FIGURE 16–8 Transient response of a plucked string. Higher harmonics decay more rapidly than the fundamental. (Rate of decay of higher modes is exaggerated.)

16.8 Bowing

By drawing a horsehair bow across a string, the string will vibrate, producing a sustained or continuous tone. The horsehair is normally coated with rosin, a wood sap product, which increases the friction between the bow and the string. As the bow is drawn across the string, the string is first pulled laterally in the direction of the bow motion. Then the string slips back and stops, allowing the bow once again to engage and pull the string laterally. This alternate pull and slip is forced by the fundamental vibration of the string to synchronize with the period of vibration.3’ 4’ 5 See Figure 16–9.
