<p>The method involves generating a magnetic field by one or multiple electromagnetic pick-ups. The induction voltage or an induction current caused by the induction voltage caused by the change of the magnetic flux in the link is detected. The temporal run of the induction voltage or an induction current is evaluated. The frequency is evaluated as frequency of the link pulsatory in the magnetic field. Independent claims are also included for the following: (1) a device for determining the frequency of a string of a stringed instrument; and (2) a method for automatic tuning of a string of a stringed instrument.</p> |
