Generally, changing the pitch of a recording without changing the 
tempo can introduce a lot of distortion. This is also true of 
changing the tempo without changing the pitch. Changing the pitch and 
tempo the same amount usually doesn't introduce audible distortion. I 
wouldn't expect this to be any different just because the amount of 
change increases (or decreases) gradually over the course of the recording.
