La campanella is a set of pieces derived of the same Paganini Violin Concerto No.2 in B Minor, the most popular is the S.139 versions in 1851, tho thats not the only piece derived from that concerto, there exists the "Grande Fantisie de bravoure sur La Clochette", the "La Campanella S.140 (1834)" and the more popular "La Campanella S.139 (1851)" the more recent la campanella's are the most simplified version of La Clochette, considered being the most difficult Liszt piece (technically wise) the recent versions are still technically dificult, but like, La clochette is the hardest, just look it up, you will die.
