Duane When you're an aural tuner, you learn to recognize 5 - 10 cent intervals. But remember, this is just for pitch raising, where dead on accuracy is not critical. Once the piano is at pitch, the real tuning takes place.

When I've finished my 2-octave temperament, the sharpness has slipped to about 40% with full strip muting. Octave 5 is usually flatter than the rest of the piano, so I listen for that before beginning; if it is, then after I do the temperament, I go up to the top, stretching 5-10 cents more in that octave, then tuning fair octaves the rest of the way up.Then I tune the bass from the temperament down, knowing that the temperament has gone down to maybe 35% sharp. Then I tune unisons. About 90% of the time, this puts the piano within a 5-cent window of the correct pitch for every note. You get to recognize the brands of piano that need more of less sharpness to start.
