The concerto is quite traditional, both in terms of its fast-slow-fast structure and in terms of the composer's personal aesthetic; the style is instantly recognizable as Martinu's: broad, wistful melodies soar over percolating rhythms with the orchestral piano providing particular color.

The score reveals the influence of Igor Stravinsky, including a quotation of a motif from Petrushka in the second movement. The score contains a prominent part for an orchestral piano. It takes about 17 minutes to play.
