The song is titled "The Paino" because that's partially what it is about. Look at the first verse. The "her" in the first line is referring to a piano, and each of the following lines in this verse fits with this idea (the "hammer" being a straightforward part of the instrument, "teeth" being the keys, "tongues" the strings, and "skeleton" the frame).
It is appropriate that the first line, when taken out of context, has a violent quality to it, because this song also seems to be about dealing with problems around oneself (in this example, intolerable familial relationships) and venting the aggression this causes (pounding on the piano's keys or "teeth.")
However, it would appear that the piano is an object with which the speaker associates an absent person ("Where I feel your fingers have been") who was formerly another means of solace from the violence around her (in PJ's case, we'll assume this person is her grandmother). Still, the speaker continues to play the piano and escape her unstable family life, the memory of the absent person giving her the will to do so ("Ghostly fingers/Moving my limbs").
