외젠 이자이 (Variations on Paganini's 'Caprice no. 24', for solo violin)

Caprice No. 24 in A minor is the final caprice of Niccolò Paganini's 24 Caprices, and a famous work for solo violin. The caprice, in the key of A minor, consists of a theme, 11 variations, and a finale. His 24 Caprices were probably composed between 1802 and 1817, while he was in the service of the Baciocchi court. It is widely considered one of the most difficult pieces ever written for the solo violin. It requires many highly advanced techniques such as parallel octaves and rapid shifting covering many intervals, extremely fast scales and arpeggios including minor scales, left hand pizzicato, high positions, and quick string crossings. Additionally, there are many double stops, including thirds and tenths.
