But that would change the tempo. If you have a full-function DAT tape
drive or digitally record it on a magnetic device, you can re-sample or
change the read rate, enabling you to change the pitch or the tempo
individually (changing the tempo is done all the time on TV for movies
- look for "This movie has been time-compressed" on the lead-in). This
trick is also used often when re-recording pieces of music to replace
sections previously recorded (the splices are done during pauses in the
music, and can be rendered totally silent when using digital equipment).

I have done this for fun - recording your voice & changing the tempo
makes you a faster speaker then that "Federal Express" guy, and I can
guess what my 7 year old boy will sound like when he's 18 ;^)

Now the analogy become raising and lowering both the bridge and river
in and out of phase.
