text: When a string is bowed or tone in a wind instrument initiated by vibrating reed or lips, a phenomenon called mode-locking counteracts the natural inharmonicity of the string or air column and causes the overtones to lock precisely onto integer multiples of the fundamental pitch, even though these are slightly different from the natural resonance points of the instrument.
text: However, this inharmonicity disappears when the strings are bowed, because the bow's stick-slip action is periodic, driving all of the resonances of the string at exactly harmonic ratios even if it has to drive them slightly off their natural frequency.
