Instrument: Harmonia

Her hobby is playing along to her favorite songs on her MP3 player.
Ranging from hobbiests to professionals, every day a motley mix of people who love to play music appear around the lake that the park wraps itself around. The sound is entrancing and ever-changing. The music reverberates and carries across the  surface of the water, mingles among the lush greenery, and is carried away again on the wind. There is no need to speak about it, each perhaps discovering this unique accoustic atmosphere on their own, the notes communicate for them. The water becomes the stage for a spontaneous orchestra.
These are just a few that I ran into, so go see more for yourself!^-^
