These Tres Impromptus for solo piano, previously unpublished, and for which Montsalvatge won a prize in a music competition organized by the Concepció Rabell i Civils Foundation in 1933, have only recently been found in the library of the Orfeó Català. At the time Xavier Montsalvatge was in his early twenties and his prize money amounted to five hundred pesetas.These scores, which Tritó will soon publish, expand our catalogue of piano works by Montsalvatge, which already includes outstanding titles such as Bressoleig, Quatre diàlegs amb el piano, Alborada en Aurinx and Concerto del Albaicín.
