The term "first violins" refers to the section of a string orchestra or ensemble that plays the highest-pitched violin parts. These musicians typically perform the melody and are often responsible for leading the string section. In orchestras, the first violins sit to the left of the conductor and are crucial for setting the tone and style of the music. First violins usually play from a score that includes both individual parts and the full orchestral arrangement. They often work closely with the concertmaster, who is the lead violinist and helps coordinate the section. This role requires strong technical skills and a deep understanding of musical interpretation.
