Richard Strauss once wondered about Mahler, to his face I believe, ‘Why don’t you write an opera? You could write such a good opera since you’ve put on so many at the Wiener Staatsoper.’ He didn’t understand and Mahler got pretty angry. In a way Mahler’s symphonies are operas without singers, a sort of total art, in a subjective sense — if that term doesn’t require total sensory stimulation — with vivid use of color and articulate deep expression. The level of abstraction attained by giving up words and human voices enabled him to express more faithfully what really gripped him. The Ninth, like all good symphonies, even more so for Mahler’s but especially in his Ninth, it is a multitude of contents, often all at the same time — ambiguity and paradox seem easily expressed, even refined in Mahler. Vladimir Ashkenazy’s and each of the instrumentalists’ attention and care for each melody, theme, chord and layer in the music make this so clear even as the complexity of the music seems to nourish them; they generously create something fascinating and consoling to listen to — in fact partly because of its complexity it sticks with the listener long afterward.
