Musically Intelligible Sound (MIS), p. 2
Within the compass of lower piano notes, faithful acoustic rendering of pitch and timbre become significant issues. Each quality can be adversely affected, either by inharmonicity caused by higher order partials, or by piano design factors. Apart from tuning and voicing, best acoustic rendering may require a number of design modifications as well. Fuller discussion is provided in the link below, which includes a critical technical assessment of what I have done to achieve MIS in several remanufactured pianos that also incorporated the Fully Tempered Duplex Scale (FTDS).
