The Japanese instrument koto is very unique and makes a beautiful sound. It looks kind of like a harp, but instead of being upright it is placed on the ground. Since the koto is placed on the ground, with the strings facing up of course, the koto player's sit on the floor directly behind the instrument.
The koto can be played at any tempo. Normally faster-paced songs are played on the koto faster, with more strings being played at one time. If the song is slower, the koto is normally played slower, using less strings at a time.
If you like classical music, with a bit of a flair, you will probably like the koto played by an experienced musician.
