Before the exam is given, the piano must be untuned by a standard amount as specified by the
PTG Examination Manual. This is taken care of by page UnTune, which uses the supertuning
page SUP to generate an untuned setting equal to the setting from page SUP plus or minus four
times the tuning tolerance for that particular note. Flat and sharp deviations alternate. For
example, the tolerance for C3 is one cent so C3 is tuned four cents sharp with respect to the
supertuning, C#3 is tuned four cents flat, D# four cents sharp, etc. Where the tolerance is six
cents, the notes are tuned alternately twenty-four cents flat and sharp.
