Although the concerto consists of three movements in a standard fast–slow–fast structure and each movement follows a traditional form, the concerto was innovative and included many novel features for its time. Distinctive aspects include the almost immediate entrance of the violin at the beginning of the work (rather than following an orchestral preview of the first movement's major themes, as was typical in Classical-era concertos) and the through-composed form of the concerto as a whole, in which the three movements are melodically and harmonically connected and played (each movement immediately following the previous one without any pauses).(citation needed)
