He is the technician who created the piano voice that Knize falls in love with and is haunted by when she plays a Grotrian grand Marc prepared for Beethoven Pianos in New York, and he becomes her guide throughout her "odyssey." “At the touch of the keys, I am swept away by powerful waves of sound," the author writes of playing a piano voiced by Marc Wienert. "The treble is bell-like and sparkling, full of color, a shimmering northern lights. The middle section is smoky and mysterious, as if rising from the larynx of a great contralto. A soul seems to reside in the belly of this piano, and it reaches out to touch mine, igniting a spark of desire that quickly catches fire.”
