## What is Temperament Toolkit?

Contains reference pitch files for A220, A440, and C523.3, as well as the contiguous major 3rd (M3) interval beat rate tones for the F to F temperament. 

Selecting the option to 'Ignore silent mode" allows the watch to playback the tones without having to turn off silent mode. If silent mode is turned on and this selection is not toggled, no audio will play back.
