Abstract: A tuner apparatus 10 causes 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 110. A pitch detecting portion 130 detects a pitch of a performed note inputted via a microphone 20 and input portion 120. A target note specifying portion 140 defines 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 portion 150 calculates a difference between the pitch of the performed note and the pitch of the target note, and a display control portion 160 causes the display device 30 to display the calculated difference.

Abstract: 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.
