Fork Frequency: 440Hz Your A4: 440.2Hz Difference: Sharp by 0.2Hz (0.8 cents) Mark: 100% Great Job! To get 100%, you need to be within 0.9 cents of 440Hz. There is a slow beat at A5 when playing A4Fork, but we are not trying to tune a good A4Fork, we are trying to match the fundamental partial of A4 with that of the fork. (Good unison practice dictates that we should make a compromise between the beating at A4 and the beating at A5, if we were trying to tune a good A4Fork unison.) By the way, there are only nine preset recordings. I.e. you can't get better than this mark. Thanks for playing. [cjtoolbox name='Try Again']
