A girl demonstrates playing an acoustic guitar using her hands to create percussion noise on the body of the guitar.   A girl enters a room where an acoustic guitar is leaning against a sofa and sits down on the sofa and begins to play the guitar.   The girl uses her right hand to make beats with the guitar and picks chords with the left hand while staring intently at the guitar.   The girl continues to play intensely, occasionally nodding her head to the rhythm.
