When Reubke died in 1858 at the age of only 24 his achievements included two monumental works (a piano sonata and an organ sonata) and a few smaller compositions, including a Trio for organ. This Urtext edition brings together the two organ works in a new edition: the organ sonata is also known by the title of the 94th Psalm, whose words inspired its content. The Sonata, whose style and virtuosity show the influence of Liszt, is one of the greatest organ works of the whole Romantic period. The Trio, a musically charming but technically less demanding piece, should represent a welcome addition to the teaching repertoire for organ. The only original documents remaining for these works are the first editions. In this new edition we have attempted to correct obvious mistakes in the first impression and to offer cautious suggestions for improvements in dubious instances.
