Abstract: An information processing system includes an image obtaining circuit and a display control circuit. The image obtaining circuit is configured to obtain observation images of a first keyboard of a first keyboard instrument. The display control circuit is configured to display, on a display device, the observation images and reference images. The reference images include moving images of at least one hand and one or more fingers of a reference performer who is playing a second keyboard of a second keyboard instrument. The at least one hand and the one or more fingers of the reference performer are displayed overlapping the first keyboard included in the observation images.
