The pipe organ at Ark Hall with a charm of affluent sound

MUSE provides you with many opportunities to enjoy the wonderful timbre of pipe organ, including organ recitals by Japanese and overseas organists, their concerting with orchestras, and Christmas concerts. Please come and enjoy the sound of “the King of Instrument, pipe organ” at Ark Hall.

“The pipe organ in its timbre and sound naturally expresses the individuality of the Hall. The Ark Hall is abundant with warmth of wood. Therefore, its pipe organ has a rich and longer sound with full of warmth.” The MUSE adviser and worldly active organist Naomi Matsui talked of the charm of the pipe organ at Ark Hall. The various sound and timbre of the “King of Instruments,” pipe organ, is produced in the combination of stops.

The original timbre producted in the combination of stops

The Ark Hall's pipe organ has 75 stops. Each organist produces one's original timbre with combining these stops, and it is said that some organists keep secret how he/she combines the stops until his/her performance has started.Thus, the timbre of pipe organ varies with the combination of stops. On each stop, its name, assigned keyboard, feet pitch, and number are described. The organist, reading the descriptions, decides the combination of stops for performance. The computer is installed in the pipe organ at Ark Hall to memorise the stops' combination. Therefore, the organist is able to reproduce the pre-set combination by pressing a button. The Ark Hall pipe organ is manufactured by the world-renowned Rieger Company of Austria, who undertakes world-wide organ projects including the new organ of the Stephan Cathedral in Vienna, after one and a half year of work. The Ark Hall organ is the brother instrument to the one at Suntory Hall in Japan. Having two Swell keyboards, each of which have French and German symphonic sound, and equipped with 75 stops and 5563 pipes, the Ark Hall pipe organ is prominently one of the largest instruments in Japan.

The pipe organ consists of the console with keyboards and pedals (foot keyboards), and stops, the pipes in various sizes that make actual sounds, and the motor and the wind box that accumulates wind, both placed hidden.
