is it the suite fracaise for piano or is there another suite for solo piano that is just titled as you posted? apologies i am pretty familiar with poulenc but his piano output was really sizable. so i am not super privy to all of it...yet
i just acquired an oversized vintage durand edition score of this about a month ago, i will dig it up and check. have you listend to recordings, do different perfomers (preferrably separated pretty well chronologically) play it similarly as you score?
what edition (and year of publication) are you working out of? mine is a first edition i believe, i have not seen any revisions. will get back to you. i'll try and post a picture of it.
