A tuner apparatuscauses a user to designate a musical instrument that is to be tuned and a reference pitch that is a standard upon tuning, by a process at a setting portion. A pitch detecting portiondetects a pitch of a performed note inputted via a microphoneand input portion. A target note specifying portiondefines a note name, which is positioned nearest to the performed note in a predetermined temperament (e.g., 12-note equal temperament), as a target note based upon the detected pitch of the performed note and the inputted reference pitch. Then, a calculating portioncalculates a difference between the pitch of the performed note and the pitch of the target note, and a display control portioncauses the display deviceto display the calculated difference. Further, the display control portionconverts the target note into a note name written in a score relating to the musical instrument to be tuned by using a transposition parameter relating to the musical instrument to be tuned that is stored in the storage portionand set by the setting portion, and causes the display deviceto display a staff in which a note corresponding to the note name written in a score is written.

Tuner apparatus for aiding a tuning of musical instrument

In an instrument performance learning apparatus, a storage section stores model performance waveform data representing a time series of individual performance sounds of a model performance. An input section inputs real performance waveform data representing a time series of individual performance sounds of a real performance. A pitch graph display control section detects each pitch of each individual performance sound from the stored model performance waveform data and from the inputted real performance waveform data, and displays a pitch graph representing transitions of the detected pitches. An amplitude envelope graph display control section detects each amplitude level of each individual performance sound from the model performance waveform data and from the real performance waveform data, and displays an amplitude envelope graph representing transitions of the detected amplitude levels, such that the amplitude envelope graph has a time axis common to that of the pitch graph while the amplitude envelope graph is located in an area of the display device which does not overlap with another area of the display device where the pitch graph is located.
