I've heard a phrase Producers use in Recording, about having a Song Recorded where the execution of the Chorus is 'perfect' in one giving, but flawed in another, and they 'Fly the Chorus', meaning copy the section of the Recording with the good one and paste it in for other givings of the Chorus. Some technological 'splicing'.
It could be the second or the third and 'Fly' it back to replace the flawed first giving.
Or any way it goes, just to get three good givings of the Chorus.
I suspect singers flub a bit of Prosody, not hitting the beat exactly right each time, and Producers 'have the ears' to hear that flaw, and know how to fix it without requiring another Recording Session with live singers/players.


There will always be another song to be written. Someone will write it. Why not you? www.garyeandrews.com
