Prokofiev's pianistic output of this period is scarce since he put all his efforts into composing his opera The Love for Three Oranges.
Both were written in order to mitigate his economic situation because of the delay of the opera's premiere;[4] however, he did not obtain the money in royalties he expected for them.
