Pianoscope tuning Kawai and Yamaha (440 Hz) tone comparison

The pianoscope’s tuning algorithm searches for an individual, preferably optimal solution for an instrument. However, even the preferred intervals are never completely pure, but always slightly tempered. This is due to the nature of the equal temperament and the inharmonicity of the piano. The preferred intervals, however, are much purer than the non-preferred ones.

Some ears are more acutely attuned than others and can pick out these ordinarily “inaudible sounds,” just as some eyes can see colors that are invisible to other eyes. Which brings us to a realization of what a wonderful apparatus the human ear is, and the interesting process through which sound vibrations go in being taken into our consciousness, bringing their story of human emotions, or jarring dissonances and of exquisite harmonies!
