Ethel Smyth’s first orchestral work, the Serenade in D Major for Orchestra, was composed in 1889 (and possibly early 1890) and was premiered at a Crystal Palace concert on 26 April 1890. The work was received well by the audience and garnered positive notices in the press. This critical edition is based on a photocopy of the autograph manuscript, now in the Royal College of Music Library, with reference also to a fair copy of the score, now in the British Library. The extensive critical notes document the changes made by the composer, as well as editorial and performance suggestions made by both the composer and August Manns, who conducted the premiere performance.
