The term "First Violins" refers to the section of a symphony orchestra or string ensemble that plays the highest-pitched violin parts. These musicians are typically responsible for carrying the melody and often play more complex and prominent musical lines. The First Violins are crucial in creating the overall sound and texture of the orchestra. In an orchestra, the First Violins are usually led by the concertmaster, who is the principal violinist. The concertmaster plays a key role in tuning the orchestra and often performs solo passages. The First Violins work closely with the Second Violins and other sections to achieve a cohesive performance.
