Twang is an onomatopoeia originally used to describe the sound of a vibrating bow string after the arrow is released.
[1] By extension, it applies to the similar vibration produced when the string of a musical instrument is plucked, and similar sounds.
The term came to be applied to a nasal vocal resonation, and was historically used to describe "a disagreeable resonance".
[1] Later, however, the term came to be more broadly associated with regional dialects, to the extent that in some locations, "a twang is a desirable commodity".
