This quote was actually crafted by University College Dublin student Shane Fitzgerald. Shortly after Jarre's death, Fitzgerald uploaded https://en.wikipedia.org/w/index.php?title=Maurice_Jarre&type=revision&diff=280558491&oldid=280527998 the false quote to Wikipedia to test "how our globalised, increasingly internet-dependent media was upholding accuracy and accountability in an age of instant news," according to the Associated Press. "The sociology major's made-up quote…flew straight on to dozens of US blogs and newspaper websites in Britain, Australia and India. They used the fabricated material, Fitzgerald said, even though administrators at the free online encyclopedia quickly caught the quote's lack of attribution and removed it, but not quickly enough to keep some journalists from cutting and pasting it first. A full month went by and nobody noticed the editorial fraud. So Fitzgerald told several media outlets in an email and the corrections began." The Guardian and The Herald "are among the only publications to make a public mea culpa," the Associated Press continues.

The silence of the dead;
I care not, so my spirit last
Long after life has fled.”

Peter Quince at the Clavier (1915)
Context: Just as my fingers on these keys Make music, so the self-same sounds On my spirit make a music, too. Music is feeling, then, not sound;
And thus it is that what I feel,
Here in this room, desiring you,
Thinking of your blue-shadowed silk,
Is music.

“Life is for the living.
Death is for the dead.
Let life be like music.
And death a note unsaid.”
