Sounds of enjoyment come from this carefully crafted viola shaped timepiece. The combination of the pendulum rocking at the top of the clock and the spinning pendulum at the bottom make this piece a true entertainer. The LED lights add to the rhythm of this clock as they are synchronized to each of the 18 melodies. Clock is battery quartz operated. Plays one of 18 melodies every hour on the hour from 3 different melody selections.
