Casimir Ney is most famous for his book of 24 preludes for solo viola, which are extremely difficult to play. He also wrote a trio, a quartet and a string quintet, as well as
Eighteen Caprices for Violin on the G-string, and a few works for viola and piano. He also wrote many transcriptions. The
24 Préludes for viola, published in Paris around 1849, are without a doubt the most ambitious attempt in the 19th century to demonstrate the technical possibilities of the viola. The preludes are designed around the 24 keys, are not really preludes in the traditional sense. They are not introductions to anything else. The choice of terminology, "prelude" is used to convey a sense of liberty. Unlike etudes, these pieces are meant to be more than just tools for study. The preludes are not arranged in order of difficulty and do not necessarily each focus on a specific technical point. The technical demands made on the player are in some places unbelievable. For example, the interval of the 12th in the
Prélude No. 7 is just short of half the string length and is impossible to play except on a small viola with very big hands. Some of the other difficult techniques asked of the performer are many
double stops, double
harmonics, left hand
pizzicato, 4 finger pizzicato, and the exploration of the full functional range of the instrument. ;Original compositions •
