Playing on Samisen, Yokin and Kokin
Hand colored japanese albumen print around 1900.
The Shamisen (played by the left Geisha) is played with a plectrum. The Kokin (played by the right Geisha) looks very much like a shamisen but is played with a bow, which is tightened with the finger while playing. I could not find any information about the "Yokin" in the middle. It seems to be a simple version of a Koto.
