Innocence is No. 5 of Friedrich Burgmüller's 25 Études faciles et progressives, Op. 100, published in Paris in 1851. Burgmüller, born in Regensburg, had moved to Paris around 1832, where he taught and wrote salon music and pieces for his pupils.
Like the rest of the book, it is a study disguised as a character piece: here the goal is light, even semiquavers in three-four time, with the hand turning smoothly at the bottom of each run.
