The music room which is located at the end of the 17th-century wing of the villa, is a long rectangular room used for small private concerts, and probably reserved only for women since this part of the villa was mainly used by them. The walls are empty today but bear the mark of paintings and their frames that were once hung here.
The peculiarity of the hall consists in the ceiling decorations, once again the most interesting part of the master suites. Just above the doors and windows runs a band painted with false niches where female busts of distinguished women of ancient Rome were placed. The monochrome busts rest on small, marble, painted shelves where their names are recorded; the famous women of this gallery seem to talk to each other, as portrayed in the various poses and movements. The creator of this decoration, still unknown, has come up with a carefully thought out perspective play, as each bust is seen in the right perspective within the room. The risk, otherwise, would be to see these faces flattened and dramatically deformed. Beyond the niches with pointed arches, where the shadows cast by the painted busts seem to lengthen, a frame opens up to support two stained glass windows, one for each short side of the room. Higher up is a compartment divided into three bays with the central one shaped like a sail. It is an interesting play of perspectives since it is able to greatly increase the height of the room and its spaces. One of the windows was painted open and protruding into the room, to contribute to this sense of perspective illusion.
