PURPOSE:To allow a practicer to recognize the classification of improper perfor mance operation. CONSTITUTION:When average values of misperformance of black and white keys are smaller than allowable values N1 and N2 respectively in a decision step SA11 (A=B=0), 'O.K. Tackle the next music.' is displayed (A display) in a step SA12. When the average value of misperformance of black keys is equal to or larger than the value N1 and that of white keys is smaller than the value N2 (A=1, B=0), 'Black keys are much misperformed. Once more.' is displayed (B display) in a step SA15. When the average value of misperformance of black keys is smaller than the value N1 and that of white keys is equal to or larger than the value N2 (A=0, B=1), 'White keys are much misperformed. Once more.' is displayed (C display) in a step SA18. When average values of misperformance of black and white keys are equal to or larger than the allowable value N2 (A=B=1), 'Keys are much misperformed as the whole. Return to the preceding music.' is displayed (D display) in a step SA21. |
