In Old Town Alexandria，Virginia，you can find Jamey Turner playing an unusual musical instrument，the glass harp（豎琴）.A glass harp is made up of different sized drinking glasses，each filled with water.
Turner makes music by running his fingers over the tops of the glasses.By doing so，each glass makes a different musical sound.Visitors to Alexandria like what they see and hear.They thank Turner by leaving a dollar or more in his box for donations.Jamey Turner is 78 years old.Turner became interested in playing the glass harp at the age of six，when he heard his father playing with a glass of water at the dinner table.He has been playing it for 50 years.
   Today Turner puts together his instrument by placing 60 different glasses on a wooden soundboard.He holds the glasses in place with rubber bands，which keeps them from breaking.He then adds different amounts of water to each one to create different musical notes.Adding or taking away just a little water will change the sound.Adding water to a glass will make a lower sound.The smaller bowls of water produce a higher sound，while the larger ones produce a lower ，deeper sound.
   Turner always uses low-priced glass because it sounds better than costly crystal（水晶） and he has more control over the sound.Before buying new glasses，he will test them in stores.He decides if they produce the right sound by rubbing his finger over the top of them.
   The glass harp was popular 300 years ago when composers like Wolfgang Mozart wrote music for the instrument.There have been about 400 pieces of music written just for the glass harp.But Turner plays all kinds of music，even popular music from China.Few people play the glass harp these days，but Turner says he sees videos of people experimenting with the instrument on YouTube.He hopes the next generation will continue making its music.
