Abstract
The physical spectrum of the sound of a bell contains a great number of
harmonically unrelated eigenfrequencies (partials). Despite this inharmonicity,
one can usually perceive a dear pitch when a bell is struck. In a mistuned bell
this strike-note pitch often does not coincide with any frequency present in the
spectrum of the sound. This paper describes how the subjective pitch of the
strike note is meagured as a function of systematic frequency shift in selected
partials. A digital filt ering technique is used to manipulate the sound of a real
bell. The octave, the twelfth and the upper octave partials turn out to be the
major contributors to the strike-note pitch.
