Claim 2:
3. A mode switching method for performing, in a transmitter for musical instrument which transmits a sound signal emitted from a musical instrument to an outside using a battery arranged inside a main body of the transmitter, switching from a first mode to a second mode in which power consumption of the battery is smaller than the first mode, the mode switching method comprising:
a detection step for detecting an acceleration of the main body in the first mode, and
a switching step for transitioning to the second mode when the detection value detected by the detection step shows a value within a predetermined range during a predetermined time;
wherein the mode switching method further comprises:
releasing the second mode to transition to the first mode when the detection value of the acceleration detected in the detection step exceeds a release threshold value in the second mode; and
a release threshold value setting step for setting the release threshold value based on the detection value of the acceleration detected in the detection step at a time of transition from the first mode to the second mode;

wherein the detection step detecting three axis accelerations of the main body, and
the release threshold value setting step setting the release threshold value based on a second greatest detection value and a third greatest detection value among detection values of the three axis accelerations.
