Music for the Royal Fireworks
He was a major contributor to the "New Oxford History of Music" and the fifth edition of the "Grove Dictionary of Music and Musicians", as well as English editor to "Die Musik in Geschichte und Gegenwart", for which he wrote many of the entries on English composers. In 1953 he was a member of the editorial board for the "Hallischen Händel-Ausgabe". He produced critical editions of Handel's Concerti Grossi, Op. 6, "Water Music" and "Music for the Royal Fireworks" (1962–1966), the first chance for English audiences to hear the works in their original scoring, rather than in the suites heavily orchestrated by Hamilton Harty. He also acted as the general editor of the Eulenburg miniature scores series.
