Patent ID: 7323631

Claim:
An instrument performance learning apparatus having a display device for displaying a progression of a real performance to enable visual comparison of the real performance with a model performance, the instrument performance learning apparatus comprising: a storage section that stores model performance waveform data representing a time series of individual performance sounds of the model performance; an input section that inputs real performance waveform data representing a time series of individual performance sounds of the real performance; a first graph display control section that detects each pitch of each individual performance sound from the stored model performance waveform data and each pitch of each individual performance sound from the inputted real performance waveform data, and that displays a first graph presenting transitions of the pitches detected from both of the real performance waveform data and the model performance waveform data on the display device; and a second graph display control section that detects each characteristic value representing a characteristic of each individual performance sound of the model performance from the model performance waveform data and each characteristic value representing a characteristic of each individual performance sound of the real performance from the real performance waveform data, and that displays a second graph representing transitions of the characteristic values detected from both of the model performance waveform data and the real performance waveform data on the display device, such that the second graph has a time axis common to that of the first graph while the second graph is located in an area of the display device which does not overlap with another area of the display device where the first graph is located.
