The harpsichord that was built during the writing of this book was completed in May, 2009. On June 7, 2009, the harpsichord was played in a concert given by Dr. John O'Brien, professor of music, East Carolina University. The instrument is based on the work of Andreas Ruckers, a member of the Rucker's dynasty, that produced instruments that many argue are amongst the finest ever built. Despite its diminutive size, or perhaps because of it, its sound is strong, robust, and aggressive. Listeners expecting to hear a little 'tinkle-box' are taken aback by both the quality and quantity of its sound. In addition to my good fortune in having Dr. O'Brien play it so beautifully, I am equally thankful to have had it recorded so faithfully by Tom Jung of DMP records. To fully appreciate the quality of this recording I urge you to listen to the concert through headphones.
