Eric Whitacre

It's not really the done thing to go into fan mode during an interview

You're there to do a job, so keep it professional - no autograph requests, no selfies. On this occasion, however, I'm going to make an exception. Midlife Choirsis, the choir I sing with in Cheltenham, has been learning one of Eric Whitacre's pieces. Would he be kind enough to film a quick message for them? 'Hey gang! Eric Whitacre here!' he beams into my phone. 'Midlife Choirsis-that's the best name I've ever heard! Thank you all so much for performing Seal Lullaby... Why do I get the feeling he might have done this sort of thing once or twice before?

Conveniently, Seal Lullaby is on Home, Voces8's new album of Whitacre's music, about which we've to come to have a chat at Universal's offices in Kings Cross. However, while the Lullaby is indeed a classic example of the short, dreamy pieces that have made the 53-year-old Nevadaborn composer the toast of countless choirs and listeners across the globe, there is a much weightier affair that I want to ask him about. Taking the lion's share of the same disc is The Sacred Veil, a 50-minute work for voices, cello and piano. By far the longest piece he has ever written, it also relives a time of sorrow.

'In my entire career as a composer, The Sacred Veil was a singular experience,' he tells me. 'I always try to be as thoughtful as possible and go as deep as I can into the text and the subject I am writing about - I have an actor friend who always calls me a "method composer" because I have to live something to write about it. However, nothing was quite like writing The Sacred Veil. The parts I found most difficult to set were Julie's own words. I hadn't realised what a good writer she was, and was wholly unprepared for the amount of emotion inside those words. There were times when I was openly weeping at my desk.'
