[Machine Translation] The work consists of 24 preludes and fugues in all major and minor keys, and is a masterpiece that explores all the possibilities of the new tuning system of the average. Leonhardt's intelligent approach and insightful performance, which led Bruchen to say, "He is the Bach of our time," bring Bach's spirit vividly to life in the present. Leonhardt's approach, in which the performers do not stand out, but rather the works themselves assert their existence, is a true pursuit of the sound that Bach would have wanted, bringing out the essential appeal of the works and evoking deep emotions in the listeners. Leonhardt's only recording of the complete works was highly acclaimed as a supreme masterpiece on harpsichord, and was awarded the Edison Prize of the Netherlands. Recorded in 1972, 1973, and 1976 at the Itosugi Room, Huger Castle, Kirchheim, Germany.
