Music
Music gives us a way to express feelings when we have no words; a way to understand things with our hearts when we cannot with our minds. Music allows us to move around those big invisible pieces of ourselves and rearrange our insides so that we can express what we feel even when we can't talk about it. 

Using the vibrations of music, we can alter our vibrational energy through sympathetic resonance, or entrainment.

The Harp
Pythagoras said "Music Heals" and he used the lyre as a healing instrument, developing theories about the effect of pitch and mode on the human body.

The ancient world revered the harp as a gift from the Gods and used it as a celestial communications device. Listening or playing the harp could connect heaven and earth and deliver messages from the angelic realms.
