Details: The largest part of the output of the Hamburg-born composer and writer Walter Niemann (1876-1973), a student of both Humperdinck and Reinecke, is piano music: an astonishing 1,000 or so pieces, divided into 189 opus numbers. Most of them are lyrical miniatures in a warm and approachable late-Romantic style, some evoking the music of the past. Occasionally, though, as in Hamburg, a recollection of scenes from his childhood, a degree of mild dissonance indicates his desire to stay true to his memories of growing up in a port city.
