Play the Koto in GarageBand for iPhone
The koto is a traditional Japanese zither-like instrument with 13 strings mounted over bridges on a long hollow resonant body. The strings are tuned to a minor pentatonic scale called Hira Choshi. The koto is played by picking or plucking the strings with the right hand, and pushing or pulling the strings with the left hand to change the pitch and create vibrato.
