<p>Disclosed is a tuning module for a stringed instrument. The tuning module comprises a manipulating section, a sound detecting section, a waveform shaping section, a tuned status display section, a memory section, a control section and a housing. The control section determines upon input of a power-on signal a reference frequency in response to reference frequency hold/reset signals and a frequency of a current sound in response to a frequency detection signal. The control section outputs a tuning completion signal to the tuned status display section when a difference between a corresponding sound frequency of the reference frequencies and the frequency of the current sound is in a predetermined error range, and outputs a deviation display signal to the tuned status display section when the difference goes beyond the predetermined error range.</p> |
