Some of the greatest music was never completed. Both Schubert and Mahler died before they finished their final symphonies and yet neither work sounds incomplete. There is nothing short-changed about the two movements that Schubert must have realised were perfect as they stood. And Deryck Cooke’s performing version of Mahler’s Tenth Symphony allows us to hear this piece as the composer left it. A fragile, autobiographical journey that charts a path through longing and grief towards a conclusion of uplifting acceptance, the truth of which can only come through love.
