I made three tracks for Sophie’s birthday in November last year. This is one of them, and probably the most successful. It’s made by stretching the Confutatis Maledictis part from Mozart’s Requiem Mass, using Paul’s Extreme Sound Stretch (a great little tool, and free). Then the stretched part is choppped up and re-assembled in Reaper. Very simple, really, but quite pretty. The time-stretching exposes Mozart’s subtle layers of instrumentation that work behind the vocals.

Hello. I’ve updated the links. Not sure if the player works, but the file should be downloadable via the link. Your project is interesting – dauntingly long.
(not MY project, just one I thought you’d appreciate . . .)
I do appreciate – thank you.
