Gerald Reynolds writes: "This edition marks the first publication of the R�ntgen's Sonata in C-sharp Minor (1928). I was first introduced to the work while visiting the composer's grandson Jurriaan R�ntgen in Amsterdam during the summer of 2015, at which time Mr. R�ntgen generously gave me a recording of the work. I was immediately taken with the piece and resolved to find the score, record and edit it with the hope of bringing it to the wider attention of pianists and piano aficionados with a new publication of it, through my relationship with Nimbus Publishing, UK. Previously, the Sonata in C-sharp minor (1928) existed in manuscript form in three versions designated as A, B (catalogue # 107/062B also with the date 14 Dec '28 in pencil on the title page) and C (catalogue # 107/062C - no date). All originals are located in the R�ntgen archives at the Nederlands Muziek Instituut, Den Haag, The Netherlands."
