I notice that good electric guitarists can make their instrument "whine". What is this technique called and how is it done?

An example of the technique is found in the piano exit from "Layla".

  • This tecnique is eased by using a guitar with a higher action than usual.

  • I'd like to extend the comment from @Tim - a little more tension and a little extra height is desired, so something akin to a rhythm guitar setup. Like 10s not 9s. It is common to play normally on your "slide" instrument; a little harder to bend notes, but you don't, because you have a slide for that. You don't need to go full dobro. Dec 13, 2020 at 15:20

The "Layla" outro features guitarist Duane Allman using a slide.

Here's how Wikipedia describes slide guitar:

It involves playing a guitar while holding a hard object (a slide) against the strings, creating the opportunity for glissando effects and deep vibratos which reflect characteristics of the human singing voice.

Allman was known to wear a small glass medicine bottle on his finger to produce this effect, but it was a very common technique among guitarists. The slides can be made from glass, metal, clay, and other materials (I have seen guitarists use a plastic lighter as a slide in a pinch).
