Question: The composer of Allegro de concert was originally from which country?
Sentence (from "Allegro de concert (Chopin)"): It has a curious place in the Chopin canon, and while its history is obscure, the evidence supports the view, shared by Robert Schumann and others, that it started out as the first movement of a projected third piano concerto, of which the orchestral parts are either now non-existent or were never scored at all.
Relevant evidence: No
