The strings are the biggest section, although there are only five kinds of instruments: violin, viola, cello, double bass, and harp. This is because they are playing most of the time and usually form the basis of the music. If they are not playing the tune they will probably be accompanying. The first and second violins play different notes: the firsts usually have the tune. The strings sit at the front of the stage in a fan-shape in front of the conductor. The first violins are on the conductor's left, then come the second violins, then the violas and then the cellos. The double basses are behind the cellos. Some conductors prefer to have the second violins on their right and the cellos between the first violins and violas (see image of the Dohnanyi Orchestra).
