| 1. An electronic musical apparatus for training in timing correctly, said apparatus comprising:
a play timing notifying device which notifies reference time points in a music progression for operating said apparatus to
play music;
an operation detecting device for detecting each of player's operations on said apparatus subject to evaluation as a player
operates said apparatus with reference to said reference time points;
a time deviation detecting device for detecting a time deviation of each of said player's operations subject to evaluation
from corresponding one of said reference time points;
a tolerance range setting device for setting a tolerance range with respect to each of said reference time point by taking
into consideration a plurality of said detected time deviations, said tolerance range being for evaluating whether a detected
time deviation falls within said tolerance range or not; and
a tone generation control device which controls generation of tones for said player's operations differently according to
whether each detected time deviation falls within said tolerance range or not,
wherein said tolerance range setting device sets said tolerance range automatically based on said plurality of detected time
deviations.
