If only we could hand out those scratch-n-sniff cards to PT listeners today. It might come close to approximating what Manuel de Falla had in mind when he wrote his "Nights in the Gardens of Spain." He meant his music to evoke not just the sights and sounds of the gardens surrounding the Alhambra palace in Granada, Spain. He wanted to conjure up the delicate fragrances of the place that's been called "Paradise on Earth." If you can, find a quiet garden spot, lean back, close your eyes, and inhale de Falla's gorgeous music.
