                                                          There are two answers to this question: Many see all keyboard instruments as a family of instruments unto themselves, and in this case the piano belongs with harpsichords, clavinovas, accordions, etc.  However, others say the piano is technically a percussion instrument since the keys actually govern hammers that strike or hit internal metal strings.
