<P>PROBLEM TO BE SOLVED: To enable even a player who can not read a musical score to practice step by step by keying indications using a musical score by optionally switching display styles of the keying indications. <P>SOLUTION: Keying indication display parts 6 to 8 display musical performance indications in mutually different modes. Those modes are a mode in which keying timing is displayed on a musical score, a mode in which marks indicating musical sound lengths are displayed while being made to correspond a keyboard figure, and a superimposition mode in which those modes are displayed one over the other. A switching part 5 can be operated either at the start of a musical performance or in the middle of the musical performance. Musical performance data are read out to the keying indication display parts 6 to 8 when the start of a lesson is indicated or when correct keying is done. <P>COPYRIGHT: (C)2004,JPO |
