Chopin's output as a composer throughout this period declined in quantity year by year. Whereas in 1841 he had written a dozen works, only six were written in 1842 and six shorter pieces in 1843.

Input: Mandolin
At the very end of the 19th century, a new style, with a carved top and back construction inspired by violin family instruments began to supplant the European-style bowl-back instruments in the United States. This new style is credited to mandolins designed and built by Orville Gibson, a Kalamazoo, Michigan luthier who founded the "Gibson Mandolin-Guitar Manufacturing Co., Limited" in 1902. Gibson mandolins evolved into two basic styles: the Florentine or F-style, which has a decorative scroll near the neck, two points on the lower body and usually a scroll carved into the headstock; and the A-style, which is pear shaped, has no points and usually has a simpler headstock.

What sytle did the new style of mandolins supplant?
Output:
European-style bowl-back
