It is possible to increase string tension by pulling the string across the fingerboard with the stopping fingers.  The pitch becomes slightly sharper and then falls to its normal pitch as the string is released.  Wider pitch variations are possible on lower strings.

Pitch bends by pulling the string. At first a string is pulled and released during vibration. Then, a string is pulled during vibration and released when vibration has finished. Finally, a string is pulled before excitation and released during vibration. The pitch bends are shown for the plucked, struck and bowed string and for bowed harmonics.


A ‘cracking’ sound can sometimes be heard as the string moves across the fingerboard.  This is the sound of the metal string against the fingerboard.
