There is provided an information processing device, an information processing method, and a program that can provide an information processing device, an information processing method, and a program that can effectively assist in learning performance. The information processing device includes a sensing data obtaining section configured to obtain sensing data regarding at least one of a motion pattern, a motion speed, a motion accuracy, and a motion amount of a motion element of a user in a practice in performance performed by movement of at least a part of a body of the user and a state of a result produced by the performance, an analyzing section configured to analyze the obtained sensing data and estimate information regarding the practice in the performance of the user on a basis of a result of the analysis, and an output section configured to output a result of the estimation to the user.

A musical instrument configured to generate a scratching sound effect includes a rotatable platform configured to support a record thereon, and a pedal (such as, for example, a foot pedal) operably coupled to the platform. The foot pedal is actuatable from a first position to a second position to rotate the platform, and in turn, the record.
