The organ is an entire “factory complex” of sound. The largest church organs have 10,000+ pipes of various sizes (from a pencil to a several-meter trunk), multiple manuals (keyboards), a pedal keyboard for the feet, and hundreds of stops that alter timbre — from flute-like to “archangel's trumpet.”
The golden age of the organ was the Baroque. J.S. Bach is the greatest organist-composer; his toccatas, preludes, fugues, and chorale preludes remain the pinnacle of the genre. In Ukraine, the organ tradition thrives in Lviv (notably at the Dominican Church's “Evenings of Living Music”), Kyiv (the National House of Organ and Chamber Music of Ukraine), as well as in Odesa, Kharkiv, and Ivano-Frankivsk.
