As a result of the popularity of the piece, "on the G string" remained in the name of various arrangements whether or not a string instrument playing on its G string was involved. Most of these versions have in common that the original melody of the first violins is played in the low register of a solo instrument, accompanied by a reduction of the
String (structure) playability. The invention of wound strings, such as nylon covered in wound metal, was a crucial step in string instrument technology, because a metal-wound string can produce a lower pitch than a catgut string of similar thickness. This enabled stringed instruments to be made with less thick bass strings. On string instruments that the player plucks or bows directly (e.g., double bass), this enabled instrument makers to use thinner strings for the lowest-pitched strings, which made the lower-pitch strings easier to play. On stringed instruments in which the player presses a keyboard, causing a mechanism to strike the strings, such
