The aim of this dissertation is to help assimilate the solo piano works of Robert Muczynski into the active 20th century piano repertoire, by providing pianists, musicologists, and listeners with the composer’s complete solo piano output on CD, for the first time. Of the fifteen compositions contained therein, only eight can be found on commercial CDs, with another two available on out-of-print LPs, and the last five never recorded on any recording medium. This circumstance diminishes Muczynski's piano music - the largest part of his catalogue - to a footnote in the American chapter of this instrument’s history. The ultimate goal is to have these recordings commercially released as a two-disk set. This release will follow an earlier disk of Muczynski's chamber music with piano, recorded for Brilliant Classics and released in the spring of 2017.
