The term "second violins" refers to a section of the string instrument family in an orchestra, specifically the group of violinists who play the second part in a musical composition. This section typically complements the first violins, which play the melody, by providing harmony and counterpoint. In orchestral settings, second violins often have a crucial role in enriching the overall sound. They may play different notes or rhythms than the first violins, contributing to the texture of the music. Both sections work together to create a balanced and harmonious performance, enhancing the work of composers like Ludwig van Beethoven and Wolfgang Amadeus Mozart.
