Herman Scherchen, the distinguished German conductor, says in his Handbook of Conducting, “The alto trombone: Every orchestra should possess one of these; it is, even nowadays, indispensable for performing Mendelssohn’s ‘Ruy Blas’ Overture; Schumann’s E flat major Symphony; ‘Rienzi’; ‘La Muette de Portici’; and Bach’s ‘Art of Fugue’ in Wolfgang Gräser’s arrangement” (Scherchen 102).
