This app tunes your instrument to a keynote of 432 Hertz (Hz). This is the frequency of the central A. 432 Hz, unlike the traditional 440 Hz, resonates with the electromagnetic frequencies around you. Want to know more about this theory? See (Dutch): https://drive.google.com/file/d/1Tzv4AeMssdYEoyRZovt5pE3N8X0VyR25/view?usp=sharing. NOTE: This is a DUTCH thesis, no translation available.
