No, Mozart was a classical composer.

Mozart wrote five violin concerti all in very quick succession, in the year 1775 when Mozart was 19. The keys they are in are as follows:

1. B-flat major

2. D major

3. G major

4. D major

5. A major

There is also the supreme sinfonia concertante for violin and viola from the year 1779, which is in E-flat major. It's only sort of a violin concerto, but you must listen to it this moment if you haven't heard it before.
