When I put my 97 Buick LeSabre in reverse it makes a sound, like a harmonica (hmmmm) would if you were trying to get it on pitch. It is brief and only happens once and awhile Please advise.
Interesting. Noises come from so many different places. I am going to suggest you isolate the "brief, once in a while sound" to where you hear it coming from, AND when you hear it. Once you do that, you can duplicate the sound and have your technician check it out.

This is a new one for me. I would first recommend that you check your transmission fluid level. Do this when the vehicle is warmed up and running, in neutral and on level ground. If the level is ok, I suggest bringing your vehicle to a qualified technician that can listen to the sound first hand. If you are having trouble finding a trustworthy technician, check out the list of female friendly shops on Ask Patty.
