On the Singing of Creation Into Being
“And [Eru Ilúvatar] spoke to [the Ainur], propounding to them themes of music; and they sang before him, and he was glad….Then Ilúvatar said to them: ‘Of the theme that I have declared to you, I will now that ye make in harmony together a Great Music…
“Then the voices of the Ainur, like unto harps and lutes, and pipes and trumpets, and viols and organs, and like unto countless choirs singing with words, began to fashion the theme of Ilúvatar to a great music; and a sound arose of endless interchanging melodies woven in harmony that passed beyond hearing into the depths and into the heights, and the places of the dwelling of Ilúvatar were filled to overflowing, and the music and the echo of the music went out into the Void, and it was not void.”
–The Silmarillion, page 3.
“Where were you when I laid the foundation of the earth?
Tell me, if you have understanding.
Who determined its measurements—surely you know!
Or who stretched the line upon it?
On what were its bases sunk,
or who laid its cornerstone,
when the morning stars sang together
and all the sons of God shouted for joy?”
