To those who grew up with Michael Tippett’s music and lived through the later premières, the neglect into which he has fallen and the ill-disguised contempt of many is both puzzling and distressing. The same fate befell both Sibelius and Vaughan Williams in the years following their deaths and now, fifteen years on, there is perhaps just a faint glimmer of a Tippett reappraisal on the horizon. The BBC Proms have mounted a handsome series of works this year and, although only one work was included in this year’s Presteigne Festival, the festival has consistently kept faith with Tippett. Although less than 20 minutes long, The Heart’s Assurance is a key work and the most personal ever to come from Tippett’s pen. Composed in 1951 for Peter Pears and Benjamin Britten, it forms a neat adjunct to the festival’s Britten performance of Curlew River, which was dedicated to Tippett. Taking texts by Sidney Keyes and Alun Lewis, it was a response to the suicide, in April 1945, of Francesca Allinson, one of Tippett’s closest friends. Writing forty years after its composition in 1990, Tippett remarked, “I am still unutterably moved when I hear it performed”. One can see why: the music has a raw emotional appeal not found anywhere else in his output – be it the almost unbearable transience of the opening song or the leave-taking of the final piece.
Britten remarked, one suspects more in frustration that jest, that he wished Tippett’s piano parts were not so difficult, and The Heart’s Assurance is a minefield for any but the most securely equipped of performers. The essential challenge is to find a clear line through the dense musical text that sounds both inevitable and effortless – qualities that tenor Andrew Tortise and pianist Chris Hopkins seemed to achieve with ease, both here and in the other works on their excellent programme.
