Abstract
In a tuner that measures a frequency of a tone of a musical instrument to be tuned, and displays a pitch name of the tone of the musical instrument and a difference of pitch of the pitch name from the standard pitch, thereby to tune the musical instrument, even during a time duration of measuring a frequency of the tone of the musical instrument, sampling of an electric signal corresponding to the tone of the musical instrument is carried out in succession, and a number of sample data that is required to measure the frequency are always stored in a memory of a data storage part. When the computation process for measurement of the frequency is completed, the next computation process for measurement of the frequency is started at once so that the contents of displays of a pitch name and a difference of pitch can be updated substantially at intervals of the period of a time duration of performing the computation process for measurement of the frequency.
