String bending is executed by fretting a note on the guitar
Factors influencing string bending
There are numerous mechanical and acoustic properties which heavily influence the resultant pitch from a string bend. Analysis of the physics of string bending [3] suggests that the resultant pitch of a string bent at its midpoint is given by
where L is the length of the vibrating element, T is the tension of the string prior to bending, is the bend angle, E is the
Thus, the pitch is not only dependent on the bend angle, but on material properties of the string such as Young's modulus; this may be interpreted as a measure of the stiffness of the string. The force required to bend a string at its midpoint to a given angle is given by
It is important to note that the resultant pitch from string bending is not linearly correlated with the bending angle, and so a player's experience and intuition is important for accurate pitch modulation.
