This video describes how to perform a pitch raise with the PianoMeter piano tuning app. After entering some basic information about the piano, you take some pre-measurements of select sample notes to calculate an appropriate overpull curve. The piano is tuned starting at the tenor break, first upward through the treble, then downward through the bass. The pitch raise is a quick "rough tuning" pass that should be followed by a slow fine tuning.
