The Tarantelle in A-flat major, Op. 43 is a short piano piece in tarantella form, written by Frédéric Chopin in June 1841 and published in October 1841. It takes about 3 minutes to play. It is a moto perpetuo marked Presto, and requires an advanced technique. It was inspired by Gioachino Rossini's song La Danza, also written in the tarantella's characteristic 6/8 rhythm. Chopin went to some lengths to ensure the time signature was the same as Rossini's, and enlisted his friend Julian Fontana to check the best editions of Rossini's work for this detail. The manuscript shows Chopin changed his time signature from 12/8 to 6/8. There is no evidence the work was commissioned, nor was it dedicated to anyone.
