The organ lecture concert by Jean-Philippe Mercurarts is a valuable opportunity to explore the inside of a pipe organ. In the first half, you can learn concisely about the inside of the organ, which is usually not visible, and its 400 years of history. In the second half, the pieces introduced in the first half are performed, deepening the experience. The event is held at the Nasunogahara Harmony Hall, with convenient access by car or public transportation. General seating is 1,000 yen, and elementary and junior high school students can participate for free. This event is especially recommended for those interested in organs and can be enjoyed by parents and children alike. Be sure to visit and experience the mystery of music.
