PURPOSE:To facilitate the confirmation of a memory information and the discrimination of a note information by utilizing an indication figure for a usual clock for indication of a scale for a melody. CONSTITUTION:A reference signal for time-counting is generated by an oscillator 11, the frequency of the signal is divided by a frequency divider 12 so as for the signal to be a signal for time-counting, a divided-frequency output is counted by a counter 14, and the content of the counting is indicated by an indicator 15a as a time. Moreover, the note information of the sound of melody is memorized in a memory 19 and the sound of melody is generated by a generator 13 in accordance with the content of the memory. And, the content of the memory of a melody memory 19 is renewed by a switch input control circuit 16 by a switch input, while the content of the memory of the memory 19 is read out by the switch input and encoded by a display control circuit 15, and thus the scale name or the note name of the scae is supplied to an indicator 15a for indication with shifting. |
