With Mademoiselle, Bruno Monsaingeon offers us—just as he did in Glenn Gould: No, I’m Not at All an Eccentric—the testimony of an exceptionally lucid and fascinating figure: Nadia Boulanger, “Music personified,” according to Paul Valéry. Pianist, conductor, mentor to Stravinsky, and teacher, over nearly seventy years of career she trained an extraordinary number of leading composers, conductors, and performers of the twentieth century, from Gardiner, Markevitch, Barenboim, Glass, Bernstein, and Menuhin to Piazzolla and Quincy Jones. Drawing on materials gathered during conversations with Boulanger in the final six years of her life, Monsaingeon compiles and organizes these interviews to recreate her voice and evoke the presence of the great teacher of teachers. A deeply moving tribute to an admirable figure, immensely influential both for her unquestionable musical gifts and for her unforgettable pedagogical legacy.
