7. 2、Therapeutical Music Analysis from the view of Traditional Chinese Culture

8. Traditional Chinese Culture
Chinese ancestor, FuXi made music instrument, Se and Xun to treat diseases. Ancient long-liver, PengZu cultivated his moral character, including practice music, to get longevity. Ancient emperors, SanHuang and WuDi made music temperament to make his people more healthy. Ancient emperors, DaYu produced Yubu song to make people apart from the disease.

26. Overall Analysis (2.Spectra)
Strong Bass: Spectra Level in the band under 1000Hz has 20dB higher than in the band over 2000Hz . Body Vibration: High and stable spectra level in the band from 50 to 200Hz, it’s suitable to be applied in Body Vibration Therapy. Rich Overtone： 16 overtones in the band under 1000Hz. And there are temporally stable Pitch in background music.
