Book excerpt: Prolific as a composer, performer, and recording artist, Percy Grainger was an indefatigable writer. This selection of forty-six essays about the production, promotion, and propagation of music is drawn from his over 150 public writings. Their topics range over his own and his friends' compositional plans, piano technique, Free Music', instrumental usage, and his ideas on artistic development in the United States, Australian, and his beloved Nordic lands.
