This visionary work for the virtuoso pianist, written in 1923, is now available for the first time. It is a prime example of Schnabel's mature style, written entirely without bar lines, but with copious performance instructions (English translations are given in the end matter of the publication). A link to the Schnabel Music Foundation's website is provided for those wishing to examine the 1923 fair copy of this remarkable five-movement work. For the college level or professional pianist.
