Beats of a String of Piano (1st Report)
Takesi Yanagisawa, Kijuro Nakamura · Journal of the Japan Society of Precision Engineering · 1967
Up to the present, it is believed that beats of one string of piano are false beats (defined by W.B.White) caused by inharmonicity. This paper discusses particularly the relationship between false beats and inharmonicity for a certain piano.It is shown from the experimental results that the beats of one string of a piano consist of false and true beats. The ratio of false to true beats is small, and it is 2/11 in this experiments. The false beats of a string do not exist in the soprano part, and the beats in the soprano part are the true beats. Deformation of a support of string decreases the false beat-rate.
