This thematic catalogue offers a concise, systematic overview of Erno Dohnanyi's oeuvre, with numerous music examples to facilitate identification and other pertinent, up-to-date information about each composition. For decades the music of Hungarian composer-pianist Erno Dohnanyi (1877-1960) has remained in relative obscurity - except for a few popular works - due to a series of unfortunate circumstances. He was the victim of malicious slander after he fled war-torn Hungary in 1944; the tragic result was that his music was silenced for decades in his home country. He was also branded a conservative by those who sought to dismiss traditional musical language and forms in search of 'modernism'. As a consequence of Dohnanyi's long and enormously successful international career as a performer and pedagogue, his legacy has been scattered throughout Europe and the United States. Today, having been reassessed from the perspective of several decades, and as a result of new research initiatives and an increased access to archival and commercial recordings, Dohnanyi's music is enjoying a long-deserved revival. The fact remains, however, that much of it remains unpublished, including several of his numbered works. In addition, a large number of published works are now out of print and difficult to find. Many of the publishers of his music have gone out of business or have changed hands. Because of this dearth of published music and reliable information, this thematic catalogue will fill in that regrettable lacuna by providing incipits and as much up-to-date information as possible about the composer's 48 opus-numbered works, his juvenile and mature works without opus number, transcriptions, cadenzas, arrangements of other works, and pedagogical studies.
