PROBLEM TO BE SOLVED: To automatically detect performance operation and instruct performance operation including fingering in the instruction for performing a keyboard instrument. SOLUTION: A MIDI(musical instrument digital interface) converter 301 generates a MIDI message and a MIDI data block based on the signal inputted from globes 100L, 100R, and a keyboard 200. Model performance data are stored in a model performance storage part 302, and a data comparing part 303 compares a MIDI converter 301 with a data inputted from a model performance storage part 302. An error information generation part 304 generates error information based on the comparison result, and based on the error information, a display part 305 displays that the performance of a user has contained an error. Moreover, a data storage section 306 stores generated performance data, and a sheet music generating part 307 generates a sheet music indicating the error information to print out the sheet music, based on the performance data stored in the data storage part 306.
