Provided is a musical instrument tuner which is easy to use, and which enables stable and accurate tuning. This musical instrument tuner comprises: a sensor device which can be attached to a musical instrument; and an operation device which is capable of wireless communication with the sensor device. The sensor device comprises: an acceleration sensor having at least two detection axes; a frequency detection means which detects, as the detected frequency, the frequency of vibration of the musical instrument generated by the operation of the musical instrument, on the basis of output of the acceleration sensor; and a sensor-side communication means which transmits, to the operation device, transmission information which includes information concerning the detection frequency. The control device comprises: a control-side communication means which receives transmission information transmitted from the sensor device; a display means; and a control means which generates tuning information for the musical instrument on the basis of transmission information received from the sensor device and displays this tuning information on the display means.
