If standing waves transfer no energy, how does a guitar string produce sound?

[dt19]

if a standing wave is a wave which transfers no energy, how is it that a guitar string produces a sound? because it produces it via a standing wave, and the sound is sound energy, so where does the energy come from?

A standing wave on a string carries no energy from one end of the string to the other.

It can, and does impart vibration on the air molecules around it, resulting in sound waves.
