has won the 2010 Pulitzer Prize in Music. The Pulitzer jury awarded Higdon’s “Violin Concerto” (Lawdon Press), “a deeply engaging piece that combines flowing lyricism with dazzling virtuosity.” The piece premiered on February 6, 2009, in Indianapolis, Indiana.

Smarting from his rejection by British orchestras, the conductor Alex Prior went off to conduct the Seattle Symphony Orchestra in January, having beaten 180 applicants for the post. Nothing too remarkable about that until you realise he is 17 and travelled there with his mother.

Vienna, which never accepted him as one of its own, is paying homage to Gustav Mahler. As head of the opera from 1897 to 1907, Mahler had outraged the city by denouncing its traditions as mere laziness. When he was conductor of the Vienna Philharmonic Orchestra, he updated Beethoven’s scores. As a composer, he unsettled audiences with subversive symphonies of painful ambiguity.

At 16, he was ‘the pianistic find of the century’. There followed a sparkling two decades before his right hand seized up mysteriously. Now, after a 40-year battle to regain mastery of the keyboard, Leon Fleisher is headlining next month’s Aldeburgh Festival. Lynne Walker hears his extraordinary story.

When I was asked 12 months ago by the BBC if I’d be interested in making a film on Henryk Górecki (in Poland) and Arvo Pärt (in Estonia) for their Sacred Music series, I said yes, almost immediately. I’d been very impressed by the first series and liked the idea pairing of two composers writing religious music in the communist Eastern Bloc who have become almost cult figures in our secular age.

Australians played an important role in bringing to life a rare new symphony from Arvo Part, writes Harriet Cunningham. Silence. It has been a recurring theme in the life and music of one of the world’s most revered composers, Arvo Part.

If there’s one reason why Samuel Barber should have lived to be 100, it’s the upside-down irony that his monumental New York flop is Philadelphia’s hottest opera ticket.
