Ursula Mamlock, who emigrated from Germany in 1939, composed 2000 Notes, her most important work for piano solo, in New York. Here she studied and taught composition until she returned to her native city of Berlin in 2006. In 2015 Yu Fujiwara arranged 2000 Notes for three percussionists (xylophone, glockenspiel, vibraphone, and marimbaphone). Ursula Mamlok was unable to attend the world premiere in Basel in January 2016 but heard a performance in Villingen-Schwenningen on 12 April
