Training type electronic musical instrument with keyboard indicators

A keyboard type electronic musical instrument, comprising:

• keyboard means including a plurality of keys with respective allotted musical notes and display elements each provided for a different one of said keys;
• memory means for storing note data and duration data forming a musical piece in accordance with a progression of the musical piece;
• musical tone signal generating means for generating a musical note signal of a tone determined by an operated key of said keyboard means;
• indicating means connected to receive the note data and duration data from said memory means for lighting, in response to the note data, a corresponding display element in said keyboard means to indicate a key to be operated;
• comparing means for comparing the note data successively read out from said memory means and key code signals generated by said keyboard means and representing notes of keys successively operated;
• counting means coupled to said comparing means for counting instances of noncoincidence between a key specified by the note data and a key operated on said keyboard means;
• detecting means for detecing a deviation between a normal key operation timing defined by the duration data from said memory means and an actual timing of key operation on said keyboard means;
• accumulating means for accumulating the deviation detected by said detecting means with respect to each key operation;
• and
• display means for displaying a selected one of a result of comparison between the note data and the operated key, and an accumulated deviation of key operation timing.

• accumulating means for accumulating the deviation detected by said detecting means for each key operation;
• subtracting means for subtracting, when a key operation timing deviation is smaller than a predetermined value after a predetermined number of data read out from said memory means is exceeded, a value proportionate to the accumulation of the key timing deviation from the deviation accumulated by paid accumulating means, and
• display means for displaying a selected one of the counted instances of noncoincidence between the operated key and the note data, and the accumulation value of the deviation of key operation timing.
