Instead of trying to mount a laptop onto a music stand. here's what I did.
Purchased a touch screen monitor (15.6 inches) and hooked it up to my laptop as a second display.
Mount the monitor on the music stand.  
Open MSpro  and extend(move) it's display over to the touch screen monitor.
MSpro runs on the external monitor and I can then use the laptop screen for whatever other app I need at the same time..

You can buy a 13.5 touch screen if you want smaller.  I recommend the 15.6 though. It's larger than most tablets

The monitor weighs much much less then a laptop and it is very thin.   The monitor I have is mounted on the  built in music rest on my keyboard.            
Hope this helps.

Which brand of touch screen monitor (15.6 inches) are you using?
Thanks,
