Rock and Roll Energy

All music is a study in physics; from the vibration in a singer's vocal cords, to the resonance of vibrating air in a violin, to the electrical signals from a computer that become a hip-hop beat. The electric guitar takes the cake, converting one type of energy into another, amplifying an electrical signal, and converting the energy back to sound.
