In the winter and spring of 1893, while in New York, Dvořák wrote his most popular work, the "Symphony No.9, "From the New World"". He spent the summer of 1893 with his family in the Czech-speaking community of Spillville, Iowa, where some of his cousins lived. He also composed chamber music there, including a String Quartet in F which is known as the “American”, and a Sonatina for Violin and Piano.
