If your floor is hardwood you can do one or both of the following:
1. Put small felt pads on each corner (felt is used in pianos for dampening you know)
2. Cut four small squares out of a sheet of cork (office depot etc) and place them under each corner. (cork is mostly air and is used to sound proof rooms.
Carpeting your whole room is absolutely not necessary. Granite and other rocks do not absorb or defract sound or vibrations.
