1742 French Harpsichord at the Metropolitan Museum of Art, New York - From the curators' comments: "This harpsichord has two sets of unison strings and one set of octave strings. One of the unisons is played from the upper keyboard, and the second unison and the octave are played from the lower keyboard. Pushing the upper keyboard inward couples the keyboards so that all three strings may be played from the lower keyboard."
Leonard Bernstein (1918–1990), was an American composer, conductor, author, music lecturer, and pianist. He was among the first conductors born and educated in the United States of America to receive worldwide acclaim. His fame derived from his long tenure as the music director of the New York Philharmonic, from his conducting of concerts with most of the world's leading orchestras, and from his music for West Side Story, as well as Candide, Wonderful Town, On the Town and his own Mass.
1860 French Accordion at the Metropolitan Museum of Art, New York - From the curators' comments: "In the 1830s, Paris became a major center of accordion production, which flourished until the Franco-Prussian War of 1870-71. To compete with makers in Austria and Germany, Paris manufacturers successfully marketed their instruments by applying rich and costly decoration."
