Please consider this as a perspective. God spoke (sang) the creation into existence. Call it theocymatics. http://www.5min.com/Video/Cymatics-How-to-Create-Patterns-with-Frequency-3177549
Now, the essential theological dynamic is psalmodic response, in which the spirit of the first is applied to another field in the right way, to show that we 'get it'. Psalm 1:1.
Call this ecclesiocymatics.
When will this new song be sung?
Before Christ returns, as he returns (The Great Day), after the Great Day?
Thus, a new perspective on millennial positions.
Love in God our Song,
