Paganini is a famous violinist. He composed "Twenty-Four Caprices". Later Liszt selected five melodies from this collection, and also from Paganini's "Twenty-Four Caprices". He selected a melody from a violin concerto and used those six melodies as themes to compose six piano etudes in the form of variations, forming a collection of piano etudes. It is very difficult and is sometimes called "Liszt Paganini". "Grand Etude Collection" has been widely circulated and is still frequently played in high-level concerts.

p.s. Only the third of the six songs has a name, and the rest have no names. The first one is adapted from Paganini's "Twenty-Four Caprices", No. 5 and No. 6, and the second one is adapted from Paganini's "Twenty-Four Caprices", No. 17. The third piece is adapted from the finale of Paganini's Second Violin Concerto "Rondo imitating the sound of bells", the fourth piece is a transfer of No. 1 from "Twenty-Four Caprices", and the fifth piece is adapted from "Second Sonata". The ninth piece is adapted from "Fourteen Caprices", and the sixth piece is adapted from the twenty-fourth piece from "Twenty-Four Caprices". The majepa, hunting, etc. you mentioned are all in the piano super technique practice area of ??Liszt's twelve pieces, not in these six pieces. The third piece played by Lang Lang is the third movement of Prokofiev Op.83 (Op.83 is his seventh piano sonata).

If you still don’t understand anything, you can ask me.
