Provided is a musical instrument controller capable of accurately controlling a musical sound parameter. This musical instrument controller includes: a reception means for receiving, from a musical performance device, a sound emission start signal transmitted on the basis of a musical performance operation; a sensor for detecting an amount of displacement from a reference position; and a control means for generating a control signal on the basis of the amount of displacement from the reference position and transmitting the control signal to a sound generation device. The control means sets the reference position on the basis of the sound emission start signal received from the musical performance device.

A wearable pressure sensor coupled to a controller and transmitter/receiver that when activated sends a control signal.

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.
