Referring to the Class of Instruments
Classification is used in formal contexts such as encyclopedias and reference books:
The violin refers to any and all violins of the class of stringed instruments called "violin" . For example, an encyclopedia of stringed instruments uses "the" to distinguish the "the violin family" from all other categories: the viola, the cello, the double bass.
"The violin emerged in its definitive form between 1520 and 1550 in Northern Italy."
