The term "second violinist" refers to a musician who plays the violin in an orchestra or chamber ensemble, but is not the lead or principal violinist. Other terms that can be used to describe this position include "assistant violinist," "co-concertmaster," or "associate violinist." In some orchestras, the second violinists may be grouped into sections such as "second violins" or "violin II," and may also be referred to as "section violinists." Regardless of the title used, the role of the second violinist is essential in creating the lush harmonies and intricate textures that can be heard in orchestral and ensemble music.
