French composer Francis Poulenc wrote his Sonata for One Piano, Four Hands in 1918 and it was published in London the following year. This edition is based on that 1919 original edition. A teaching/performing edition, the duet has been carefully edited and fingered for performance ease. Measures are numbered for convenient reference, and the primo and secondo parts are on facing pages. Editorial metronome suggestions are included. Poulenc's French instructions appear along with English translations.
