Harriet Cohen’s influence on Sir Arnold Bax’s music was arguably greatest on his piano music for which she was his muse and frequent dedicatee as well as constant performer. It is therefore surprising that she recorded so little of it commercially aside from the Viola Sonata with William Primrose and a handful of piano miniatures. There also exists a live recording of Winter Legends from a BBC broadcast but sadly none of her performances of the piano sonatas were captured either on vinyl or tape. While many have claimed she was a pianist of limited ability (superb in Bach but compromised in pieces requiring a more formidable technique), she still possessed an understanding of Bax’s music that she acquired from having known the composer on very intimate terms for much of their lives. She also imposed an unofficial ban on others performing his piano music, which of course prevented it from being played and recorded by pianists who might have been better able to promote it during Bax’s lifetime. As a result, we have very few recordings of Bax’s piano music recorded during the composer’s life but we are lucky to again be able to hear one set of the sonatas and selected piano pieces played by a friends and contemporary of the composer who understood his intentions and whose playing of these major works deserves to be described as authoritative.
