Pomp and Circumstance Marches central "Trio" section. March No. 4 was completed on 7 June 1907, and dedicated "To my friend Dr. G. Robertson Sinclair, Hereford". It was first performed on 24 August 1907, in the Queen's Hall, London, conducted by the composer. The instrumentation is: piccolo (with 3rd flute), 2 flutes, 2 oboes, cor anglais, 2 clarinets in B, bass clarinet in B, 2 bassoons, contrabassoon, 4 horns in F, 3 trumpets in A, 3 trombones, tuba, timpani (3), percussion (side drum, bass drum & cymbals), 2 harps, and strings. The "Trio" was used by Elgar in a song called "The King's Way"
Pomp and Circumstance Marches they are directed to play the passage ""sul G"" on the same string, for the sake of the tone-colour, and the accompaniment is from the harps, low strings and bassoons. The grand tune is repeated, as we expect, by the full orchestra; the opening march section returns; the grand tune is repeated once more, in the "home" key of G major; and the last word is had by a re-statement of the opening rhythmic patterns. The march prepares the audience for its end as surely as a train pulling into a station, with the violins, violas, and cellos ending on
