What instruments are traditionally placed in the front of orchestra?

The instruments traditionally placed in the front of an orchestra are the strings, which include the violins, violas, cellos, and double basses. These instruments are positioned at the front because they play the highest-pitched notes and carry the melody of the orchestral sound. The violins are typically seated in four sections: first violins, second violins, violas, and cellos. The double basses are usually placed behind the cellos.
