It is perhaps the best-known of a number of pieces that have the apparently contradictory title Concerto for Orchestra. This is in contrast to the conventional concerto form, which features a solo instrument with orchestral accompaniment. Bartók said that he called the piece a concerto rather than a symphony because of the way each section of instruments is treated in a soloistic and virtuosic way (wiki).
