A short piece for two pianos, composed in 1949. Although Auric had previously written one work for this instrumentation (《Les Amours de Livres》), this 《Valse》 is his first published work for two pianos. The score was published in 1955, and the premiere took place even later, on April 21, 1968, at The Pierre Hotel in New York, performed by Arthur Gold and Robert Fizdale.

Following an introduction (8 measures, 12/8 time), it transitions into a waltz in 3/4 time, where the melody is sung leisurely, accompanied by ornamentation in the high register. The melody, marked with tenuto, includes the instruction 'doucement appuyé' (gently pressed). After a middle section that slightly increases in motion, it concludes with a sense of floating, as if smoke is gradually dissipating.
