Variation IX from Edward Elgar’s Enigma Variations (dedicated “To my friends pictured within”) is entitled “Nimrod” and is a tribute to A.J. Jaeger of Novello, Elgar’s publisher.
Michael Kennedy sums up the piece in his excellent book Portrait of Elgar:
Elgar admits that “something ardent and mercurial, in addition to the slow movement, would have been needed to portray the character and temperament of A.J. Jaeger.” Then follow these important words: “The variation is the record of a long summer evening talk, when my friend discoursed eloquently on the slow movements of Beethoven, and said that no one could approach Beethoven at his best in this field, a view with which I cordially concurred. It will be noticed that the opening bars are made to suggest the slow movement of the eighth sonata (Pathétique).”
Elgar had written to Jaeger and said he was “sick of music” and was “going to give it up”. Jaeger wrote a “screed” in reply, “all about my ingratitude for my great gifts,” and suggested he should visit Elgar for a talk. They went on a long walk and “he preached me a regular sermon, pointing out that Beethoven, faced with his worries, had written still more beautiful music – and that is what you must do”.
[Nimrod] has become a traditional requiem for commemorating the dead; to this use of it there has been some objection, but, in appropriate cases, what could be better than this intimate record of a real friendship?
